What it does
Longman's online dictionary combines English word lookup, topic groups and vocabulary exercises.
Search a word encountered in reading, then explore its topic group to find related vocabulary. The exercise area offers practice with synonyms, collocations and idioms. Keep the reference lookup as the starting task when you need one precise meaning rather than a broader study session.
