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

To practice these, try Comparatives and Superlatives. You can also build a foundation with Basics. Adjectives and Adverbs. and Basics. Word Order..

Gerund

The gerund takes the same form (ending in -ing) as the present participle, but is used as a noun (or rather the verb phrase introduced by the gerund is used as a noun phrase). Many uses of gerunds are thus similar to noun uses of the infinitive. Uses of gerunds and gerund phrases are illustrated below:

As subject or predicative expression:

• Solving problems is satisfying.
• My favorite activity is spotting butterflies.

As object of certain verbs that admit such constructions:

• I like solving problems.
• We tried restarting the computer.

In a passive-type construction after certain verbs, with a gap (zero) in object or complement position, understood to be filled by the subject of the main clause:

• That floor wants/needs scrubbing.
• It doesn't bear thinking about.

As complement of certain prepositions:

• No one is better at solving problems.
• Before jogging, she stretches.
• After investigating the facts, we made a decision.
• That prevents you from eating too much.

It is considered grammatically correct to express the agent(logical subject) of a gerund using a possessive form (they object to my helping them), although in informal English a simple noun or pronoun is often used instead (they object to me helping them).

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.

Subject

The subject is the part of a sentence or clause that tells you who or what the sentence is about. It typically comes before the verb and controls the verb's form — meaning the verb must agree with the subject in number and person.

How to identify the subject

The subject is usually a noun, pronoun, or noun phrase that performs the action or is described by the predicate.

• She works at a hospital.
• The old bridge collapsed during the storm.
• Running every morning keeps me healthy.

The verb agrees with the subject: She works (singular) vs. They work (plural). This subject-verb agreement is one of the most reliable ways to find the subject.

Self-check trick: Ask "Who or what + verb?" to locate the subject. "Who works at a hospital?" → She. That's your subject.

Types of subjects

• Simple subject — the core noun or pronoun alone: Dogs bark.
• Complete subject — the simple subject plus all its modifiers: The two large dogs next door bark every night.
• Compound subject — two or more subjects joined by a conjunction: Coffee and tea are available.

Tricky cases

Sometimes the grammatical subject isn't the "doer." In passive sentences, the subject receives the action:

• ❌ Thinking the subject must be the doer: "The window" broke itself?
• ✅ The window was broken by a ball. (The window is the subject, but the ball did the breaking.)

English also uses dummy subjects — words like it or there that fill the subject position without carrying real meaning:

• It is difficult to learn French.
• There are three problems with this plan.

In the first example, the "real" subject (the thing that is difficult) is to learn French, but grammatically it holds the subject slot. These are sometimes called expletive subjects.

Why it matters

Getting the subject right is essential for subject-verb agreement, choosing correct pronoun forms (he vs. him), and building clear sentences. Misidentifying the subject is one of the most common sources of grammar errors, especially with longer or inverted sentences.

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.

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...).

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.
