Wiktionary is more objective than Wikipedia about what it includes. Our goal is to describe every language, the way it is used or has been used, from a neutral point of view. That means that if something is a word and can be demonstrated to be in use (on which see below), then it can be included.

Wiktionary is a multilingual, web-based project to create a free content dictionary of all words in all languages. It is collaboratively edited via a wiki, and its name is a portmanteau of the words wiki and dictionary.

Wiktionary:Main Page. 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 was brought online on December 12, 2002, following a proposal by Daniel Alston and an idea by Larry Sanger, co-founder of Wikipedia. On March 28, 2004, the first non-English Wiktionaries were initiated in French and Polish. Wiktionaries in numerous other languages have since been started.
