How to build your English vocabulary

Many English learners run into the same problem: they learn words and forget them a week later; they recognise a word in a text but cannot recall it when speaking. The cause is usually not ability but method. In this article we look at how to grow your vocabulary systematically: which words to start with, the difference between passive and active vocabulary, learning words together with their collocations and word families, keeping a proper vocabulary notebook, reviewing with Leitner boxes, using an English-English dictionary, picking up words through reading, dealing with false friends and phrasal verbs, and putting words into active use. At the end you will find an 8-week plan for a hypothetical student, common mistakes, an exercise and a checklist. If you need an overall plan for learning the language, read our article on learning English on your own first — here we focus in depth on vocabulary alone.

Which words to start with

English has a huge number of words, but they are not all equally useful. For every word, ask yourself two questions: “Do I come across it often?” and “Will I actually use it?”

The most frequent words

In everyday speech and writing, a relatively small group of words comes up again and again: make, take, get, go, have, time, people, way, work, think, need. Learning these first pays off fastest, because they appear in every text and every conversation. Ready-made lists exist too: for example, the Oxford Learner’s Dictionaries website publishes core word lists called “Oxford 3000” and “Oxford 5000”, and the Cambridge dictionary shows a level from A1 to C2 next to many words. If your level is A1–A2, start with words at that level and leave harder ones for later.

Words from your own field

The second group is words connected with your life and your job. An accountant needs invoice, balance, tax return, receipt; a nurse needs prescription, blood pressure, symptom; a programmer needs deploy, repository, bug. These words may sit far down general lists, but you see them every day. Start a separate list for your field and add 5–10 words to it each week.

A simple rule: if you have come across a word at least two or three times in the past month and it relates to your subject, learn it.

Passive and active vocabulary

Passive vocabulary is the words you recognise when reading or listening. Active vocabulary is the words you can use yourself when speaking and writing. Your passive vocabulary will always be larger than your active one, and that is perfectly normal. The real problem is different: many learners consider a word learnt as soon as they recognise it, and never move it into active use.

Every word goes through several stages:

1. Recognition. When you see the word, you roughly know what it means.
2. Understanding. You know the meaning precisely and understand the word correctly in a sentence.
3. Recall. Looking at the translation, you can produce the English word yourself.
4. Use. You use the word in your own sentences, in the right collocation, without stopping to think.

So do not test yourself only in the “English → your language” direction. The reverse direction, “your language → English”, is noticeably harder, but it is exactly what makes a word active. You do not need to make every word active: words you only need for reading can stay passive, but vocabulary for work and everyday communication is worth moving into active use.

Learning words in context

A list of single words with translations is the weakest method. A word lives in a sentence, next to other words, and that is how it is remembered.

Collocations

A collocation is a group of words that naturally go together. In Uzbek we say “qaror qilmoq”, literally “do a decision”, but in English it is make a decision, not do a decision. Similar pairs:

• make a decision, make a mistake, make a phone call, but do homework, do the shopping, do exercise;
• take a photo, take a break, take a bus;
• pay attention, pay a visit;
• heavy rain, strong tea, fast food, but for a short shower we say a quick shower, not a fast shower.

So write make a decision in your notebook, not just decision. When you meet a new word, look at its neighbours too: which verb and which preposition does it come with? For example, interested in, depend on, good at.

Word families

Several words can be formed from one root. Learn them together and you get four words instead of one:

• decide — decision — decisive — indecisive;
• employ — employer — employee — employment — unemployed;
• success — succeed — successful — successfully.

Pay attention to suffixes and prefixes: -tion and -ment often form nouns, -ful, -ive and -able form adjectives, -ly forms adverbs, and un-, in- and dis- add a negative meaning. This knowledge also helps you guess the meaning of unfamiliar words.

Vocabulary notebook and review

How to set out a card

A well-organised entry is half the battle. In your notebook or on each flashcard, give every word five parts:

1. The word or phrase, ideally as a whole collocation: make a decision.
2. Pronunciation, either a transcription or a spelling that makes sense to you. Listen to the audio in an online dictionary and repeat it aloud.
3. An example sentence from the dictionary, which shows how the word is used.
4. A translation, short: one or two words.
5. Your own sentence, about your own life. This is the part that makes the word “yours”.

A sample card:

make a decision — qaror qabul qilmoq
Example: We need to make a decision by Friday.
My sentence: I made a decision to study English every morning.

It helps to divide the notebook by topic: “Work”, “Home”, “Travel”, “Health”. A digital version works too: a notes app on your phone or a spreadsheet with columns for the word, pronunciation, example, translation, your sentence and the date. The key is to keep everything in one place so that words do not end up scattered across dozens of scraps of paper and chats.

Spaced repetition and Leitner boxes

A new word is forgotten quickly, but each well-timed review keeps it in memory for longer. This is the idea behind spaced repetition; we explain why it works in our article on remembering what you learn. Here we focus on the practice.

Apps. Flashcard apps such as Anki work out the review schedule for you: you mark how easily you remembered a word, and the app sets the day of the next review. Make your own cards — words you have met yourself stick better than someone else’s words from ready-made decks.

By hand: Leitner boxes. A simple method that works without any app. Prepare several boxes or envelopes, say five. The table below is one common version; you can adjust the intervals to suit you:

Step by step:

1. All new cards go into Box 1.
2. On review day, take out the cards, look at the translation side and say the English phrase and your own sentence aloud.
3. Remembered it correctly? The card moves up to the next box.
4. Could not remember it or got it wrong? The card goes back to Box 1, whichever box it was in.
5. Once you have confidently remembered a word from Box 5 several times, move it to a “learnt” pile and glance through that pile from time to time.

Add 5–10 new cards a day. Add more, and within a week the review load will overwhelm you and the habit will fall apart.

English-English dictionaries and reading

English-English dictionaries

A bilingual dictionary is useful at the start, but once you reach A2–B1, begin moving to English-English learner’s dictionaries. Dictionaries such as the Cambridge Dictionary and Oxford Learner’s Dictionaries have free online versions. They are written specifically for learners, with definitions in simple language.

What to look at when you open a word in such a dictionary:

• pronunciation: British and American audio;
• part of speech: noun, verb, adjective;
• example sentences, which show the contexts the word appears in;
• collocations: many dictionaries list the words it is typically used with;
• level and usage labels: whether the word is formal or informal, British or American.

Reading the definition and then trying to explain the word in English in your own words is an exercise in itself.

Building vocabulary through reading

Flashcards consolidate words, but to find new ones and meet them again in different contexts, you need to read. The best place to start is graded readers: books adapted to different levels. Their vocabulary and grammar are simplified to match the level, so you can read without reaching for the dictionary in every sentence. Look for them in libraries, learning centres and on publishers’ official websites.

The next step is articles on a topic you love: sport, cooking, technology or your profession. An interesting topic keeps you reading to the end, and the same words keep coming back.

Rules of thumb: if you understand nearly all of the text, the level is right; if you are checking the dictionary every other sentence, the material is too hard for now. Do not write down every unfamiliar word: first try to guess the meaning from context, and take only the 3–5 most useful phrases from each page. Our article on effective reading covers reading technique in detail.

False friends and phrasal verbs

False friends

False friends are English words that look like Uzbek or Russian words but mean something different. They are especially tricky because the word seems familiar, so you never check the dictionary:

• magazine means a periodical, not a shop. A shop is a shop or a store.
• artist usually means a painter or a creative person in general. A stage actor is an actor, a singer is a singer, and a stage performer in general is a performer.
• family means the people you are related to. The Uzbek and Russian “familiya” is a surname or family name, sometimes a last name.
• accurate means precise and free of errors. For “akkurat” in the sense of neat and orderly, use neat or tidy.
• fabric means cloth. A “fabrika” is a factory.
• cabinet means a cupboard or a group of government ministers. A personal workroom is an office.
• decade means ten years, not ten days.
• actual means real. For “aktual” in the sense of topical, use relevant or topical.

Give these words their own page in your notebook and write a correct example for each: I bought a magazine at the shop.

Learn phrasal verbs in groups

A phrasal verb is a verb plus a small word such as up, on, off or out: give up (stop trying, quit), look after (take care of). Learning them in alphabetical order is hard going. Group them instead:

• By verb: look for (search for), look after (take care of), look up (check in a dictionary), look forward to (be excited about something in the future).
• By topic: clothes — put on, take off, try on; devices — turn on, turn off, plug in; work — fill in a form, set up a meeting, call back.
• By meaning: up often signals completion — eat up, clean up, use up.

Write your own sentence for every phrasal verb: I look after my younger brother on Saturdays.

Putting words into active use

A word only enters your active vocabulary through use. A few minutes a day is enough:

• Make sentences. Write 2–3 sentences of your own with each new phrase, then say them aloud.
• Keep a diary. In the evening, describe your day in 5–6 sentences and use at least two words you learnt that day.
• Use them when speaking. Before a conversation or a voice message, set yourself a “task” of 2–3 new phrases and make sure you use them. Our article on speaking English has more on speaking practice.
• Retell. In one minute, retell an article you have read or audio you have listened to, using the new words. For listening tips, see our article on listening in English.

If you are preparing for an international exam, bear in mind that the writing and speaking sections assess precisely your active vocabulary; we cover this in our article on international language exams.

Example: Malika’s 8-week plan

Malika is a hypothetical student at a college in Samarkand, at roughly A2 level. Her goal is to speak more freely about everyday and study topics within two months. She sets aside 25–30 minutes a day. The plan and figures below are an illustrative example; adapt them to your own situation.

One day a week Malika adds no new words and only reviews her boxes. At the end of week 8 she checks not how many words she knows but how well she can use them, by comparing her recordings from week 1 and week 8.

Mistakes, practice and checklist

Common mistakes

• Memorising long word lists with translations, without examples or collocations.
• Adding too many new words a day, then giving up on review after a week.
• Testing yourself only in the “English → your language” direction.
• Not checking pronunciation, so the word “sets” with the wrong sound.
• Trusting false friends and not checking the dictionary.
• Choosing texts far above your level and looking up a word in every sentence.
• Never using a new word in your own speech.

Practice exercise

A one-week exercise:

1. Open a vocabulary section in your notebook or app and set up a five-part card template.
2. Choose 10 words from your own field and write them down with their collocations.
3. Look up the word family of one word in a dictionary: for example, decide or employ.
4. Open 3 words in an English-English dictionary: listen to the pronunciation and copy one example sentence for each.
5. Prepare five Leitner boxes or envelopes and put your cards into Box 1.
6. Read one short article on a favourite topic and take 3–5 phrases from it.
7. Add 3 false friends and one group of phrasal verbs to your list.
8. At the end of the week, record a one-minute voice message using at least five new words.

Checklist

• Every word is recorded with its collocation and an example sentence.
• You have listened to the pronunciation audio.
• Every word has a sentence of your own.
• Review happens daily, and cards are in the right boxes.
• You test yourself in both directions: “English → your language” and “your language → English”.
• At least once a week, new words are used in speaking or writing.

Vocabulary does not grow in a day but through small daily steps. It is part of lifelong learning: every new English phrase opens the way to new books, courses and opportunities.
