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 it is available in 172 languages and in Simple English. Like its sister project Wikipedia, Wiktionary is run by the Wikimedia Foundation and its wiki software, MediaWiki, allows almost anyone with access to the website to create and edit entries. The English Wiktionary includes a Wikisaurus of synonyms of various words, Wiktionary data are frequently used in various natural language processing tasks. Wiktionary was brought online on December 12,2002, following a proposal by Daniel Alston, on March 28,2004, the first non-English Wiktionaries were initiated in French and Polish. Wiktionaries in numerous other languages have since been started, Wiktionary was hosted on a temporary domain name until May 1,2004, when it switched to the current domain name. As of November 2016, Wiktionary features over 25.9 million entries across its editions, forty-one Wiktionary language editions now contain over 100,000 entries each. Seven of the 18 bots registered at the English Wiktionary created 163,000 of the entries there, of the 648,970 definitions the English Wiktionary provides for 501,171 English words,217,850 are form of definitions of this kind. This means its coverage of English is slightly smaller than that of major monolingual print dictionaries, the Oxford English Dictionary, for instance, has 615,000 headwords, while Merriam-Websters Third New International Dictionary of the English Language, Unabridged has 475,000 entries. Detailed statistics exist to show how many entries of various kinds exist, the English Wiktionary does not rely on bots to the extent that some other editions do. The French and Vietnamese Wiktionaries, for example, imported large sections of the Free Vietnamese Dictionary Project and these imported entries make up virtually all of the Vietnamese editions contents. Almost all non-Malagasy-language entries of the Malagasy Wiktionary were copied by bot from other Wiktionaries, like the English edition, the French Wiktionary has imported the approximately 20,000 entries from the Unihan database of Chinese, Japanese, and Korean characters. The Russian edition grew by nearly 80,000 entries as LXbot added boilerplate entries for words in English, in 2017 English part of en. wikitionary had over 500,000 gloss definitions and over 900,000 definitions. Wiktionary has historically lacked a uniform logo across its numerous language editions, some editions use logos that depict a dictionary entry about the term Wiktionary, based on the previous English Wiktionary logo, which was designed by Brion Vibber, a MediaWiki developer. Because a purely textual logo must vary considerably from language to language, some communities adopted the winning entry by Smurrayinchester, a 3×3 grid of wooden tiles, each bearing a character from a different writing system. However, the poll did not see as much participation from the Wiktionary community as some community members had hoped, in April 2009, the issue was resurrected with a new contest. This time, a depiction by AAEngelman of an open hardbound dictionary won a vote against the 2006 logo. In the following years, some wikis replaced their logos with one of the two newer logos
