English Essential grammar

Abbreviations used in this guide

Each example below has three parts: the original text, a literal gloss describing how every word works, and a natural translation. The glosses use a few shorthand labels so they stay short. Don't worry about memorising them: this is a reference you can come back to.

Person and number · 1sg / 2sg / 3sg: first / second / third person singular (I, you, he/she/it) · 1pl / 2pl / 3pl: first / second / third person plural (we, you-all, they)

Gender and case · m / f / n: masculine / feminine / neuter · sg / pl: singular / plural · m.sg: combined: masculine singular (and similarly f.pl, n.sg, etc.) · NOM / ACC / GEN / DAT / INS / LOC: grammatical cases (nominative/accusative/genitive/dative/instrumental/locative): which role the word plays in the sentence

Tense and aspect · PRES: present · PRET: preterite (a finished past event) · IMPF: imperfect (an ongoing or habitual past situation) · FUT: future · PERF: perfect (an action completed with present relevance) · PROG: progressive (action in progress, e.g. am eating) · COND: conditional (would…)

Mood · IND: indicative (regular statement) · SUBJ: subjunctive (uncertainty, wishes, doubts) · IMP: imperative (commands) · INF: infinitive (dictionary form: to go, to eat)

Other · REFL: reflexive (action on oneself: myself, yourself) · PERS: personal a (Spanish only: marks a human direct object) · HON: honorific (extra-polite form, common in Japanese/Korean) · TOP / SUB / OBJ: topic / subject / object markers (Japanese, Korean) · CL: classifier (Chinese, Japanese, Korean: a counter word for nouns) · NEG: negation

Word order

English follows a strict Subject + Verb + Object (SVO) order. Unlike many languages, you cannot move words around freely: the position of a word usually tells you its role in the sentence. Time and place expressions normally go at the end of the sentence, or sometimes at the very beginning, but rarely in the middle. Adverbs of manner (how) usually follow the object. Because English has almost no case endings, word order is the main way to know who is doing what to whom. Compare: The dog bites the man vs. The man bites the dog.

  • I read a book. — Subject + Verb + Object
  • She drinks coffee in the morning. — S + V + O + Time
  • We study English at home every day. — S + V + O + Place + Time

Articles

English has two articles. The indefinite article a / an (singular only) introduces something for the first time or any one of a kind. Use a before consonant sounds and an before vowel sounds: a book, an apple, a university (sounds like yu-), an hour (silent h). The definite article the refers to something specific or already known. Omit articles with most plurals and uncountable nouns when speaking in general: Dogs are friendly, I like music. Also omit before most proper names, languages, meals, and many places: I speak English, She is at home.

  • I have a cat. The cat is black. — a = new; the = known
  • She eats an apple every day. — an + vowel sound
  • Water is important. — no article (general / uncountable)

Pronouns

English pronouns change form by role, not by gender (except he/she/it). Subject (before verb): I, you, he, she, it, we, they. Object (after verb or preposition): me, you, him, her, it, us, them. Possessive adjective (before a noun): my, your, his, her, its, our, their. Possessive pronoun (stands alone): mine, yours, his, hers, ours, theirs. You is the same for singular and plural, formal and informal. It is used for things, animals, and weather. The subject pronoun is almost always required: you cannot drop it as in Spanish or Italian.

  • She loves him. — Subject + Verb + Object pronoun
  • This is my book. That book is yours. — possessive adj. vs. possessive pron.
  • It is raining. — dummy it for weather

Verb conjugation

English verbs barely change. In the present simple, regular verbs add only -s in the third person singular (he/she/it); all other persons use the base form. to be is the most irregular: I am, you are, he/she/it is, we/you/they are. to have: I/you/we/they have, he/she/it has. to do: I/you/we/they do, he/she/it does. Spelling rules for the -s ending: verbs ending in -s, -sh, -ch, -x, -o add -es (goes, watches); verbs ending in consonant + y change to -ies (study → studies).

  • I work, you work, he works, we work. — only 3rd sing. changes
  • She is a teacher and has two children. — to be / to have, 3rd sing.
  • He goes to school. — go → goes (-es after -o)

Present tense

There are two present tenses. The present simple describes habits, routines, facts, and permanent states: Subject + base verb (+ -s for 3rd sing.). Common signals: every day, always, usually, never. The present continuous (or progressive) describes actions happening right now or temporary situations: Subject + am/is/are + verb-ing. Common signals: now, right now, at the moment, today. Some verbs (called stative) are rarely used in the continuous: know, like, want, need, believe, understand. Use the simple instead: I know him (not I am knowing him).

  • I drink coffee every morning. — present simple: habit
  • I am drinking coffee now. — present continuous: action now
  • She works in Madrid, but this week she is working in Rome. — permanent vs. temporary

Past tense

The past simple describes finished actions at a definite past time. Regular verbs add -ed (work → worked, play → played). Many common verbs are irregular and must be memorized (go → went, see → saw, eat → ate, have → had). The form is the same for all persons. Common signals: yesterday, last week, in 2020, ago. The present perfect (have/has + past participle) connects the past with the present: an action with a result now, or an experience without a specific time. Common signals: ever, never, already, yet, just, since, for.

  • I worked yesterday. — past simple: finished time
  • She went to Paris last year. — irregular past simple
  • I have lived here for five years. — present perfect: past until now

Future tense

English has no single future tense; it uses auxiliaries. will + base verb is used for predictions, instant decisions, promises, and general future facts: It will rain tomorrow. be going to + base verb is used for plans already decided and for predictions based on present evidence: I am going to study tonight. Both are often interchangeable in everyday speech, but will feels more spontaneous, while going to feels more planned. Negative: will not / won't, am/is/are not going to. The present continuous can also express scheduled future plans: I am meeting John on Friday.

  • I will help you. — will: offer / decision now
  • I am going to visit my parents next week. — going to: planned future
  • Look at those clouds: it is going to rain. — going to: present evidence

Essential pattern: present-tense paradigm (subject + base, 3rd-sg -s)

English present-tense conjugation is famously minimal. For almost every regular verb, the form is identical to the dictionary base in all persons except the third-person singular (he / she / it / a name / a singular thing), where you add -s (or -es after -s, -sh, -ch, -x, -o, and -ies after consonant + y). The pronoun is obligatory: English does not drop it (Speaks French is not a sentence).

PersonPronounto work (regular)to go (regular spelling)to study (y→ies)
1sgIworkgostudy
2sgyouworkgostudy
3sghe / she / itworksgoesstudies
1plweworkgostudy
2plyouworkgostudy
3pltheyworkgostudy

**Contractions and the auxiliary do.** In statements you usually drop the auxiliary, but it returns in questions and negatives: Do you work? / She doesn't work. The verbs be, have, and do themselves are irregular: I am / you are / he is, I have / he has, I do / he does. Spoken English contracts them heavily: I'm, you're, he's, she's, it's, we're, they're; I've, you've, he's (= he has), they've; don't, doesn't.

Use it for habits, routines, general truths, scheduled events, and stative meanings (I live in Rome. Water boils at 100°C. The train leaves at six. I know her.). For something happening right now, switch to the progressive (next sections).

Pitfalls. Forgetting the 3rd-sg -s is the single most common error (She speak English: wrong; She speaks English). Adding -s to other persons is also wrong (I works: wrong). With stative verbs (know, want, need, like, believe, understand, own), don't use the progressive: say I want coffee, not I am wanting coffee.

  • I work from home; my sister works in a hospital. — base vs. 3sg -s in the same sentence
  • He goes to the gym every morning and studies at night. — -es after -o; y→ies after consonant
  • Do you speak Spanish?: No, I don't, but my husband does. — auxiliary do/does in question, negative, and short answer
  • She doesn't like coffee, she prefers tea. doesn't + base (NOT doesn't likes)
  • We live in Madrid. They live in Lisbon. — plural subjects keep the base form
  • The shop opens at nine and closes at eight. — scheduled / habitual present

Essential pattern: am/is/are + verb-ing (present progressive)

The present progressive (also called present continuous) describes an action in progress right now, a temporary situation around now, or a definite future arrangement. The formula is always subject + am/is/are + verb-ing.

PersonPronounbe-ing form
1sgIam ('m)working / eating / going
2sgyouare ('re)working / eating / going
3sghe / she / itis ('s)working / eating / going
1plweare ('re)working / eating / going
2plyouare ('re)working / eating / going
3pltheyare ('re)working / eating / going

Spelling of the -ing form. Drop silent final -e (write → writing, take → taking). Double a final single consonant after a single stressed vowel (run → running, sit → sitting, begin → beginning). Final -ie becomes -y (lie → lying, die → dying).

Common uses. - Right now: I'm reading. - Around this period (not necessarily this second): She's learning Korean this year. - Trend / change: The weather is getting warmer. - Annoying habit with always: He's always losing his keys! - Planned future: We're flying to Tokyo on Monday.

Negative and question. I'm not working. / Are you working? / Why is she crying?

Pitfalls. Don't drop be (I working now: wrong; I'm working now). Don't use the progressive with stative verbs: want, know, need, like, love, hate, prefer, believe, mean, seem, own, belong, hear, see (perceive). I am wanting a coffee is wrong: say I want a coffee. Note that some verbs are both stative and active with different meanings: I think you're right (opinion: simple) vs. I'm thinking about it (mental process: progressive).

  • I'm cooking dinner: can you call me back later? — action in progress right now
  • She is studying medicine at university. — temporary, around this period
  • What are you doing this weekend?: We're visiting my parents. — planned future arrangement
  • It's raining and the wind is getting stronger. — two progressives: now + change
  • He's always interrupting me! — always + -ing: irritation
  • I don't understand. (NOT *I'm not understanding.*) — stative verb: use simple, not progressive

Essential pattern: want to + base verb

Want expresses desire. Followed by another verb, the structure is want + to + base verb (an infinitive). Want itself takes the normal regular present-tense forms (want / wants), and the second verb stays in its base form forever: no -s, no -ing, no -ed.

PersonPronounwant+ to + base
1sgIwantto go / to eat / to learn
2sgyouwantto go / to eat / to learn
3sghe / she / itwantsto go / to eat / to learn
1plwewantto go / to eat / to learn
2plyouwantto go / to eat / to learn
3pltheywantto go / to eat / to learn

You can also use want with a direct object (no second verb): I want a coffee. She wants a new car. And with an object + infinitive for what you want someone else to do: I want you to listen. She wants him to call her.

Negative and question. Use do/does: Do you want to come? / She doesn't want to talk about it. Past tense: wanted (regular).

Register. Want is direct and neutral: fine among friends and family. For requests in shops, restaurants, or with strangers, it can sound blunt; switch to would like (see next sections) or Could I have…?

Pitfalls. Never I'm wanting: want is stative (see progressive section). Don't drop to: I want learn English is wrong; the correct form is I want to learn English. Don't conjugate the second verb: He wants to eats is wrong: only want changes, not the infinitive.

  • I want to learn three languages this year. — want + to + base
  • She wants to become a doctor. — 3sg wants + to + base
  • What do you want to do tonight?: I want to stay home and watch a film. — conversational Q + A
  • We don't want to be late, let's go now. — negative with don't want to
  • My parents want me to study law, but I want to study music. — want + object + to + base (controlling another subject)
  • Do you want a coffee or some tea? want + direct object (no second verb)

Essential pattern: would like + to + base (polite want)

Would like is the polite version of want. Use it with strangers, in shops, restaurants, hotels, formal emails, and any time you want to sound considerate rather than blunt. Structure: subject + would like + to + base verb (or + direct object). Would is a modal, so the form is the same for every person: no -s in the third singular.

PersonPronounwould like+ to + base / + noun
1sgIwould like ('d like)to order / a table / some water
2sgyouwould like ('d like)to order / a table / some water
3sghe / she / itwould like ('d like)to order / a table / some water
1plwewould like ('d like)to order / a table / some water
2plyouwould like ('d like)to order / a table / some water
3pltheywould like ('d like)to order / a table / some water

Contraction. I would → I'd; same for you'd, he'd, she'd, we'd, they'd. In speech the 'd often blurs into the next word.

Questions and negatives. Would you like to join us? / Would you like some water? / I wouldn't like to live in a big city. The question Would you like…? is the standard polite offer: much friendlier than Do you want…?

**Compare with like.** I like coffee = general taste (I enjoy coffee). I'd like a coffee = right now, please give me one. The two are completely different: don't say I like a coffee when ordering.

Pitfalls. No -s on would (she would likes: wrong). Don't drop to before the verb (I'd like order a pizza: wrong; correct: I'd like to order a pizza). When followed by a noun, no to: I'd like a beer, not I'd like to a beer.

  • I'd like to book a table for two, please. — polite request in a restaurant
  • Would you like to come to my birthday party? — polite invitation
  • She would like to speak to the manager. — 3sg: no -s on would
  • Would you like some help with that suitcase? — polite offer (note the noun, no to)
  • We'd like to thank everyone for coming. — formal speech opening
  • What would you like to drink?: I'd like a glass of red wine, please. — conversational Q + A at a restaurant

Essential pattern: be going to + base (planned future)

Be going to + base verb expresses a planned, intended, or evidence-based future. Use it for decisions already made before the moment of speaking (I'm going to call her tonight: I decided this morning) and for predictions you can see coming (Look at the sky: it's going to rain). Structure: subject + am/is/are + going to + base verb.

PersonPronounbegoing to + base
1sgIam ('m)going to leave / study / travel
2sgyouare ('re)going to leave / study / travel
3sghe / she / itis ('s)going to leave / study / travel
1plweare ('re)going to leave / study / travel
2plyouare ('re)going to leave / study / travel
3pltheyare ('re)going to leave / study / travel

**Compare with will.** Will is for spontaneous decisions (The phone's ringing: I'll get it!), promises, predictions without visible evidence, and offers. Be going to is for prior plans and evidence-based predictions. I'm going to study tonight (already decided) vs. I'll help you (deciding right now).

Informal speech. In casual speech, going to + verb often blurs into gonna (I'm gonna call you later). Write it as going to in anything but very casual dialogue. Gonna is never used before a noun: I'm going to the gym: never I'm gonna the gym.

Negative and question. I'm not going to argue with you. / Are you going to apply for the job? / What is she going to wear?

Pitfalls. Don't say I'm going to going: drop go: just I'm going to the party (movement) or I'm going to + verb (future). Don't omit be: I going to leave is wrong; correct: I'm going to leave.

  • I'm going to start a new job next month. — planned future: decision already made
  • Look out: that glass is going to fall! — prediction based on present evidence
  • What are you going to do after you graduate? — wh- question about plans
  • She's going to have a baby in July. — scheduled future event
  • We're not going to wait any longer; let's order. — negative: abandoning a plan
  • I'm gonna grab a coffee: want one? — informal gonna in casual speech

Essential pattern: will + base (modal future)

Will is the simplest future marker: subject + will + base verb. As a modal, will never changes form: no -s in the third person, no to after it. Use it for: - Spontaneous decisions at the moment of speaking: The doorbell: I'll get it. - Predictions (especially without visible evidence): AI will change everything. - Promises and offers: I'll always love you. I'll help you carry that. - Future facts: The match will start at 9 p.m.

PersonPronounwill+ base
1sgIwill ('ll)go / call / try
2sgyouwill ('ll)go / call / try
3sghe / she / itwill ('ll)go / call / try
1plwewill ('ll)go / call / try
2plyouwill ('ll)go / call / try
3pltheywill ('ll)go / call / try

Contractions. I'll, you'll, he'll, she'll, it'll, we'll, they'll; negative will not → won't (note the spelling: not willn't).

Question. Invert: Will you marry me? / When will the meeting end? In requests, Will you…? sounds direct (Will you close the door?); Would you…? is more polite (Would you close the door, please?).

**Compare with going to.** I'll call her later (decided now) vs. I'm going to call her later (already planned). Both are correct in many contexts; the choice signals when the decision was made.

Pitfalls. Don't put to after will (I will to go: wrong; I will go). Don't conjugate (She wills go: wrong; She will go). With if-clauses, use the present, not will, in the if-part: If it rains, I will stay home (NOT If it will rain).

  • Don't worry, I'll do it for you. — spontaneous offer
  • She'll be thirty next week. — future fact
  • I think it will snow tomorrow. — prediction (no visible evidence)
  • I promise I won't tell anyone. — promise + negative won't
  • Will you be at the meeting?: Yes, I will. — yes/no question and short answer
  • If you study hard, you'll pass the exam. if + present, main clause with 'll

Essential pattern: can / could + base (ability, possibility, permission)

Can is the modal for present ability, possibility, permission, and informal requests. Could is its past counterpart for past ability, and also a more polite / hypothetical version in the present. Structure: subject + can/could + base verb: no to, no -s in 3rd person.

PersonPronouncan / could+ base
1sgIcan / couldswim / drive / help
2sgyoucan / couldswim / drive / help
3sghe / she / itcan / couldswim / drive / help
1plwecan / couldswim / drive / help
2plyoucan / couldswim / drive / help
3pltheycan / couldswim / drive / help

**Uses of can.** - Ability: I can speak three languages. - Possibility: It can get cold here in summer. - Permission: You can leave early today. - Informal request: Can you pass the salt?

**Uses of could.** - Past ability (general): When I was a child, I could run for hours. (For a specific past achievement, use was/were able to or managed to.) - Polite request: Could you help me with this? (more polite than can) - Possibility / suggestion: We could go to the cinema tonight. - Hypothetical: If I had more time, I could learn the guitar.

Negative. cannot / can't (written as one word) and could not / couldn't.

For other tenses, English uses be able to: I have been able to / I will be able to / I was able to. Can itself has no infinitive or -ing form.

Pitfalls. No to after can/could (I can to swim: wrong; I can swim). No -s in 3rd sg (She cans dance: wrong; She can dance). Don't confuse could (past or polite) with would (hypothetical desire): Could you = Are you able to?; Would you = Are you willing to?

  • I can ride a bike but I can't drive a car. — present ability: affirmative and negative
  • Could you repeat that, please? — polite request
  • When I was younger, I could read for hours without getting tired. — past ability (general)
  • We could meet on Friday if you're free. — suggestion / possibility
  • Can I borrow your pen?: Sure, you can keep it. — informal request + permission
  • She can't come to the phone right now; she's in a meeting. — negative: current impossibility

Essential pattern: have/has + past participle (present perfect)

The present perfect links a past action to now. Structure: subject + have/has + past participle. Use it when the time is unspecified (or the action continues / has present relevance), not when you mention a finished past time like yesterday or in 2020 (those need the past simple).

PersonPronounhave/has+ past participle
1sgIhave ('ve)worked / gone / seen / eaten / been
2sgyouhave ('ve)worked / gone / seen / eaten / been
3sghe / she / ithas ('s)worked / gone / seen / eaten / been
1plwehave ('ve)worked / gone / seen / eaten / been
2plyouhave ('ve)worked / gone / seen / eaten / been
3pltheyhave ('ve)worked / gone / seen / eaten / been

Past participles. For regular verbs, the past participle is the same as the past simple: just add -ed (work → worked → worked). Many common verbs are irregular and must be memorized: sample three-form list (base / past / past participle): go / went / gone; see / saw / seen; eat / ate / eaten; do / did / done; take / took / taken; write / wrote / written; be / was, were / been; have / had / had; make / made / made; come / came / come.

Common uses and signals. - Life experience: Have you ever been to Japan? - Recent past with present result: I've lost my keys (= and I still can't find them). - Unfinished period: I haven't seen him today. (today isn't over) - With for / since: I've lived here for five years / since 2021. - With just, already, yet: She's just arrived. We've already eaten. Have you finished yet?

Pitfalls. Have went is wrong: the past participle of go is gone (I have gone). He have is wrong: third singular is has (He has gone). Don't use the present perfect with finished past times: I have seen him yesterday is wrong; say I saw him yesterday (past simple) or I have seen him (no time) or I have seen him this week (unfinished period). Been vs. gone: She has been to Paris (and is back) vs. She has gone to Paris (still there).

  • I've lived in this city for ten years. — for + duration: unfinished period
  • Have you ever eaten sushi?: Yes, I have, many times. — life experience question + short answer
  • She has just finished her homework. just: very recent past
  • We haven't seen that film yet. yet in a negative: expected to happen
  • He has gone to the supermarket; he'll be back soon. gone: still there
  • They have been married since 2015. — since + point in time

Negation

To make a sentence negative, you almost always need an auxiliary verb plus not. With to be, just add not: I am not tired. With most other verbs in the present simple, use do not / does not + base verb: I do not (don't) know, She does not (doesn't) like fish. In the past simple, use did not (didn't) + base verb for all persons: We didn't go. With modal verbs (can, will, should), add not directly: cannot/can't, won't, shouldn't. Note: do not double-negate in standard English: say I don't know anything, not I don't know nothing.

  • I am not hungry. — be + not
  • He doesn't speak French. — does + not + base verb
  • We didn't see her yesterday. — did + not + base verb (past)

Questions

Yes/no questions are formed by putting an auxiliary verb before the subject. With to be: Are you tired? With other verbs in the present, use do/does + subject + base verb: Do you speak English? Does she live here? In the past, use did + subject + base verb: Did they arrive? Wh- questions start with a question word (what, where, when, who, why, how, which) followed by the same auxiliary + subject + verb pattern: Where do you live? When the wh- word is the subject, keep normal order with no auxiliary: Who called?

  • Are you a student? — be + subject (yes/no)
  • Do you like coffee? — do + subject + base verb
  • Where does he work? — wh- + does + subject + base verb

Plural of nouns

Most nouns form the plural by adding -s: book → books, car → cars. Nouns ending in -s, -ss, -sh, -ch, -x, -z add -es: bus → buses, box → boxes, watch → watches. Nouns ending in consonant + y change y to -ies: city → cities, baby → babies. Many nouns ending in -f / -fe change to -ves: leaf → leaves, knife → knives. Some common nouns are irregular: man → men, woman → women, child → children, foot → feet, tooth → teeth, mouse → mice, person → people. A few are unchanged: fish, sheep, deer. Uncountable nouns (water, information, advice) have no plural form.

  • one book, two books — regular -s
  • one city, three cities — y → ies
  • one child, many children — irregular plural

Adjectives

English adjectives never change form: no agreement with gender or number: a tall boy, tall girls, tall trees. Adjectives normally come before the noun they describe: a red car, an interesting book. They can also come after the verb to be and similar linking verbs (seem, look, become, feel): The car is red. When you use several adjectives together, the typical order is: opinion + size + age + shape + colour + origin + material + purpose + noun: e.g. a beautiful small old round red Italian wooden table. In practice, two or three adjectives are usually enough.

  • a big house — adjective before noun
  • The house is big. — adjective after be
  • two small black cats — no plural agreement on adj.

Adverbs of frequency

Adverbs of frequency tell how often something happens: always (100%), usually, often, sometimes, rarely / seldom, never (0%). Their position is fixed: they go before the main verb but after the verb to be and after auxiliary verbs. I always drink tea. She is always late. They have never been to Japan. Longer time expressions like every day, once a week, twice a month, from time to time usually go at the end (or beginning) of the sentence: I go running every day. Do not put one-word frequency adverbs at the end of the sentence in standard English.

  • I always wake up at seven. — adv. before main verb
  • He is never angry. — adv. after be
  • We play tennis twice a week. — long expression at end

Special features

Three features shape much of English grammar. (1) Auxiliary verbs: do/does/did, have/has/had, be (am/is/are/was/were) are used to build questions, negatives, and compound tenses. They carry the tense and the not, so the main verb stays in its base form: Did you see?, She hasn't arrived. (2) No grammatical gender: nouns are neutral; only he/she/it mark a real-world distinction (people vs. things). Adjectives and articles don't change. (3) Modal verbs (can, could, may, might, must, should, will, would) are followed by the **base verb without *to***: I can swim, You should rest, She must go. They have no -s in the third person.

  • Do you know the answer? — auxiliary do forms the question
  • The book is on the table. It is heavy. it: no gender for objects
  • You can come tomorrow. — modal + base verb, no to
