English grammar is simply the set of patterns that tell us how to put words together so that meaning is clear. You do not need to learn it all at once. The most efficient way to study is to take one topic at a time, understand the core pattern, look at a handful of examples, and then practise until the structure feels automatic. This guide is organised exactly that way: fifteen major grammar areas, each explained in plain English, each linking down to a dedicated topic page and a relevant interactive exercise where you can apply what you have just read.
Throughout the guide you will see buttons that take you to focused practice. Reading about grammar builds understanding, but active recall — retrieving the rule and using it in a quiz, a cloze, or a sentence-building task — is what moves grammar from short-term memory into permanent fluency. Use the table of contents above to jump to any area, or read straight through for a complete tour of English grammar.
Area 1Verb Tenses
Tenses are the backbone of English. They combine three times — past, present and future — with four aspects (simple, continuous, perfect and perfect continuous) to produce twelve forms in total. In practice, learners rely on a smaller core: the present simple for habits and facts, the present continuous for actions happening now, the past simple for finished events, the present perfect for experiences and recent news, and a couple of future forms for plans and predictions.
The classic difficulty is choosing between the past simple and the present perfect. Use the past simple when the time is finished and definite (yesterday, last year, in 2019) and the present perfect when the past action still matters now or the time period is unfinished. Start with the present simple, then build up through the past and the present perfect before tackling future forms.
Area 2Articles — a, an, the
Articles are tiny words that cause big trouble, especially for learners whose first language has no articles. Use a or an (the indefinite articles) for a singular countable noun mentioned for the first time or when it is not specific. Use the (the definite article) when both speaker and listener know exactly which thing is meant. Use no article at all for plural and uncountable nouns spoken about in general.
Choose an before a vowel sound (an hour, an MP) and a before a consonant sound (a university, a euro). Mastering articles is one of the fastest ways to make your English sound more natural.
Area 3Prepositions
Prepositions show relationships of time, place and direction: in, on, at, by, for, with, to, from and many more. They have few firm rules, so they are best learned in chunks and fixed phrases. For time, a useful guideline is at for clock times, on for days and dates, and in for months, years and longer periods. For place, at points to a spot, on to a surface, and in to an enclosed space.
Many verbs and adjectives pair with a specific preposition (depend on, good at, interested in, afraid of). Learning these dependent prepositions as whole phrases saves you from guessing.
Area 4Conditionals
Conditionals are if-sentences that describe the result of a condition. There are four main types. The zero conditional states general truths (If you heat ice, it melts). The first conditional describes real future possibilities (If it rains, I will stay home). The second conditional imagines unreal or unlikely present situations (If I won the lottery, I would travel). The third conditional talks about imaginary pasts (If I had studied, I would have passed).
Conditionals are highly valued in exams because they show grammatical range. Master the verb form in each clause and you can express possibility, advice and regret with precision.
Area 5Modal Verbs
Modal verbs — can, could, may, might, must, shall, should, will, would — add meaning about ability, possibility, permission, obligation and advice. They are followed by the base form of the verb (no to) and do not change for the third person: she can, not she cans.
Subtle differences matter: must is stronger than should; may and might express possibility with slightly different degrees of certainty. Using modals accurately makes your English more polite, precise and natural.
Area 6Passive Voice
The passive voice shifts attention from who does an action to the action itself or to what receives it. Form it with the correct tense of be + the past participle. Use it when the doer is unknown, unimportant, or obvious, and especially in formal, academic and scientific writing.
The passive exists across all tenses (is made, was made, has been made, will be made). It is a key marker of advanced writing and a frequent feature of IELTS and Cambridge tasks.
Area 7Reported Speech
Reported (or indirect) speech tells someone what another person said without quoting them word for word. When the reporting verb is in the past, the tense usually shifts back one step: present becomes past, past becomes past perfect, will becomes would, and so on. Pronouns and time expressions also change to fit the new viewpoint.
Reported speech also covers reported questions, commands and requests. It is essential for retelling conversations, writing summaries, and sounding fluent in both speech and writing.
Area 8Relative Clauses
Relative clauses add information about a noun using relative pronouns: who (people), which (things), that (people or things), where (places), when (times) and whose (possession). Defining relative clauses identify which person or thing we mean and take no commas. Non-defining clauses add extra, non-essential detail and are separated by commas.
Relative clauses let you combine short sentences into richer, more sophisticated ones — a hallmark of higher-level writing.
Area 9Gerunds & Infinitives
A gerund is the -ing form of a verb used as a noun (swimming, reading); an infinitive is the base form with to (to swim, to read). Some verbs are followed by a gerund (enjoy, finish, avoid), some by an infinitive (want, decide, hope), and a few by either, sometimes with a change in meaning.
There is no single rule for which verbs take which form, so the most reliable approach is to learn common verb patterns through repeated practice.
Area 10Comparatives & Superlatives
Comparatives compare two things; superlatives single out one from a group. Short adjectives add -er and -est (tall → taller → the tallest); longer adjectives use more and the most (interesting → more interesting → the most interesting). A handful are irregular (good → better → the best; bad → worse → the worst).
Remember to use than after a comparative and the before a superlative. These forms appear constantly in everyday descriptions and opinion writing.
Area 11Imperative Sentences
The imperative mood gives commands, instructions, requests and advice. It is formed with the bare infinitive — no subject pronoun is needed because the subject is always the person being addressed (you, implied). Add please or a softening modal to make an imperative more polite, and do not (or don't) to make it negative.
Imperatives are used constantly in everyday English: recipe instructions, road signs, classroom directions and public notices all rely on this simple but powerful form. At A2–B1 level, mastering imperatives lets you give and follow instructions clearly and confidently.
Area 12Quantifiers
Quantifiers tell us how much or how many of something there is. Some work only with countable nouns (many, few, a few, several), others only with uncountable nouns (much, little, a little), and some work with both (some, any, a lot of, plenty of, no). Choosing the right quantifier is closely linked to understanding the countable/uncountable distinction.
Questions and negatives typically use any instead of some (Is there any milk? There isn't any left). Selecting the correct quantifier — especially distinguishing few (negative feeling) from a few (positive feeling) — is a hallmark of B1–B2 accuracy.
Area 13Wish & If Only
Both wish and if only express regret about the present or past, or a desire for something to be different. For present situations you feel are unlikely or impossible, use wish + past simple (I wish I spoke French). For past regrets, use wish + past perfect (I wish I had studied harder). If only adds extra emotional emphasis to either context.
These structures are closely related to conditional clauses and use the same backshifted tenses. Mastering wish and if only is essential for B2–C1 speakers who want to discuss hypothetical situations and express nuanced feelings about past events.
Area 14Participle Clauses
Participle clauses use the present participle (-ing) or past participle (-ed / irregular) to shorten and combine sentences. They are common in formal written English because they allow writers to add information efficiently without repeating the subject. A participle clause shares its subject with the main clause.
Participle clauses can express time (Having finished dinner, they left), reason (Not knowing the answer, he stayed silent), and condition or concession. They are a key feature of C1 writing and a reliable way to demonstrate high grammatical range in academic and professional contexts.
Area 15Cleft Sentences & Emphasis
Cleft sentences split a single piece of information into two clauses in order to emphasise one particular element. The two main types are it-clefts (It was Maria who found the key) and what-clefts, also called pseudo-clefts (What surprised us was the result). Both allow a speaker or writer to highlight information that might otherwise be lost in a normal sentence.
Other emphasis devices include fronting (Rarely have I seen such skill), inversion after negative adverbials, and do-emphasis in affirmative sentences (I do appreciate your help). These structures give spoken and written English rhetorical power and are especially valued at B2–C1 level in exams and academic writing.
