Merriam-Webster OnLine Dictionary - Thesaurus
This is an online up-to-date dictionary and thesaurus where you can browse entries that have already been submitted by other members of the community, but also submit and share entries that aren't already in the dictionary.
This classical thesaurus does not only provide you with the features of a classical thesaurus, i. e. main entry, definition, synonyms and notes, but also with multilingual online translators and dictionaries. The fun & game part also offers classical crosswords, word games, podcasts and multilingual online translators.
This web page concentrates on synonyms. Being a project at Vancouver Webpages, the list is extensible and you can add new words, or add synonyms for an existing word.
Apart from Webster's online searchable dictionary, the web page has thousands of e-books, poems, articles, short stories and plays all of which are absolutely free. Additionally, you will find biographies, references, study guides and teacher resources.
World Wide Words
World Wide Words is devoted to the English language - its history, quirks, curiosities and evolution. Being organised into sections, the web page provides almost everything. Additionally, you will find a large number of essays on rather unusual topics as for example The odd history of omnibus or The vocabulary of British lotteries. There is also a great list of weblinks which refer you to web pages on the English language, the world of words, vocabulary, and linguistics (e. g. American dialects, estuary English, slang, glossaries and dictionary centres).
The free dictionary search gives you definitions, thesaurus entries, spelling, pronunciation, and etymology results. Additionally, it provides resources for a number of languages. You can either browse the dictionary alphabetically or by related terms.
