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.
Try these words in a real IELTS Writing Task 2 question:
For natural word pairs on this topic, see our IELTS collocations by topic, and to connect your ideas, our IELTS linking words.
Lexical Resource also counts for a quarter of your Speaking band.

In Part 1, everyday words usually sound more natural.
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.

The knock-on effect is that young people never learn to cook, which in turn could affect their health later on.
The words in bold are from this page. Notice that each one is part of a natural spoken sentence, followed by a reason or an example.

Many Part 3 questions ask why something happens or what its effects are. Phrases such as stem from and the knock-on effect help you explain your reasoning clearly.
Learn each word with an example sentence and the words it is usually used with, review the list a few times a week, and use three or four of the words in every practice essay and Speaking Part 3 answer until they feel natural.
