How to teach IELTS vocabulary (Lexical Resource) without word lists

By the IELTS Laboratory team. Published 22 October 2026. Updated 22 October 2026.

Short answer: Teach IELTS vocabulary by upgrading the words students already over-use in their own essays and recordings, and by teaching words in the combinations they naturally appear in (collocations). Precision and natural use matter more than rare words, so a short list of each student’s own repeated words is a better starting point than a long topic word list.

Many students arrive with lists of “band 9 words” and use them in ways that sound forced. The fix is usually fewer new words, used more accurately.

What is Lexical Resource in IELTS?

Lexical Resource is the IELTS criterion for vocabulary. It is one of four criteria in both Writing and Speaking, and it looks at the range, precision and naturalness of the words a candidate uses.

In practice, that means three things:

• Range: enough variety that the same words aren’t repeated.

• Precision: the word means exactly what the candidate intends.

• Natural use: the word is used in the combinations and style a fluent speaker would expect.

Students tend to focus only on range. Precision and natural use are where most marks are actually lost.

Why don’t IELTS vocabulary lists work on their own?

Because a word on a list gives the meaning but not how to use it, so students produce sentences that are technically impressive and actually wrong.

Typical results (invented examples):

• The government should ameliorate the problem of traffic. (formal word, unnatural here)

• Pollution is a detrimental issue. (wrong collocation: things have a detrimental effect)

• Nowadays, many people utilise the internet. (use is simpler and more natural)

Lists can still help, but only as raw material for practice in context.

What is a collocation, and why does it matter?

A collocation is a pair or group of words that naturally go together, such as make a decision, heavy traffic or raise awareness.

Collocations matter because a correct word in the wrong combination still sounds wrong. Teaching words as collocations from the start avoids errors like do a decision or strong traffic.

What does an IELTS vocabulary lesson from students’ own work look like?

It runs collect, sort, upgrade and reuse, and takes about 50 minutes.

1. What words should you collect? (before class)

The general words students lean on most, such as good, bad, thing, very, a lot of, people and big.

Scan three or four recent essays or transcripts per student. You’ll usually find the same handful in every class.

2. How do you show the repeats? (10 minutes)

Write each over-used word with two or three real sentences it appeared in, with details changed so nobody is identified.

Seeing good five times in a row is often enough for students to see the problem themselves.

3. How do students upgrade in context? (15 minutes)

Pairs suggest replacements that fit each specific sentence, not a general synonym.

A good job might become a well-paid job or a rewarding job, depending on what the writer meant. That choice is the precision skill IELTS rewards.

4. How do you check collocations? (10 minutes)

Ask students to test each option with a learner’s dictionary or a collocation dictionary, and reject combinations that don’t appear.

5. How do students reuse the upgrades? (10 minutes)

Each student rewrites one paragraph of their own essay, or re-records one speaking answer, using at least two upgrades.

Reuse is what moves a word from “recognised” to “usable”.

6. What goes on the personal list? (5 minutes)

Three upgrades each student will try in their next essay or speaking practice.

What are good IELTS vocabulary exercises?

Exercises that ask students to choose and produce words in context work better than matching definitions.

• Paraphrase the question: rewrite a Task 2 question in different words without changing its meaning.

• Collocation sort: sort verbs such as make, do, take and have with nouns that collocate with them.

• Word family chains: economy, economic, economical, economically, then use each correctly.

• Precision ladders: rank small, slight, minor, marginal by meaning and use each in a sentence about data.

• Speaking upgrade: after a recorded Part 2 talk, students pick two words to improve and record again. See how to teach IELTS Speaking Part 2.

Where do vocabulary mistakes fit in the bigger picture?

Vocabulary is one of four criteria, so treat it alongside the others rather than in isolation.

Word form errors (economic for economy) and wrong collocations often hold writing back more than a lack of rare words. Rank them with the other mistakes a student makes, as described in our guide to lesson plans built from learners’ mistakes.

How can IELTS Laboratory help with vocabulary?

IELTS Laboratory (ielts-laboratory.co) is an independent online platform for IELTS teachers and learners that turns learners’ own Writing and Speaking mistakes into flashcards, lesson packs and practice. It is not affiliated with IELTS, the British Council, IDP or Cambridge.

It saves time on the collecting stage:

• Flashcards from each essay, including vocabulary and collocation fixes, go into each learner’s own deck, and missed cards come back sooner.

• Speaking reports keep each recording with a click-to-play transcript, and you mark the errors yourself.

• The Mistakes tab ranks a class’s mistakes by damage for any period, from the cards on each essay, so the most-repeated vocabulary problems are easy to spot.

• A class puzzle turns the group’s mistakes into an anonymised text to fix together, and each student gets a personal puzzle.

Nothing in the product is an official IELTS score.

FAQ

How do you teach vocabulary for IELTS?

Start from the words students over-use in their own work, upgrade them in context, teach collocations, and have students reuse the new words straight away.

Should IELTS students learn “advanced” vocabulary?

Only if they can use it accurately. Precise, natural use of common words is worth more than rare words used wrongly.

What is Lexical Resource in IELTS Speaking?

It is the vocabulary criterion: range, precision and natural use of words, including the ability to paraphrase when a word is missing.

What are good IELTS vocabulary resources?

A learner’s dictionary with example sentences, a collocation dictionary, and your students’ own essays and recordings, which show exactly which words they need.
