How to actually use crime & law vocabulary in the exam

A word list is where vocabulary study starts and where most of it unfortunately stops. Lexical Resource is a quarter of your Writing and Speaking band, and it is not scored on how many unusual words you produce — it is scored on precision, collocation and word formation. A common word used exactly beats a rare one used approximately, every time.

Where crime & law actually comes up. Topic vocabulary earns most in Speaking Part 3, where questions turn abstract and general, and in Writing Task 2, where a precise word can carry an argument a vague one cannot. It matters least in Listening and Reading, where you need to recognise paraphrase rather than produce it — which is exactly why passive list-reading feels like it is working while your Speaking and Writing bands stay where they were.

A realistic way to use this page. Take five words, not fifty. Write one sentence with each, on a question you might genuinely be asked. Say them out loud, because a word you have never pronounced will not arrive under pressure. Come back in a few days and produce them from the definitions alone. Five words you can use are worth more in the exam than fifty you can recognise, and that ratio is the whole reason most vocabulary study does not move a band.
