Self-Study Reference — Edition 01
English.
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
| Stage | Word levels | You can |
|---|---|---|
| Beginner (A1) | 1–2 | Introduce yourself, ask simple questions, describe your day in the present tense. |
| Elementary (A2) | 3–4 | Tell a story in the past, make plans for the future, describe people and places. |
| Intermediate (B1–B2) | 5–6 | Explain opinions, handle most everyday and work situations, understand connected speech. |
| Advanced (C1) | 7–8 | Read academic or professional text, argue a position, write a structured report. |
| Expert (C2) | 9–10 | Match 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.
| Class | Job | Examples |
|---|---|---|
| Noun | Names a person, place, thing, or idea | teacher, city, freedom |
| Pronoun | Replaces a noun | I, you, it, they |
| Verb | Shows an action or state | run, be, seem |
| Adjective | Describes a noun | tall, quiet, blue |
| Adverb | Describes a verb, adjective, or another adverb | quickly, very, well |
| Preposition | Shows relation (place, time, direction) | in, on, before |
| Conjunction | Joins words or clauses | and, but, because |
| Determiner | Introduces a noun | a, 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.
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:
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
| Rule | Singular | Plural |
|---|---|---|
| Add -s | book | books |
| -s, -x, -ch, -sh → -es | box | boxes |
| Consonant + y → -ies | city | cities |
| -f/-fe → -ves | leaf | leaves |
| Irregular | child, man, mouse | children, men, mice |
Personal & possessive pronouns
| Subject | Object | Possessive adj. | Possessive pronoun |
|---|---|---|---|
| I | me | my | mine |
| you | you | your | yours |
| he | him | his | his |
| she | her | her | hers |
| it | it | its | — |
| we | us | our | ours |
| they | them | their | theirs |
This/that point to one thing (near/far); these/those point to more than one.
The verb "to be"
| Subject | Present | Past |
|---|---|---|
| I | am | was |
| you / we / they | are | were |
| he / she / it | is | was |
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.
Present continuous — actions happening right now: am/is/are + verb-ing.
Yes/No questions and negatives
Most tenses need an auxiliary verb (do, does, did, am, is, are) to form a question or a negative.
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.
| Base | Past | Base | Past |
|---|---|---|---|
| go | went | see | saw |
| have | had | make | made |
| take | took | come | came |
| say | said | get | got |
Past continuous
An action in progress at a specific point in the past — often interrupted by another action.
Three ways to talk about the future
| Form | Use | Example |
|---|---|---|
| will + verb | Decisions made now, predictions, promises | I think it will rain. |
| going to + verb | Plans already decided | We are going to visit Rome in July. |
| present continuous | Fixed arrangements | I'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.
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.
Modal verbs
Modals sit before the base verb (no "to," no -s) and add meaning like ability, permission, obligation, or possibility.
| Modal | Meaning | Example |
|---|---|---|
| can / could | ability, permission | I can swim. Could I leave early? |
| must / have to | obligation | You must wear a seatbelt. |
| should | advice | You should see a doctor. |
| may / might | possibility | It might rain later. |
| need not | lack of obligation | You needn't come if you're busy. |
Comparatives and superlatives
| Adjective type | Comparative | Superlative |
|---|---|---|
| Short (1 syllable) | fast → faster | fast → the fastest |
| Ending in -y | happy → happier | happy → the happiest |
| Long (2+ syllables) | more expensive | the most expensive |
| Irregular | good → better, bad → worse | the best, the worst |
Prepositions of time and place
| at | on | in | |
|---|---|---|---|
| Time | precise time — at 6pm | days/dates — on Monday | longer periods — in June, in 2024 |
| Place | a point — at the door | a surface — on the table | an 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.
Passive: The budget was approved (by the committee).
The conditional ladder
| Type | Structure | Use | Example |
|---|---|---|---|
| Zero | if + present, present | General truths | If you heat water, it boils. |
| First | if + present, will | Real future possibility | If it rains, we'll stay in. |
| Second | if + past, would | Unreal/hypothetical present | If I had more time, I would travel. |
| Third | if + past perfect, would have | Unreal past — regret | If I had studied, I would have passed. |
| Mixed | if + past perfect, would | Past cause, present result | If 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.
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).
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 -ing | Followed by to + verb | Either (meaning changes) |
|---|---|---|
| enjoy, avoid, suggest, finish | want, decide, plan, agree | stop, remember, try |
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 verb | Meaning |
|---|---|
| give up | stop trying / quit |
| look into | investigate |
| put off | postpone |
| run into | meet by chance |
| figure out | understand / 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.
| Informal | Formal |
|---|---|
| get better | improve |
| a lot of | substantial / considerable |
| find out | determine / ascertain |
| I think | it 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.
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.
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.
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.
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.
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.
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.
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.
