Words With is a search engine for words corresponding to constraints (presence or absence of certain letters, beginning or end, number of letters or letters at precise positions).
It can be useful for all word games: crossword puzzle creation or solution, crossword puzzles, hangman, The Longest Word
(Numbers and letters), Scrabble, Boggle, Words With Friends etc. as well as for literary creation: search for rhymes and alterations for poetry, and for words satisfying the constraints of thePotential Literature Workshop (OuLiPo) such as lipograms, pangrams, anagrams, monovocalism and monoconsonantism etc.
Note: the Wiktionary contains many more words (in particular proper names) than other French dictionaries such as the dictionary Scrabble official (ODS) published by Larousse: approximately 400,000 words and inflected forms (nouns and adjectives in the masculine and feminine and in the singular and plural, conjugated verbs) in the ODS, and 1.3 million on Mots Avec.
