Find the word, meaning or subject you need

Use the main search for definitions, then move into synonyms, origins, subject dictionaries and connected vocabulary.

Search the dictionary

Begin typing any word or phrase. Autocomplete suggests matching entries and shows a short meaning before you open the page.

Search a word to compare alternatives by context, formality, strength and how safely they can replace the original.

Open a subject dictionary for specialist vocabulary in medicine, law, mathematics, computing, economics and other disciplines.

Clusters group words by meaning, tone, use, origin or subject so you can learn vocabulary as a connected set.

Choose a published word cluster and generate a crossword using the definitions as clues.

When reporting an issue, include the page URL, the word involved and a short explanation of what appears incorrect.
