Synonyms Vocabulary, Dictionary, Glossary, Lexicon, Nomenclature. A vocabulary, in the present use, is a list of words occurring in a specific work or author, generally arranged alphabetically, concisely defined, and appended to the text; whereas we generally apply the term dictionary to a word-book of all the words in a language or in any department of art or science, without reference to any particular work: thus, we speak of a vocabulary to Cæsar, but of a dictionary of the Latin language, or of architecture, chemistry, etc. An exception to this may be where the words of an author are so fully treated, by derivation, illustration, etc., as to seem to amount to more than a vocabulary: as, a Homeric dictionary. A glossary is yet more restricted than a vocabulary, being a list and explanation of such terms in a work or author as are peculiar, as by being technical, dialectal, or antiquated: as, a glossary to Chaucer, Burns, etc; a glossary of terms of art, philosophy, etc. Lexicon was originally and is often still confined to dictionaries of the Greek or Hebrew tongues, but it is also freely applied to a dictionary of any dead or merely foreign language: as, a German-English lexicon. A nomenclature is a complete list of the names or technical terms belonging to any one division or subdivision of science.
