Thesaurus is a special purpose lexicon that aims to express the meaning of Modern Greek words or phrases through synonyms, antonyms and example uses. It is the result of more than four years systematic work. Its development was entirely computer-based (see Thesaurus Editor); its lemmata were organized and stored in a lexicographical database, a fact that made possible the conduct of tests and cross-checks that verified the correctness of the information content and the consistency of the inter-lemma references. The main characteristics of Thesaurus are:

  • It contains ~22.000 lemmata: 11.500 nouns, 5.150 adjectives, 3.500 verbs, 650 fixed phrases and 1.200 adverbs, prepositions and conjunctions.
  • Each lemma contains a list of discrete meanings. Synonyms, antonyms and example uses are grouped by meaning.
  • Headwords, their meanings and the synonyms/antonyms per meaning are accompanied by style attributes and domain categories.
  • For any word or phrase, which appears as a synonym, antonym or related phrase of some lemma, there is almost always (96%) a corresponding lemma in Thesaurus that describes it.
  • Any reference to a polysemous synonym or antonym is accompanied by a numeric index, which denotes the meaning number in the corresponding lemma of the synonym or antonym.
  • The lemmata also contain references to related fixed phrases (if any).
