/ˈɪŋ.ɡlɪʃ/  ·  noun  ·  West Germanic language

A language built from a small set of moving parts — a handful of word classes, a strict word order, and a limited set of tense patterns — that combine into everything from a shopping list to a court ruling. This guide walks through those parts in order, from the ten words you'll use in almost every sentence, to the eight hundredth you'll need for a graduate seminar.

Use the tabs on the left (top, on mobile) to move between sections. Grammar is organized into three stages; the word bank underneath holds 1,000 words sorted from the ten most frequent words in the language up through specialist, literary vocabulary — searchable, filterable, and tagged by part of speech.

How this guide works

English proficiency is really three skills stacked on top of each other: knowing enough words to say something, knowing enough grammar to arrange them correctly, and having practiced enough to do both without thinking. This guide is organized to build all three at once.

1Grammar, in three stages

Grammar Basics covers what you need to form a correct, simple sentence: word order, articles, pronouns, the verb "to be," present tense, and basic questions.

Building Blocks covers the tenses and structures that let you talk about the past, the future, obligation, and comparison — the grammar of everyday fluency.

Advanced Grammar covers the structures that separate a competent speaker from a precise one: the passive voice, conditionals, reported speech, and the subtler tools of formal and academic writing.

2The 1,000-word bank

Vocabulary is ordered by how often a word actually appears in English, moving from function words like the and of through everyday nouns and verbs, into the vocabulary of work, study, and technology, and finally into the more exact, formal, and literary vocabulary used in academic and professional writing.

Each entry is tagged with its part of speech and its level (1 = most frequent, 10 = most specialized), and the whole list is searchable.

3A rough proficiency map

StageWord levelsYou can
Beginner (A1)1–2Introduce yourself, ask simple questions, describe your day in the present tense.
Elementary (A2)3–4Tell a story in the past, make plans for the future, describe people and places.
Intermediate (B1–B2)5–6Explain opinions, handle most everyday and work situations, understand connected speech.
Advanced (C1)7–8Read academic or professional text, argue a position, write a structured report.
Expert (C2)9–10Match a well-educated native speaker's precision, register, and range.

Grammar Basics

Everything else in English is a variation on what's here. Learn this section well and you can already build a correct, if simple, sentence about almost anything.

The eight word classes

Every English word belongs to one of these jobs. Knowing the job tells you where the word can go in a sentence.

ClassJobExamples
NounNames a person, place, thing, or ideateacher, city, freedom
PronounReplaces a nounI, you, it, they
VerbShows an action or staterun, be, seem
AdjectiveDescribes a nountall, quiet, blue
AdverbDescribes a verb, adjective, or another adverbquickly, very, well
PrepositionShows relation (place, time, direction)in, on, before
ConjunctionJoins words or clausesand, but, because
DeterminerIntroduces a nouna, the, this, my

✓Subject–Verb–Object

The default word order in an English statement is Subject, then Verb, then Object (SVO). This order is stricter in English than in many languages — swapping it usually changes the meaning or breaks the sentence.

She (S) reads (V) the newspaper (O).
✗ Reads she the newspaper.

Time and place expressions usually go at the end: She reads the newspaper every morning in the kitchen.

✓Building a longer sentence

A sentence needs at least a subject and a verb. Everything else is optional detail, added in a fairly fixed order:

Subject → Verb → Object → Manner → Place → Time
The team finished the project quickly at the office yesterday.

aA, an, and the

  • a / an — one, unspecified example of something (a before a consonant sound, an before a vowel sound): a book, an hour, a university.
  • the — a specific thing both speaker and listener already know: the book you lent me.
  • No article — general or plural ideas: Dogs are loyal. I like music.

sPlurals

RuleSingularPlural

This/that point to one thing (near/far); these/those point to more than one.

The verb "to be"

SubjectPresentPast
Iamwas
you / we / theyarewere
he / she / itiswas

Used for identity, description, and location: I am a nurse. She is tired. They are at home.

Present simple vs. present continuous

Present simple — habits, facts, routines: add -s for he/she/it.

I work from home. She works from home.

Present continuous — actions happening right now: am/is/are + verb-ing.

I am working right now. She is working right now.

Yes/No questions and negatives

Most tenses need an auxiliary verb (do, does, did, am, is, are) to form a question or a negative.

Statement: You like coffee.
Question: Do you like coffee?
Negative: I do not (don't) like coffee.

Wh- questions

What, where, when, who, why, how go before the auxiliary: Where do you live? Why is she late?

Building Blocks

This is the grammar of everyday fluency — talking about the past and future, comparing things, and connecting ideas beyond one short sentence.

Past simple

Regular verbs add -ed; many common verbs are irregular and must be learned individually.

I walked home. She went home. They ate dinner.
BasePastBasePast
gowentseesaw
havehadmakemade
taketookcomecame
saysaidgetgot

Past continuous

An action in progress at a specific point in the past — often interrupted by another action.

I was cooking dinner when the phone rang.

Three ways to talk about the future

FormUseExample
will + verbDecisions made now, predictions, promisesI think it will rain.
going to + verbPlans already decidedWe are going to visit Rome in July.
present continuousFixed arrangementsI'm meeting her at six.

Present perfect

have/has + past participle — connects the past to now: an experience at an unspecified time, or something that started in the past and continues.

I have visited Japan twice. She has lived here since 2019.

Compare with past simple, which needs a finished, specific time: I visited Japan in 2019 (not "have visited... in 2019").

Past perfect

had + past participle — the earlier of two past events.

By the time we arrived, the film had already started.

Modal verbs

Modals sit before the base verb (no "to," no -s) and add meaning like ability, permission, obligation, or possibility.

ModalMeaningExample
can / couldability, permissionI can swim. Could I leave early?
must / have toobligationYou must wear a seatbelt.
shouldadviceYou should see a doctor.
may / mightpossibilityIt might rain later.
need notlack of obligationYou needn't come if you're busy.

Comparatives and superlatives

Adjective typeComparativeSuperlative
Short (1 syllable)fast → fasterfast → the fastest
Ending in -yhappy → happierhappy → the happiest
Long (2+ syllables)more expensivethe most expensive
Irregulargood → better, bad → worsethe best, the worst
This route is faster, but that one is the most scenic.

Prepositions of time and place

atonin
Timeprecise time — at 6pmdays/dates — on Mondaylonger periods — in June, in 2024
Placea point — at the doora surface — on the tablean enclosed space — in the room

Advanced Grammar

These structures aren't strictly necessary for everyday speech, but they're what separates fluent from precise — and they're essential for academic and professional writing.

Active vs. passive

The passive shifts focus from who did an action to what happened, using be + past participle. It's common in formal, scientific, and journalistic writing where the actor is unknown or unimportant.

Active: The committee approved the budget.
Passive: The budget was approved (by the committee).

The conditional ladder

TypeStructureUseExample
Zeroif + present, presentGeneral truthsIf you heat water, it boils.
Firstif + present, willReal future possibilityIf it rains, we'll stay in.
Secondif + past, wouldUnreal/hypothetical presentIf I had more time, I would travel.
Thirdif + past perfect, would haveUnreal past — regretIf I had studied, I would have passed.
Mixedif + past perfect, wouldPast cause, present resultIf I had taken that job, I would be in Tokyo now.

Direct → reported speech

When you report what someone said, tenses usually shift one step into the past, and pronouns/time words adjust to the new context.

Direct: "I am tired," she said.
Reported: She said (that) she was tired.

Direct: "I will call you tomorrow."
Reported: He said he would call me the next day.

Relative clauses

Add detail to a noun using who, which, that, whose, where. A defining clause is essential to meaning (no commas); a non-defining clause adds extra, removable information (set off with commas).

Defining: The woman who called earlier is my aunt.
Non-defining: My aunt, who lives in Boston, is visiting next week.

Gerund (-ing) or infinitive (to + verb)?

Some verbs are followed by a gerund, some by an infinitive, and some by either — sometimes with a change in meaning.

Followed by -ingFollowed by to + verbEither (meaning changes)
enjoy, avoid, suggest, finishwant, decide, plan, agreestop, remember, try
He stopped smoking (quit the habit).
He stopped to smoke (paused in order to smoke).

Phrasal verbs

A verb plus one or two particles (up, out, off, into...) that together take on a meaning you can't always guess from the parts. Common in spoken English; understanding them is often what separates textbook English from real conversation.

Phrasal verbMeaning
give upstop trying / quit
look intoinvestigate
put offpostpone
run intomeet by chance
figure outunderstand / solve

Register: formal vs. informal

Fluent writing matches its vocabulary and structure to context. Academic and professional English favors precise verbs, nominalization, and hedged claims over casual phrasing.

InformalFormal
get betterimprove
a lot ofsubstantial / considerable
find outdetermine / ascertain
I thinkit appears that / the evidence suggests

Cohesion devices

Connect ideas across sentences with signposting language rather than repeating "and" and "but": however, therefore, moreover, consequently, nevertheless, in contrast, as a result.

The subjunctive & inversion

Formal English keeps a few older structures alive: I suggest that she attend the meeting (subjunctive, not "attends"); Never have I seen such chaos (inversion for emphasis, instead of "I have never seen").

The Word Bank

Ordered from the words that appear constantly in English (level 1) to specialized, formal, and literary vocabulary (level 10). Search by word, or filter by level and part of speech.

1000 words

A self-study plan

Grammar rules and word lists don't turn into fluency by themselves — they need repetition, in context, spread out over time. Here's a stage-by-stage rhythm to follow.

Levels 1–2

Get the sentence working

Drill "to be," present simple, and basic word order daily. Learn 10 new level-1/2 words a day and use each in one spoken sentence. Read very simple text (graded readers, children's books) aloud.

Levels 3–4

Add time and description

Practice past and future forms by narrating your day out loud. Keep a short daily journal, three sentences, mixing tenses. Add comparatives when describing things around you.

Levels 5–6

Move into real conversation

Focus on modals, perfect tenses, and phrasal verbs — this is where textbook English becomes spoken English. Watch shows with English subtitles and note phrasal verbs you hear.

Levels 7–8

Read and write with structure

Study passive voice, conditionals, and reported speech through real articles. Practice rewriting informal sentences in a more formal register using level 7–8 vocabulary.

Levels 9–10

Refine precision

Read academic, legal, or literary text and log unfamiliar words. Practice using one new level 9–10 word correctly in writing each day — precision here comes from active use, not recognition.

Every stage

Habits that carry you through

Speak out loud daily, even alone. Review yesterday's new words before learning today's. Favor short, frequent sessions over long, rare ones.
