Why practice Prefixes exercises?

These prefix exercises build your word-building skills step by step, covering levels A2 to B2. Start with the most common negative prefixes un- and dis- (happy → unhappy, agree → disagree), then master the tricky in- family with its phonological variants im-, il-, and ir- (possible → impossible, legal → illegal). Learn negative adjective prefixes to form opposites, practise meaning-changing prefixes like re-, pre-, over-, and under- to expand your vocabulary, and finish with mixed exam-style practice combining all prefix types for FCE and CAE preparation.
