Adjective

An adjective is a word that describes or modifies a noun or pronoun, giving more information about its qualities, state, or identity. Adjectives are one of the core parts of speech in English, and you use them constantly — to describe people, objects, feelings, and ideas.

What adjectives do

Adjectives typically answer questions like What kind?, Which one?, or How many? They can appear in two main positions:

• Before a noun (called attributive position): a tall building, fresh coffee, three students
• After a linking verb (called predicative position): The soup is hot, She seems tired

Some adjectives work in only one position. For example, main is almost always attributive (the main reason), while asleep is almost always predicative (The baby is asleep).

Examples

• ✅ She wore a red dress. (red modifies dress)
• ✅ The exam was difficult. (difficult follows the linking verb was)
• ❌ She wore a redly dress. (Adverbs like redly don't modify nouns.)
• ✅ He gave me useful advice. (useful modifies the uncountable noun advice)

Adjective order

When you stack multiple adjectives before a noun, English follows a conventional order: opinion → size → age → shape → colour → origin → material → purpose. For example, a lovely small old round brown French wooden serving table — though in real life you'd rarely pile up that many.

Self-check: If your sentence sounds awkward with two adjectives before a noun, try swapping their order. The version that "sounds right" usually follows the standard sequence.

Adjectives vs. determiners

Words like the, this, my, and some were historically grouped with adjectives, but modern grammar classifies them as determiners. Unlike true adjectives, determiners don't have comparative forms (bigger works, but *more the doesn't) and occupy a fixed slot before any adjectives.

Comparatives and superlatives

Most adjectives have comparative and superlative forms used to compare things:

• tall → taller → tallest
• expensive → more expensive → most expensive

Simple Past

The simple past, past simple or past indefinite, sometimes called the preterite, is the basic form of the past tense in Modern English. It is used principally to describe events in the past, although it also has some other uses. Regular English verbs form the simple past in -ed; however there are a few hundred irregular verbs with different forms.

The term "simple" is used to distinguish the syntactical construction whose basic form uses the plain past tense alone, from other past tense constructions which use auxiliaries in combination with participles, such as the past perfect and past progressive.

Formation

Regular verbs form the simple past end*-ed*; however there are a few hundred irregular verbs with different forms. For details see.

Most verbs have a single form of the simple past, independent of the person or number of the subject (there is no addition of -s for the third person singular as in the simple present).

However, the copula verb be has two past tense forms: was for the first and third persons singular, and were in other instances.

The form were can also be used in place of was in conditional clauses and the like; for information on this, see subjunctive.

This is the only case in modern English where a distinction in form is made between the indicative and subjunctive moods in the past tense.

Questions, other clauses requiring inversion, negations with not, and emphatic forms of the simple past use the auxiliary did.

A full list of forms is given below, using the (regular) verb help as an example:

• Basic simple past:
  • I/you/he/she/it/we/they helped
• Expanded (emphatic) simple past:
  • I/you/he/she/it/we/they did help
• Question form:
  • Did I/you/he/she/it/we/they help?
• Negative:
  • I/you/he/she/it/we/they did not (didn't) help
• Negative question:
  • Did I/you/he/she/it/we/they not help? / Didn't I/you/he/she/it/we/they help?

Usage

The simple past is used for a single event (or sequence of such events) in the past, and also for past habitual action:

• He took the money and ran.
• I visited them every day for a year.

It can also refer to a past state:

• I knew how to fight even as a child.

For action that was ongoing at the time referred to, the past progressive is generally used instead (e.g. I was cooking). The same can apply to states, if temporary (e.g. the ball was lying on the sidewalk), but some stative verbs do not generally use the progressive aspect at all, and in these cases the simple past is used even for a temporary state:

• The dog was in its kennel.

However, with verbs of sensing, it is common in such circumstances to use could see in place of saw, could hear in place of heard, etc.

• I felt cold.

If one action interrupts another, then it is usual for the interrupted (ongoing) action to be expressed with the past progressive, and the action that interrupted it to be in the simple past:

• Your mother called while you were cooking.

The simple past is often close in meaning to the present perfect.

The simple past is used when the event happened at a particular time in the past, or during a period which ended in the past (i.e. a period that does not last up until the present time).

This time frame may be explicitly stated, or implicit in the context (for example the past tense is often used when describing a sequence of past events).

• I was born in 1980.
• We turned the oven off two minutes ago.
• I came home at 6 o'clock.
• When did they get married?
• We wrote two letters this morning.
• She placed the letter on the table, sighed, and left the house.Contrast these examples with those given at.

Note also that for past actions that occurred before the relevant past time frame, the past perfect is used.

Various compound constructions exist for denoting past habitual action.

The sentence When I was young, I played football every Saturday might alternatively be phrased using used to (... I used to play ...) or using would (... I would play...).

The simple past also has some uses in which it does not refer to a past time.

• If he walked faster, he would get home earlier.
• I wish I knew what his name was.

These are generally in condition clauses and some other dependent clauses referring to hypothetical circumstances, as well as certain expressions of wish:

• He said he wanted to go on the slide.

Past Progressive

The past progressive or past continuous construction combines progressive aspect with past tense, and is formed using the past tense of be (was or were) with the present participle of the main verb.

It indicates an action that was ongoing at the past time being considered:

• At three o'clock yesterday, I was working in the garden. For stative verbs that do not use the progressive aspect, the simple past is used instead (At three o'clock yesterday we were in the garden).

The past progressive is often used to denote an action that was interrupted by an event, or for two actions taking place in parallel:

• While I was washing the dishes, I heard a loud noise.
• While you were washing the dishes, Sue was walking the dog.(Interrupted actions in the past can also sometimes be denoted using the past perfect progressive.)

The past progressive can also be used to refer to past action that occurred over a range of time and is viewed as an ongoing situation:

• I was working in the garden all day yesterday. That could also be expressed using the simple past, as I worked..., which implies that the action is viewed as a unitary event (although the effective meaning is not very different).

Past Perfect

The past perfect, sometimes called the pluperfect, combines past tense with perfect aspect; it is formed by combining had (the past tense of the auxiliary have) with the past participle of the main verb.

It is used when referring to an event that took place prior to the time frame being considered.

This time frame may be stated explicitly, as a stated time or the time of another past action:

• We had finished the job by 2 o'clock.
• He had already left when we arrived.

The time frame may also be understood implicitly from the previous or later context:

• I was eating ... I had invited Jim to the meal but he was unable to attend. (i.e. I invited him before I started eating)
• I had lost my way. (i.e. this happened prior to the time of the past events I am describing or am about to describe)

Compare He had left when we arrived (where his leaving preceded our arrival), with the form with the simple past, He left when we arrived (where his leaving was concurrent with or shortly after our arrival).

Note that unlike the present perfect, the past perfect can readily be used with an adverb specifying a past time frame for the occurrence.

For example, while it is incorrect to say I have done it last Friday (the use of last Friday, specifying the past time, would require the simple past rather than the present perfect), there is no such objection to a sentence like "I had done it the previous Friday".

The past perfect can also be used for states or repeated occurrences pertaining over a period up to a time in the past, particularly in stating "for how long" or since when". However, if the state is temporary and the verb can be used in the progressive aspect, the past perfect progressive would normally be used instead. Some examples with the plain past perfect:

• I had lived in that house for 10 years.
• The children had been in their room since lunchtime.

Past Perfect Progressive

The past perfect progressive or past perfect continuous (also known as the pluperfect progressive or pluperfect continuous) combines perfect progressive aspect with past tense.

It is formed by combining had (the past tense of auxiliary have), been (the past participle of be), and the present participle of the main verb.

Uses of the past perfect progressive are analogous to those of the present perfect progressive, except that the point of reference is in the past.

For example:

• I was tired because I had been running.
• By yesterday morning they had already been working for twelve hours.
• Among the witnesses was John Smith, who had been staying at the hotel since July 10.

This form is sometimes used for actions in the past that were interrupted by some event (compare the use of the past progressive as given above).

For example:

• I had been working on my novel when she entered the room to talk to me.

This implies that I stopped working when she came in (or had already stopped a short time before); the plain past progressive (I was working...) would not necessarily carry this implication.

If the verb in question does not use the progressive aspect, then the plain past perfect is used instead.

The past perfect progressive may also have additional specific uses similar to those of the plain past perfect.

Phrasal Verbs

In English, a phrasal verb is a phrase such as turn down or ran into which combines two or three words from different grammatical categories: a verb and a particle and/or a preposition together form a single semantic unit. This semantic unit cannot be understood based upon the meanings of the individual parts, but must be taken as a whole. In other words, the meaning is non-compositional and thus unpredictable. Phrasal verbs that include a preposition are known as prepositional verbs and phrasal verbs that include a particle are also known as particle verbs. Additional alternative terms for phrasal verb are compound verb, verb-adverb combination, verb-particle construction, two-part word/verb, and three-part word/verb (depending on the number of particles), and multi-word verb.

Examples

There are at least three main types of phrasal verb constructions depending on whether the verb combines with a preposition, a particle, or both. The phrasal verb constructions in the following examples are in bold:

Verb + preposition (prepositional phrasal verbs)

When the element is a preposition, it is the head) of a full prepositional phrase and the phrasal verb is thus a prepositional phrasal verb. These phrasal verbs can also be thought of as transitive and non-separable; the complement follows the phrasal verb.

• Who is looking after the kids? – after is a preposition that introduces the prepositional phrase after the kids.
• They picked on nobody. – on is a preposition that introduces the prepositional phrase on nobody.
• I ran into an old friend. – into is a preposition that introduces the prepositional phrase into an old friend.
• She takes after her mother. – after is a preposition that introduces the prepositional phrase after her mother.
• Sam passes for a linguist. – for is a preposition that introduces the prepositional phrase for a linguist.
• You should stand by your friend. – by is a preposition that introduces the prepositional phrase by your friend.

Verb + particle (particle phrasal verbs)

When the element is a particle, it can not (or no longer) be construed as a preposition, but rather is a particle because it does not take a complement. These verbs can be transitive or intransitive. If they are transitive, they are separable.

• They brought that up twice. – up is a particle, not a preposition.
• You should think it over. – over is a particle, not a preposition.
• Why does he always dress down? – down is a particle, not a preposition.
• You should not give in so quickly. – in is a particle, not a preposition.
• Where do they want to hang out? – out is a particle, not a preposition.
• She handed it in. – in is a particle, not a preposition. *

Verb + particle + preposition (particle-prepositional phrasal verbs)

Finally, many phrasal verbs are combined with both a preposition and a particle.

• Who can put up with that? – up is a particle and with is a preposition.
• She is looking forward to a rest. – forward is a particle and to is a preposition.
• The other tanks were bearing down on my panther. – down is a particle and on is a preposition.
• They were really teeing off on me. – off is a particle and on is a preposition.
• We loaded up on Mountain Dew and Doritos. – up is a particle and on is a preposition
• Susan has been sitting in for me. – in is a particle and for is a preposition.The aspect of these types of verbs that unifies them under the single banner phrasal verb is the fact that their meaning cannot be understood based upon the meaning of their parts taken in isolation: the meaning of pick up is distinct from pick; the meaning of hang out is not obviously related to hang.

Phrase

In everyday speech, a phrase may be any group of words, often carrying a special idiomatic meaning; in this sense it is synonymous with expression. In linguistic analysis, a phrase is a group of words (or possibly a single word) that functions as a constituent in the syntax of a sentence, a single unit within a grammatical hierarchy. A phrase typically appears within a clause, but it is possible also for a phrase to be a clause or to contain a clause within it.

Preposition

Prepositions form a closed word class, although there are also certain phrases that serve as prepositions, such as in front of.

A single preposition may have a variety of meanings, often including temporal, spatial and abstract. Many words that are prepositions can also serve as adverbs. Examples of common English prepositions (including phrasal instances) are of, in, on, over, under, to, from, with, in front of, behind, opposite, by, before, after, during, through, in spite of or despite, between, among, etc.

A preposition is usually used with a noun phrase as its complement.

A preposition together with its complement is called a prepositional phrase.

Examples are in England, under the table, after six pleasant weeks, between the land and the sea.

A prepositional phrase can be used as a complement or post-modifier of a noun in a noun phrase, as in the man in the car, the start of the fight; as a complement of a verb or adjective, as in deal with the problem, proud of oneself; or generally as an adverb phrase.

English allows the use of "stranded" prepositions. This can occur in interrogative and relative clauses, where the interrogative or relative pronoun that is the preposition's complement is moved to the start (fronted), leaving the preposition in place. This kind of structure is avoided in some kinds of formal English.

For example:

• What are you talking about? (Possible alternative version: About what are you talking?)
• The song that you were listening to ... (more formal: The song to which you were listening ...)

Notice that in the second example the relative pronoun that could be omitted.

Stranded prepositions can also arise in passive voice constructions and other uses of passive past participial phrases, where the complement in a prepositional phrase can become zero in the same way that a verb's direct object would: it was looked at; I will be operated on; get your teeth seen to.

The same can happen in certain uses of infinitive phrases: he is nice to talk to; this is the page to make copies of.

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.

Collocations

Collocations are combinations of words that are frequently used together in a particular order, forming a natural-sounding expression. These word pairs or groups often sound more natural to native speakers than other possible combinations of the same words. Understanding collocations is important for language learners because they help you sound more fluent and natural when speaking or writing.

Vocabulary

Vocabulary in English language can be thought of as a toolbox that you use to express yourself and understand others. It's important to continue expanding and refining it. This means learning new words, phrases, and idiomatic expressions and understanding how to use them in different contexts. The more tools you have in your toolbox, the more effectively you can communicate and understand others. Having a broad vocabulary also allows you to understand and engage with more complex texts and ideas, giving you access to new information and opportunities. Additionally, having a strong vocabulary is essential for academic and professional success, as it allows you to express yourself clearly and persuasively in writing and speaking. Like a carpenter who continues to learn new tools and techniques to improve their craft, expanding your vocabulary is an ongoing process that will help you improve your communication skills.

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 voice — The report was written yesterday.
• Modal verbs — You should apply early. / She might be late.
• Used to — I 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.

B2 | Upper Intermediate

B2, or Upper Intermediate, is the fourth level on the CEFR scale. It marks the point where you move from "getting by" to genuinely comfortable communication — handling complex topics, expressing nuanced opinions, and understanding most of what you read or hear in real-world contexts.

What a B2 user can do

At this level, you're expected to:

• Understand complex texts on both concrete and abstract topics, including technical discussions in your own field.
• Follow extended speech and lectures, even when the structure isn't entirely clear, as long as the topic is reasonably familiar.
• Interact fluently and spontaneously enough that conversations with native speakers flow naturally — without strain on either side.
• Produce clear, detailed text on a wide range of subjects, using connectors and cohesive devices to build well-structured arguments.
• Explain and defend a viewpoint on a topical issue, weighing the advantages and disadvantages of different options.
• Recognize implicit meaning — reading between the lines in demanding, longer texts.

What B2 grammar looks like in practice

B2 is where grammar stops being about isolated rules and starts being about flexibility and precision. You're expected to control structures like:

• Advanced conditionals and mixed conditionals — moving beyond simple if-clauses to express hypothetical and counterfactual meaning.
• Passive voice in varied tenses and contexts, not just present and past simple.
• Reported speech with correct sequence of tenses, including backshifting and reporting verbs.
• Participle clauses and the distinction between participles and gerunds.
• Comparative and superlative structures beyond basic -er/-est, including double comparatives and qualifying expressions.

Errors still happen at B2, but they rarely cause misunderstanding. The goal is controlled, flexible use of language across social, academic, and professional settings.

How B2 fits in the CEFR progression

B2 builds directly on the foundations of B1 (Intermediate) and prepares you for C1 (Advanced). Many university entrance exams, professional certifications, and immigration requirements target B2 as the minimum standard.

Self-check: If you can read a newspaper editorial, follow most of a TED talk without subtitles, and write a clear essay arguing a position — you're likely operating at B2.
