Collins Dictionaries contains a dictionary, thesaurus, word and language studies and word games.
Dictionary.com is a multi-source dictionary search service produced by Lexico Publishing Group, LLC, a leading provider of online language reference products and services.
Think of this website as a search engine for words and phrases. If you have a word for which you’d like a definition or translation, OneLook will quickly shuttle you to the web-based dictionaries that define or translate that word. If you don’t know how to spell the word, OneLook will help you do that too.
Pseudodictionary is the place where words you’ve made up can become part of an actual online dictionary! Slang, “webspeak,” colloquialisms…if you know a word that should be in the dictionary but isn’t, submit it and Pseudodictionary will post it (with credit given to you of course).
Free Reference containing English, medical, legal, financial and computer dictionaries. Free Reference also includes a thesaurus, acronyms, idioms, encyclopedia, literature reference library and a search engine.
