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 that are related by similar 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.

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.
