The verb "to be" is used in its past progressive form "was" for the singular subject "cat," followed by the present participle "sitting." This indicates an ongoing action in the past. The correct simple past form of "to jump" is "jumped."
Verb
A verb is a word that expresses an action, a state, or an occurrence — and it's the engine of every English sentence. Understanding how verbs work is foundational to everything else in English grammar, from forming questions to building complex sentences.
Verb Forms
Most English verbs have five inflected forms:
- Base form (go, write, climb) — used as an infinitive, imperative, present subjunctive, and present indicative in all persons except third-person singular.
- -s form (goes, writes, climbs) — used for the present tense, third-person singular (she writes).
- Past tense (went, wrote, climbed) — also called the preterite.
- Past participle (gone, written, climbed) — identical to the past tense for regular verbs, but often different for irregular verbs.
- -ing form (going, writing, climbing) — serves as the present participle and gerund.
The verb be is a special case with more forms than any other English verb (am, is, are, was, were, been, being). Modal verbs like can, must, and should have fewer forms than typical verbs.
Main Verbs and Auxiliaries
Verbs in English often appear in combinations: one or more auxiliary verbs paired with a main verb.
- The dog was barking very loudly.
- My hat has been cleaned.
- Jane does not really like us.
The first verb in the combination is the finite verb (it carries tense and agrees with the subject). The rest are nonfinite (infinitives or participles). Notice that these verbs don't always sit next to each other — as in does not really like.
Tense, Aspect, and Mood
English expresses tense (time reference), aspect (how an action unfolds over time), and mood (the speaker's attitude toward the action) mostly through verb combinations rather than word endings. That's why you'll encounter labels like "present progressive" or "conditional perfect" — these are specific tense–aspect–mood combinations built with auxiliaries.
Self-check: If you can change the time of a sentence by swapping one word (She runs → She ran), that word is the verb.

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.
Progressive
The progressive or continuous aspect is used to denote a temporary action or state that began at a previous time and continues into the present time (or other time of reference). It is expressed using a form of the auxiliary verb to be (conjugated appropriately for tense etc.) together with the present participle (-ing form) of the main verb: I am reading; Were you shouting?; He will be sitting over there.
Certain stative verbs make limited use of progressive aspect. Their nonprogressive forms (simple or nonprogressive perfect constructions) are used in many situations even when expressing a temporary state.
The main types are described below.
- The copular verb to be does not normally use progressive forms (I am happy, not I am being happy). However its progressive aspect is used in appropriate situations when the verb expresses the passive voice (We are being followed), and when it has the meaning of "behave" or "act as" (You are being very naughty; He's being a pest).
- The verb to have does not use progressive forms when it expresses possession), broadly understood (I have a brother, not I'm having a brother), but it does use them in its active meanings (I'm having a party; She's having a baby; He was having a problem starting his car). Other verbs expressing a state of possession or similar, such as possess, own, belong and owe, also do not normally use progressive forms.
- Verbs of mental state, sense perception and similar (know, believe, want, think, see, hear, need, etc.) are generally used without progressive aspect, although some of them can be used in the progressive to imply an ongoing, often temporary situation (I am feeling lonely), or an activity (I am thinking about a problem).
- Verbs denoting positional state normally do use the progressive if the state is temporary: He is standing in the corner. (Compare permanent state: London stands on the banks of the Thames.)
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...).
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.
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.
