Thesaurus

    

The word thesaurus is New Latin for treasure; coined in the early 1820's. Besides its meaning as a treasury or storehouse, it more commonly means a listing of words with similar or related meanings. For example, a book of jargon for a specialized field; or more generally a list of subject headings and cross-references used in the filing and retrieval of documents. (Or indeed papers, certificates, letters, cards, records, texts, files, articles, essays and perhaps even manuscripts.)

The first example of this genre, Roget's Thesaurus, was published in 1852, having been compiled earlier, in 1805, by Peter Roget.

Although including synonyms, entries in a thesaurus should not be taken as a list of synonyms. The entries are also designed for drawing distinctions between similar words and assisting in choosing exactly the right word. Nor does a thesaurus entry define words. That work is left to the dictionary.

In Information Technology, a thesaurus represents a database or list of semantically orthogonal topical search keys. In the field of Artificial Intelligence, a thesaurus may sometimes be referred to as an ontology.
