Using These Words in IELTS Writing
Lexical Resource is a quarter of your Writing band. Examiners look for a range of topic words used accurately and in natural combinations, not for the longest words you know.
- Use a few well, not many badly. Three or four precise words in an essay are worth more than ten forced ones.
- Learn the word with its partners. Note the collocations in each example sentence, such as the verb that goes with a noun.
- Paraphrase the question. Topic words help you restate the question in your introduction without copying it.

Using These Words in IELTS Speaking Part 3
Lexical Resource also counts for a quarter of your Speaking band. Part 3 is where these words fit best: the examiner asks abstract questions about society, causes, and the future, and a precise topic word shows the range that band 7 and above require. In Part 1, everyday words usually sound more natural.
- Use the word in your own sentence. Memorised phrases are easy for examiners to spot.
- Keep the tone conversational. Mix academic words with natural spoken phrases such as “I’d say” and “on top of that”.
- Support every word with an example. A topic word followed by a real example is what develops a Part 3 answer.
Sample Part 3 answer
I think it largely stems from how busy people are. Long working hours result in people getting home too tired to cook, and delivery apps have made ordering in very easy. Another contributing factor is price, because in many cities eating out is no longer much more expensive. The knock-on effect is that young people never learn to cook, which in turn could affect their health later on.
