For the word 'thesaurus', see thesaurus

This is the main project page of Wiktionary Thesaurus, a Wiktionary subproject and a wiki namespace aiming at creating a thesaurus, a dictionary of synonyms, antonyms, and further semantically related terms such as hyponyms, hypernyms, meronyms, and holonyms. The project was formerly called Wikisaurus.

The purpose of Wiktionary Thesaurus is to serve the role of an electronic thesaurus—a dictionary of synonyms, near-synonyms and antonyms, and near-antonyms, but also of other semantically related terms such as hyponyms, hypernyms, meronyms, holonyms.

The purpose of such a thesaurus in general is mainly to help anyone who writes for living or fun—writers, managers, contributors to wikis, bloggers, and writers of love letters—to find words they don't recall or even know when they recall words that are semantically related to the sought word. In general, anyone to whom the choice of words matters can benefit from a thesaurus, especially one linked to a dictionary providing the definitions.

Added value of Wiktionary Thesaurus is its Wiktionary integration—it links to and is linked from Wiktionary.


Candidate model thesauri include Roget's thesaurus, and, say, The Penguin Thesaurus. The two follow different design principles.


English Wiktionary Thesaurus is multilingual; it contains entries for other languages than English[1]. Such entries include Thesaurus:příbuzný and Thesaurus:juoppo. An alternative naming of the entries is "Thesaurus:cs:příbuzný" and "Thesaurus:fi:juoppo", in part modeled on the naming of topic categories. Yet another alternative is "Thesaurus:cs:relative" and "Thesaurus:fi:drunkard" using English headwords prefixed by the language.


Languages that have at least one Thesaurus entry include Arabic: Thesaurus:صار, Azerbaijani: Thesaurus:yaxşı, Chinese: Thesaurus:舒適, Czech: Thesaurus:příbuzný, Danish: Category:Danish thesaurus entries, Finnish: Thesaurus:juoppo, French: Thesaurus:chat, German: Thesaurus:sehr, Hindi: Thesaurus:मनुष्य, Japanese: Thesaurus:レストラン, Korean: Thesaurus:한글, Polish: Thesaurus:gruchot, Portuguese: Thesaurus:duradouro, and Telugu: Thesaurus:కుక్క.


Formatting is specified and discussed at:

Example entries:


The inclusion criteria for Thesaurus entries are the same as those for the mainspace: Wiktionary:Criteria for inclusion.

Additionally, all items in lists of synonyms, antonyms, hyponyms, etc. on Thesaurus pages are required to be attested, using the same attestation criteria as the mainspace.[2]


Lists of templates:


Template Example Note
  • {{ws|beer|An alcoholic fermented malt drink.}}
  • {{ws|beer|*}}
  • {{ws|beer}}
The second entry is a lazy one. The third one shows no tooltip, but also does not make it clear that one is missing.
To be put around a list of {{ws}} entries. Currently formats the list as a 3-column one.


Entered at the very top of the entry. When without parameter, determines the headword automatically.
{{R:Roget 1911|beauty}} beauty” in Roget's Thesaurus, T. Y. Crowell Co., 1911.
{{ws sense|glad; in a good mood}} Sense: glad; in a good mood Used after the third level heading for the part of speech.


Linking from mainspace to Thesaurus entries:

  • Links to thesaurus entries can be added to the "Synonyms" section (or "Hyponyms", "Antonyms", etc. where appropriate) using the template {{seeSynonyms}} (which displays something like: See Thesaurus:error), or using conventional wikitext syntax (''See also'' [[Thesaurus:error]]).
  • The {{synonyms}} template, used to render per-sense synonyms directly beneath definitions, accepts Thesaurus: links, which should be placed after any specific synonyms (e.g. {{synonyms|en|goof|blunder|Thesaurus:error}})
  • Especially for Thesaurus entries featuring mostly synonyms, it is good to add a link to the Thesaurus entry from all the mainspace entries for the synonyms, so that the user knows that there is a Thesaurus entry when visiting the mainspace.


The current title of the project is "Thesaurus" and "Wiktionary Thesaurus". Before mid-2017, it was "Wikisaurus". Alternatives considered include "Wikithesaurus". In the past, WikiSaurus spelling with capital 'S' must have existed at some point.
