Verb Forms: Be/Have/Do and Regular/Irregular Verbs

Explanation and Examples

Verb forms are the different ways verbs change to show tense, voice, mood, or other grammatical features. In English, there are regular and irregular verbs.

  • Regular verbs: These verbs follow a consistent pattern when changing forms, usually by adding -ed for past simple and past participle forms.
  • Irregular verbs: These verbs have unique forms for past simple and past participle that do not follow the regular pattern.

The verbs "be," "have," and "do" are essential because they are used as auxiliary verbs and have irregular forms in the past tense.

Regular and Irregular Verb Forms

Regular verbs follow a pattern when forming their past simple and past participle forms, usually by adding -ed.

Example:

workworkedworked

Irregular verbs have unique forms for past simple and past participle that do not follow the regular pattern.

Examples:

Simple Present

The simple present or present simple is a form that combines present tense with "simple" (neither perfect nor progressive) aspect.

In the indicative mood it consists of the base form of the verb, or the -s form when the subject is third-person singular (the verb be uses the forms am, is, are). However, with non-auxiliary verbs it also has a periphrastic form consisting of do (or third-person singular does) with the bare infinitive of the main verb — this form is used in questions (and other clauses requiring inversion and negations, and sometimes for emphasis.

The principal uses of the simple present are given below.

To refer to an action or event that takes place habitually. Such uses are often accompanied by frequency adverbs and adverbial phrases such as always, often, from time to time and never.
Examples:

  • I always take a shower.
  • He writes for a living.

This contrasts with the present progressive, which is used for actions taking place at the present moment.

With stative verbs in senses that do not use progressive aspect, to refer to a present or general state, whether temporary, permanent or habitual. (In senses that do use progressive aspect, the present simple is used when the state is permanent or habitual.)

  • You are happy.
  • I know what to do.
  • Denmark lies to the north of Germany.

When quoting someone or something, even if the words were spoken in the (usually very recent) past:

  • The label says "External use only".
  • Mary says she's ready.

To refer to a single completed action, as in recounting the events of a story in the present tense (see historical present), and in such contexts as newspaper headlines, where it replaces the present perfect:

  • In Hamlet, Ophelia drowns in a stream.
  • 40-year-old wins gold medal.

Sometimes to refer to an arranged future event, usually with a reference to time:

  • We leave for Berlin tomorrow at 1 pm.

In providing a commentary on events as they occur, or in describing some theoretical sequence of events:

  • I chop the chives and add them to the mixture.
  • According to the manager's new idea, I welcome the guests and you give the presentation.

In many dependent clauses referring to the future, particularly condition clauses, clauses expressing place and time, and many relative clauses (see below):

  • If he finds your sweets, he will eat them.
  • We will report as soon as we receive any information.

In certain situations in a temporal adverbial clause, rather than the present progressive:

  • We can see the light improving as we speak.

In colloquial English it is common to use can see, can hear for the present tense of see, hear, etc., and have got for the present tense of have (denoting possession.

See have got and can see below.

For the present subjunctive, see subjunctive.

For uses of modal verbs (which may be regarded as instances of the simple present) see modal verbs.

Present progressive

The present progressive or present continuous form combines present tense with progressive aspect. It thus refers to an action or event conceived of as having limited duration, taking place at the present time. It consists of a form of the simple present of be together with the present participle of the main verb and the ending -ing.

  • We are cooking dinner now.

This often contrasts with the simple present, which expresses repeated or habitual action (We cook dinner every day). However, sometimes the present continuous is used with always, generally to express annoyance about a habitual action:

  • You are always making a mess in the study.

Certain stative verbs do not use the progressive aspect, so the present simple is used instead in those cases. The present progressive can be used to refer to a planned future event:

  • We are tidying the attic tomorrow.

It also appears with future reference in many condition and time clauses and other dependent clauses:

  • If he*'s sleeping* when you arrive, wake him up.
  • I will finish the job while the children are playing.

It can also refer to something taking place not necessarily at the time of speaking, but at the time currently under consideration, in the case of a story or narrative being told in the present tense (as mentioned above under present simple):

  • The king and queen are conversing when Hamlet enters. For the possibility of a present subjunctive progressive, see English subjunctive.

Present Perfect

The present perfect (traditionally called simply the perfect) combines present tense with perfect aspect, denoting the present state of an action's being completed, that is, that the action took place before the present time. (It is thus often close in meaning to the simple past tense, although the two are not usually interchangeable.) It is formed with the present tense of the auxiliary have (namely have or has) and the past participle of the main verb.

The choice of present perfect or past tense depends on the frame of reference (period or point in time) in which the event is conceived as occurring. If the frame of reference extends to the present time, the present perfect is used. For example:

  • I have written a letter this morning. (if it is still the morning)
  • He has produced ten plays. (if he is still alive and professionally active)
  • They have never traveled abroad. (if they are still alive and considered capable of traveling)

If the frame of reference is a time in the past, or a period that ended in the past, the past tense is used instead. For example:

  • I wrote a letter this morning (it is now afternoon);
  • He produced ten plays (he is now dead or his career is considered over, or a particular past time period is being referred to);
  • They never traveled abroad (similarly).

See Simple past for more examples.

The simple past is generally used when the occurrence has a specific past time frame – either explicitly stated (*I wrote a book in 1995; *the water boiled a minute ago), or implied by the context (for example, in the narration of a sequence of events). It is therefore normally incorrect to write a sentence like I have written a novel yesterday; the present perfect cannot be used with an expression of past time such as yesterday.

With already or yet, traditional usage calls for the present perfect: ''Have you eaten yet? Yes, I've already eaten.* However, current informal American speech tends to use the simple past: *Did you eat yet? Yes, I ate already.''

Use of the present perfect often draws attention to the present consequences of the past action or event, as opposed to its actual occurrence. The sentence she has come probably means she is here now, while the simple past she came does not. The sentence, "Have you been to the fair?" suggests that the fair is still going on, while the sentence, "Did you go to the fair?" could mean that the fair is over. (See also been and gone below.) Some more examples:

  • I have eaten. (implies that I'm no longer hungry)
  • We have made the dinner. (implies that the dinner is now ready to eat)
  • The weather has gotten cloudier. (implies that it is now more cloudy than previously)

It may also refer to an ongoing state or habitual action, particularly in saying for how long, or since when, something is the case. For example:

  • I have lived in Paris for five years.
  • He has held the record since he won his Olympic gold.
  • We have eaten breakfast together every morning since our honeymoon.

This implies that I still live in Paris, that he still holds the record and that we still eat together every morning (although the first sentence may also refer to some unspecified past period of five years).

When the circumstance is temporary, the present perfect progressive is often appropriate in such sentences (see below); however, if the verb is one that does not use the progressive aspect, the basic present perfect is used in that case too:

  • Amy has been on the swing for ten minutes.

The present perfect may refer to a habitual circumstance, or a circumstance being part of a theoretical or story narrative being given in the present tense (provided the circumstance is of an event's having taken place previously):

  • Whenever I get home, John has usually already arrived.
  • According to the plan, the speeches have already been given when the cake is brought out.

The present perfect may also be used with future reference, instead of the future perfect, in those dependent clauses where future occurrence is denoted by present tense. For example:

  • When you have written it, show it to me.

Present Perfect Progressive

The present perfect progressive (or present perfect continuous) construction combines some of this perfect progressive aspect with present tense.

It is formed with the present tense of have (have or has), the past participle of be (been), and the present participle of the main verb and the ending "-ing"

This construction is used for ongoing action in the past that continues right up to the present or has recently finished:

  • I have been writing this paper all morning.
  • Why are his eyes red? He has been crying.

It is frequently used when stating for how long, or since when, something is the case:

  • She has been working here since 1997.
  • How long have you been sitting there?
  • They have been arguing about it for two weeks.

In these sentences the actions are still continuing, but it is the past portion of them that is being considered, and so the perfect aspect is used. (A sentence without perfect aspect, such as I am sitting here for three hours, implies an intention to perform the action for that length of time.)

With stative verbs that are not used in the progressive, and for situations that are considered permanent, the present perfect (nonprogressive) is used instead.

Simple

"Simple" forms of verbs are those appearing in constructions not marked for either progressive or perfect aspect (I go, I don't go, I went, I will go, etc., but not I'm going or I have gone).

Simple constructions normally denote a single action (perfective aspect), as in Brutus killed Caesar, a repeated action (habitual aspect), as in I go to school, or a relatively permanent state, as in We live in Dallas. They may also denote a temporary state (imperfective aspect), in the case of stative verbs that do not use progressive forms.

Perfect

The perfect aspect is used to denote the circumstance of an action's being complete at a certain time. It is expressed using a form of the auxiliary verb have (appropriately conjugated for tense etc.) together with the past participle of the main verb: She has eaten it; We had left; When will you have finished?

Perfect forms can also be used to refer to states or habitual actions, even if not complete, if the focus is on the time period before the point of reference (We had lived there for five years). If such a circumstance is temporary, the perfect is often combined with progressive aspect.

The implications of the present perfect (that something occurred prior to the present moment) are similar to those of the simple past, although the two forms are generally not used interchangeably – the simple past is used when the time frame of reference is in the past, while the present perfect is used when it extends to the present.

For all uses of specific perfect constructions, see the sections on the present perfect, past perfect, future perfect and conditional perfect.

By using nonfinite forms of the auxiliary have, perfect aspect can also be marked on infinitives (as in should have left and expect to have finished working), and on participles and gerunds (as in having seen the doctor).

Note that while all of the constructions referred to here are commonly referred to as perfect (based on their grammatical form), some of them, particularly nonpresent and nonfinite instances, might not be considered truly expressive of the perfect aspect. This applies particularly when the perfect infinitive is used together with modal verbs: for example, he could not have been a genius might be considered (based on its meaning) to be a past tense of he cannot/could not be a genius; such forms are considered true perfect forms by some linguists but not others.

Perfect Progressive

The perfect and progressive (continuous) aspects can be combined, usually in referring to the completed portion of a continuing action or temporary state: I have been working for eight hours. Here a form of the verb have (denoting the perfect) is used together with been (the past participle of be, denoting the progressive) and the present participle of the main verb.

In the case of the stative verbs, which do not use progressive aspect, the plain perfect form is normally used in place of the perfect progressive: I've been here for half an hour (not I've been being here...).

Active and Passive Voice

The active voice (where the verb's subject is understood to denote the doer, or agent), of the denoted action) is the unmarked voice in English.

To form the passive voice (where the subject denotes the undergoer, or patient), of the action), a periphrastic construction is used.

In the canonical form of the passive, a form of the auxiliary verb be (or sometimes get) is used, together with the past participle of the lexical verb. Passive voice can be expressed in combination together with tenses, aspects and moods, by means of appropriate marking of the auxiliary (which for this purpose is not a stative verb, i.e. it has progressive forms available).

For example:

  • This room is tidied regularly. (simple present passive)
  • It had already been accepted. (past perfect passive)
  • Dinner is being cooked right now. (present progressive passive)

The passive forms of certain of the combinations involving the progressive aspect are quite rare; these include the present perfect progressive (it has been being written), past perfect progressive (it had been being written), future progressive (it will be being written), future perfect progressive (it will have been being written), conditional progressive (it would be being written) and conditional perfect progressive (it would have been being written). Because of the awkwardness of these constructions, they may be paraphrased, for example using the expression in the process of (it has been in the process of being written, it will be in the process of being written, and similar).

The uses of these various passive forms are analogous to those of the corresponding tense–aspect–mood combinations in the active voice.

Participle

Participles are verb forms that do double duty — they help build tenses and voices, but they also work as adjectives and adverbs. Understanding both types of participles is essential for forming correct verb tenses, using the passive voice, and writing more sophisticated sentences.

The Two Participles

English has two participles:

  1. Present participle — formed by adding -ing to the base verb: doing, running, sleeping. It's identical in form to the gerund, but serves a different function (more on that below).
  2. Past participle — for regular verbs, it's the -ed form (walked, boiled). For irregular verbs, it varies widely: done, written, sung, gone.

How the Present Participle Is Used

  • Progressive tenses: She is reading a book.
  • As an adjective: The woman sitting by the window is my boss.
  • As an adverb: Looking up from his phone, he noticed the bus had arrived.
  • In absolute constructions (with its own subject): The weather being terrible, we cancelled the trip.

Present participles used as adjectives carry an active meaning — an exciting movie is one that excites you.

How the Past Participle Is Used

  • Perfect tenses: They have finished the project.
  • Passive voice: The email was sent this morning.
  • As an adjective: The broken window needs replacing.
  • Adverbially: Exhausted from the hike, we fell asleep immediately.

Past participles used as adjectives usually carry a passive meaning — the attached file is one that has been attached. However, past participles of intransitive verbs can have active meaning: fallen leaves (leaves that have fallen).

Participle vs. Gerund

Both the present participle and the gerund end in -ing, but they do different jobs. The participle acts as an adjective or adverb; the gerund acts as a noun.

  • Swimming in the lake, she felt completely free. (participle — describes she)
  • Swimming is her favourite hobby. (gerund — subject of the sentence)

The famous example Flying planes can be dangerous is ambiguous: flying could be a gerund ("the activity of flying planes") or a participle ("planes that fly").

Self-check: If you can replace the -ing word with a noun like "it" or "the activity," it's a gerund. If it describes a noun or tells you more about an action, it's a participle.

Watch Out: Past Tense vs. Past Participle

For regular verbs, the past tense and past participle look the same (walked, played). For many irregular verbs, they differ:

  • ✅ I went home early. (past tense)
  • ✅ I have gone home early. (past participle)
  • ❌ I should have went home early.

If you're unsure, check whether the verb follows a helping word like have, has, or had — if it does, you need the past participle form.

Irregular Verbs

The English language has a large number of irregular verbs, approaching 200 in normal use—and significantly more if prefixed forms are counted. In most cases, the irregularity concerns the past tense (also called preterite or the past participle.

The other inflected parts of the verb—the third person singular present indicative in -[e]s, and the present participle and gerund form in -ing—are formed regularly in most cases. There are a few exceptions: the verb be has irregular forms throughout the present tense; the verbs have, do, go and say have irregular -[e]s forms; and certain defective verbs (such as the modal auxiliaries) lack most inflection.

The irregular verbs include many of the most common verbs: the dozen most frequently used English verbs are all irregular. New verbs (including loans from other languages, and nouns employed as verbs) usually follow the regular inflection, unless they are compound formations from an existing irregular verb (such as housesit, from sit).

Irregular verbs in Modern English typically derive from verbs that followed more regular patterns at a previous stage in the history of the language. In particular, many such verbs derive from Germanic strong verbs, which make many of their inflected forms through vowel gradation, as can be observed in Modern English patterns such as sing–sang–sung. The regular verbs, on the other hand, with their preterites and past participles ending in -ed, follow the weak conjugation, which originally involved adding a dental consonant (-t or -d). Nonetheless, there are also many irregular verbs that follow or partially follow the weak conjugation.

For information on the conjugation of regular verbs in English, as well as other points concerning verb usage, see verbs.

Strong Verbs

A large number of the irregular verbs derive from Germanic strong verbs, which display the vowel shift called ablaut, and do not add an ending such as -ed or -t for the past forms. These sometimes retain past participles with the ending -[e]n, as in give–gave–given and ride–rode–ridden, but in other cases this ending has been dropped, as in come–came–come and sing–sang–sung. This verb group was inherited from the parent Proto-Germanic language, and before that from the Proto-Indo-European language. It was originally a system of regular verbs, and in modern German the system remains more or less regular; however in Modern English relatively few verbs continue to follow such a pattern, and they are classed as irregular.

Verbs that retain a strong-type inflection in modern English and add -[e]n in the past participle include bear, beat, beget, bite, blow, break, choose, cleave, draw, drive, eat, fall, fly, forbid, forget, forsake, freeze, give, grow, know, lie, ride, rise, see, shake, shear, slay, smite, speak, steal, stride, strive, swear, take, tear, throw, tread, wake, weave, and write.

Those that do not add -[e]n in the usual past participle include become, begin, bind, burst, cling, come, drink, fight, find, fling, get (but with past participle gotten in American English), grind, hang, hold, let, ring, run, seek, shed, shine, shit, shoot, shrink, sing, sink, sit, slide, sling, slink, slit, spin, spring, stand, sting, stink, strike, swim, swing, win, wind and wring.

The verbs sow and swell are now usually regular in the past tense, but retain the strong-type past participles sown and swollen. Other verbs retain participles in -n for certain adjectival uses, such as drunken and sunken. The verb crow is now regular in the past participle, but the strong past tense crew is sometimes used.

Some originally weak verbs have taken on strong-type forms by analogy with strong verbs. These include dig, dive (when dove is used as the past tense), hide, mow, prove (when proven is used as the past participle), saw (past participle sawn), sew (past participle sewn), show (past participle shown), spit, stick, strew, string, and wear (analogy with bear).

Weak Verbs

Some other irregular verbs derive from Germanic weak verbs, forming past tenses and participles with a -d or -t ending (or from originally strong verbs that have switched to the weak pattern). The weak conjugation is also the origin of the regular verbs in -ed; however various historical sound changes (and sometimes spelling changes) have led to certain types of irregularity in some verbs. The main processes are as follows (some verbs have been subject to more than one of these).

  • Some weak verbs with long vowels in their present tense stems (such as keep) took a short vowel in the past tense and past participle (kept).
  • In some weak verbs ending in a final -t or -d, this final consonant coalesced (contracted) with the weak past ending to leave a single -t or -d in the past forms.
  • Some verbs ending in l or n had their past ending irregularly devoiced to -t, and in a few verbs ending with a v or z sound (leave, lose), both that sound and the past ending were devoiced. (The regular ending -ed is also devoiced after voiceless consonants in regular verbs, as described under, but this is not now shown in the spelling – for example, the -ed in blessed and whipped is pronounced as a t, and these words were formerly written blest and whipt. The spelling -t following a voiceless consonant is retained for verbs that display an irregularity, as in kept and cost.)
  • Some weak verbs continue the vowel shift called Rückumlaut ("reverse umlaut"); those with -gh- in the spelling were also affected by the Germanic spirant law.
  • A few weak verbs have undergone additional contractions or vowel shortenings in their past or present tense forms.
  • A few verbs are regular in their spoken forms, but have irregular spelling.

The irregular weak verbs (being in normal use) can consequently be grouped as follows:

For weak verbs that have adopted strong-type past tense or past participle forms, see the section above on strong verbs.

More information on the development of some of the listed verbs can be found at List of irregular verbs.

  • Verbs with vowel shortening: creep, flee, hear, keep, leap, shoe (when shod is used), sleep, sweep and weep. (Of these, creep, flee, leap, sleep and weep derive from verbs that were originally strong.)
  • Verbs with vowel shortening and devoicing of the ending: deal, dream, feel, kneel, lean, leave, lose (originally strong) and mean. Some of the verbs in this and in the preceding group have alternative regular forms, such as dreamed and leaped.
  • Verbs with coalescence of consonants: bet, bid, cast, cost, cut, fit, hit, hurt, knit, put, quit, rid, set, shed, shut, split, spread, thrust, wed and wet. Some of these verbs have alternative regular forms, such as wedded and wetted. (The verb hoist behaves similarly to verbs in this group, but this was originally itself a past form of the now obsolete verb hoise; similarly clad was originally – and sometimes still is – a past form of clothe.)
  • Verbs with coalescence of consonants and devoicing of the ending: bend, build, lend, rend, send, spend.
  • Verbs with coalescence of consonants and vowel shortening: bleed, breed, feed, lead, light, meet, read (past tense and past participle also spelt read, but pronounced with a short vowel), and speed.
  • Verbs with devoicing of the ending and no other irregularity: burn, dwell, learn, smell, spell, spill and spoil. Most of these have regular -ed forms as alternatives.
  • Verbs continuing the Rückumlaut pattern: bring–brought, buy–bought, seek–sought, sell–sold, teach–taught, tell–told, and think–thought. The borrowed verb catch (caught) has also fallen into this pattern as a result of analogy.
  • Verbs with additional contractions and shortenings: have–has–had, make–made, say–says–said (where says and said are pronounced with a short vowel ). (The verb do has a similar vowel shortening in does and done)
  • Verbs irregular only in spelling: lay–laid, pay–paid (although in the meaning "let out", of a rope etc., pay may have the regular spelling payed).

Anomalous Cases

The following verbs do not fit exactly into any of the above categories:

  • The modal verbs, which are defective verbs – they have only a present indicative form and (in some cases) a preterite, lacking nonfinite forms (infinitives, participles, gerunds), imperatives, and subjunctives (although some uses of the preterites are sometimes identified as subjunctives). Moreover, they do not add -s in the third person singular – this is because they derive either from preterites, or from Germanic preterite-present verbs, which were conjugated using the (strong-type) preterite form with present tense meaning. (Additional "true" preterites with past tense meaning were formed with the addition of dentals in the manner of the weak verbs.) The chief verbs of this class are can–could, may–might, shall–should, will–would, and must and ought (These last two have no preterites. They were originally preterites themselves). There are also dare and need, which follow the same pattern (no -s) in some contexts: "Dare he jump? She needn't worry" (dare derives from a preterite-present verb, but need is from an Old English regular verb).
  • Two verbs (be and go) that contain suppletive forms, i.e. one or more of their parts came from an entirely different root. With go this applies to the past tense went, which is originally from the verb wend. With be it applies to a number of different forms. Derived from be is the defective verb beware, which does not inflect in normal use and which appears only in those forms in which the plain form of be would be used, namely the infinitive, the imperative, and the subjunctive.
  • The verb do, which has the reduplicated form did for its past tense (an irregularity that can be traced back to Proto-Germanic). Its past participle done can be compared to typical strong participles in -[e]n; however both this and the third person present tense does feature a short vowel in modern pronunciation.

Verbs With Irregular Present Tenses

Apart from the modal verbs, which are irregular in that they do not take an -s in the third person, the only verbs with irregular present tense forms are be, do, have and say (and prefixed forms of these, such as undo and gainsay, which conjugate in the same way as the basic forms).

The verb be has multiple irregular forms. In the present indicative it has am in the first person singular, is in the third person singular, and are in the plural and second person singular. (Its present subjunctive is be, as in "I suggest that you be extremely careful", though that is not irregular, as all verbs use the infinitive/imperative form for the present subjunctive.) It also has two past tense forms: was for the first and third persons singular, and were for the plural and second person singular (although there are certain subjunctive uses in which were can substitute for was). The past participle is been, and the present participle and gerund forms are regular: being.

As mentioned above, apart from its other irregularities, the verb do has the third person present indicative does pronounced with a short vowel.

The verb have has a contracted third person present indicative form: has. This is formed similarly to the verb's past tense had.

The verb say displays vowel shortening in the third person present indicative (although the spelling is regular): says . The same shortening occurs in the past form said . (Compare the diphthong in the plain form say .)

Coincident Forms

In regular English verbs, the past tense and past participle have the same form. This is also true of most irregular verbs that follow a variation of the weak conjugation, as can be seen in the list below. Differences between the past tense and past participle (as in sing–sang–sung, rise–rose–risen) generally appear in the case of verbs that continue the strong conjugation, or in a few cases weak verbs that have acquired strong-type forms by analogy—as with show (regular past tense showed, strong-type past participle shown). However, even some strong verbs have identical past tense and participle, as in cling–clung–clung.

In some verbs, the past tense, past participle, or both are identical in form to the basic (infinitive) form of the verb. This is the case with certain strong verbs, where historical sound changes have led to a leveling of the vowel modifications: for example, let has both past tense and past participle identical to the infinitive, while come has the past participle identical (but a different past tense, came). The same is true of the verbs listed above under as having undergone coalescence of final consonants (and without other irregularities such as vowel shortening or devoicing of the ending): bet, bid, etc. (these verbs have infinitive, past tense and past participle all identical, although some of them also have alternative regular forms in -ed). The verb read has the same spelling in all three forms, but not the same pronunciation, as it exhibits vowel shortening.

In a few cases the past tense of an irregular verb has the same form as the infinitive of a different verb. For example, bore and found may be past tenses of bear and find, but may also represent independent (regular) verbs of different meaning. Another example is lay, which may be the past tense of lie, but is also an independent verb (regular in pronunciation, but with irregular spelling: lay–laid–laid). In fact lay derives from a causative of the verb from which lie derives. The two verbs are sometimes confused, with lay used in the intransitive senses prescriptively reserved for lie.

Prefixed Verbs

Nearly all of the basic irregular verbs are single-syllable words. (Their irregular inflected forms are normally single-syllable also, except for the past participles in -en like chosen and risen.) However many additional irregular verbs are formed by adding prefixes to the basic ones: understand from stand, become from come, mistake from take, and so on. (These prefixed forms are generally omitted from the list below, but a large number appear in the table at List of English irregular verbs.) As a general rule, prefixed verbs are conjugated identically to the corresponding basic verbs; for example, we have understand–understood–understood and become–became–become, following the patterns of stand–stood–stood and come–came–come. However, there are occasional differences: in British English, for instance, the past participle of get is got, while that of forget is forgotten.

Only a few irregular verbs of more than one syllable cannot be analyzed as prefixed compounds of monosyllables. The only ones in normal use are begin–began–begun and forsake–forsook–forsaken (these both derive from prefixed verbs whose unprefixed forms have not survived into Modern English). There is also beseech–besought–besought (this is from Old English besēcan "to seek or inquire about", making it equivalent to be- + seek, but it has moved away from seek in both form and meaning); however the form besought is now archaic, the verb normally being conjugated regularly (beseeched).

English Grammar Basics

"English Grammar Basics" tag marks quiz and explainers that intend to provide a solid foundation in English language grammar. This includes all the major concepts and topics in English grammar, including nouns, verbs, adjectives, adverbs, prepositions, conjunctions, tenses, voice, mood, and sentence structure. The explanations we provide in quiz intro sections are clear and concise, making it easy for learners of all levels to understand. These quizzes are designed to be fun and engaging, helping you to retain the information more effectively. Whether you're a beginner or looking to refresh your knowledge, look for content marked with the "English Grammar Basics" tag for everything you need to master English language grammar.

A1 | Elementary | Beginners

CEFR A1 is the first level of the Common European Framework of Reference for Languages (CEFR), a widely used standard for measuring language ability. If you're just starting to learn English — or rebuilding from scratch — this is where you begin.

What can an A1 learner do?

At A1, you can handle the most basic, everyday communication. Specifically, you're expected to:

  • Understand and use familiar everyday expressions — greetings, simple questions, common signs and instructions.
  • Introduce yourself and others — say where you live, talk about people you know, describe things you have.
  • Ask and answer simple personal questions — "What's your name?", "Where are you from?", "Do you have a car?"
  • Have short conversations — as long as the other person speaks slowly and clearly and is willing to help.

What grammar does A1 cover?

A1 focuses on the building blocks of English grammar. You'll work with:

  • Basic verb forms — the present tense of be, have, and do, plus simple regular and irregular verbs
  • Simple sentence structure — subject + verb + object word order
  • Common determiners and pronounsa, the, this, my, he, she, it
  • Basic prepositionsin, on, at, to, from
  • Simple questionsyes/no questions and wh- questions (what, where, who)
  • Everyday vocabulary and collocations — phrases that naturally go together, like make breakfast or do homework

How do you know if you're A1?

If you can read a short text like a menu or a bus sign, fill out a simple form with your personal details, and ask someone basic questions in English — you're operating at A1. If most of that still feels challenging, you're in exactly the right place.

Self-check: Try introducing yourself in five sentences — your name, where you're from, what you do, something you like, and one question for the other person. If you can do that (even with mistakes), you're solidly at A1.

What's next?

Once you're comfortable with A1 basics, you'll move toward A2, where sentences get longer, tenses expand, and you start handling more real-world situations.

A2 | Elementary | Pre-intermediate

CEFR A2 is the second level in the Common European Framework of Reference for Languages, often called elementary or pre-intermediate. If you're at this stage, you've moved beyond the basics of A1 and can handle simple, real-life communication — but you're still building the foundations you'll need for B1 and beyond.

What can an A2 learner do?

At A2, you can:

  • Understand everyday expressions related to familiar topics — personal details, family, shopping, work, and your local area.
  • Communicate in routine situations that involve a simple, direct exchange of information (e.g. ordering food, asking for directions, making small talk).
  • Describe your background and immediate environment in simple terms — where you live, what you do, what you need.
  • Read and understand short, simple texts like signs, menus, timetables, and brief personal messages.

Key grammar at A2

At this level, you're expected to be comfortable with several core grammar areas:

  • Past simple and past continuous — talking about completed actions and actions in progress in the past.
  • Present perfect — connecting past events to the present (I've visited London twice).
  • Basic modal verbs — expressing ability, permission, necessity, and possibility (can, must, should, have to).
  • Common question forms — both simple and slightly more complex (How long have you lived here?).
  • Articles and determiners — using a/an/the correctly, along with words like some, any, few, little.
  • Basic conditionals — first conditional and simple uses of if and wish.

You're also expanding your vocabulary through collocations (natural word pairings like make a decision or take a break) and learning to use gerunds and infinitives with common verbs.

How A2 differs from A1 and B1

Compared to A1, A2 learners can do more than just produce isolated phrases — you can link simple sentences and participate in short conversations. Compared to B1, you're still relying on familiar contexts and predictable language; handling unexpected topics or expressing opinions in detail comes at the next level.

Self-check: If you can describe your daily routine, talk about past experiences, and handle a basic conversation at a shop or restaurant — but struggle when the topic gets abstract or unfamiliar — you're likely at A2.

B1 | Intermediate

B1 is the intermediate level of the Common European Framework of Reference for Languages (CEFR). It marks the point where you move beyond survival English and start expressing yourself with real independence — describing experiences, explaining opinions, and handling everyday situations without a script.

What a B1 user can do

At this level, you're expected to:

  • Understand the main points of clear, standard speech and writing on familiar topics — work, school, travel, hobbies.
  • Handle most travel situations in English-speaking environments.
  • Produce simple connected text on topics you know or care about.
  • Describe experiences, events, hopes, and plans, and give brief reasons and explanations for your opinions.
  • Communicate in routine tasks that require a straightforward exchange of information.

What B1 grammar looks like

B1 is where grammar starts to get more layered. You're not just forming basic sentences anymore — you're combining ideas, using different tenses with more precision, and starting to handle structures like the passive voice, modal verbs for necessity and possibility, and gerunds vs. infinitives. You're also expected to build complex sentences with linking words and dependent clauses.

Typical B1 grammar areas include:

  • Future tenses — distinguishing will, going to, and the present continuous for future plans
  • Passive voiceThe report was written yesterday.
  • Modal verbsYou should apply early. / She might be late.
  • Used toI used to live in Berlin.
  • Verb patterns — knowing whether a verb takes a gerund, an infinitive, or both (I enjoy reading vs. I decided to leave)

What B1 doesn't mean

B1 speakers still hesitate, make grammatical errors, and sometimes struggle with less familiar topics. That's normal. The key difference from A2 is that you can keep a conversation going and get your point across even when things aren't perfect. The step up to B2 involves handling more abstract topics, understanding nuance, and producing more complex, accurate language.

Self-check: Can you tell a friend about a recent trip — what happened, what you liked, and what you'd do differently — without switching to your native language? If yes, you're likely operating at B1 or above.
