Crime & Justice Vocabulary for IELTS
Crime is one of the most discussion-rich Writing Task 2 topics because almost every prompt invites both descriptive (causes, types) and policy (responses, prevention) language. Speaking Part 3 commonly raises crime in the context of cities, technology, or young people. The vocabulary below covers offenders, the justice process, and modern policy debates.
IELTS prompts where this vocabulary fits
- Speaking Part 3: What can governments do to reduce crime?
- Writing Task 2: Some people believe long prison sentences are the best way to reduce crime. Others say rehabilitation works better. Discuss.
- Speaking Part 3: Has technology made crime easier or harder to commit?

Band-8 sample answer
Sample band-8 Writing Task 2 paragraph from an essay on prison versus rehabilitation.
While long sentences can act as a deterrent for the most serious offences, evidence from many countries suggests that rehabilitation reduces recidivism more reliably than imprisonment alone. Education and employment programmes within prison, combined with structured parole, give offenders a realistic path back into law-abiding life. Restorative justice schemes that connect offenders with the victim and the wider community have produced lower reoffending rates in pilot programmes than equivalent prison sentences did, particularly for non-violent and first-time offenders.
Words used: deterrent, rehabilitation, recidivism, parole, offender, law-abiding, restorative justice, victim, reoffending
Using these in IELTS Speaking
IELTS Speaking rewards natural production over recall. Aim to slip a higher-register word like offender or vandalism into your answer at the moment the question invites it, rather than forcing a memorised phrase into the opening sentence. Examiners notice when vocabulary feels rehearsed.
If you are not sure of a collocation, use a slightly safer word you control. A single confident use of court in Part 3 — where the question explicitly invites discussion — gives examiners more evidence of range than a stilted opening sentence with three advanced terms.
Using these in IELTS Writing Task 2
Writing Task 2 rewards precise topic vocabulary in body paragraphs more than in the introduction. The introduction restates the prompt and signals your position; the body paragraphs are where examiners look for evidence of lexical range. Anchor each body paragraph on one main idea and weave in two or three words from this page that genuinely advance the argument.
Avoid the temptation to use every word on this page in a single essay. Two or three accurate uses of less common vocabulary is band-7 territory; five forced uses without natural collocation is a band-6 signal. Pair higher-register vocabulary with simple, grammatically clean sentences rather than the other way around.
Common traps to avoid
The most common crime & justice trap at band 6.5 is collocation mismatch — using a word in a combination native speakers would not produce. The collocations column on the table above is the most important field for avoiding this; learn offender not as a single word but as part of the collocations listed beside it.
The second trap is register mismatch: using an informal word in a Writing Task 2 essay, or an overly formal word in a personal Speaking answer. The example sentences on this page are calibrated to the register IELTS expects for each section listed in the header.
