Welcome

to the English-language Wiktionary, a collaborative project to produce a free-content multilingual dictionary. It aims to describe all words of all languages using definitions and descriptions in English.

Wiktionary has grown beyond a standard dictionary and now includes a

thesaurus

, a rhyme guide, phrase books, language statistics and extensive appendices. We aim to include not only the definition of a word, but also enough information to really understand it. Thus

etymologies

, pronunciations, sample quotations, synonyms, antonyms and translations are included.

Wiktionary is a

wiki
