John Wilkins, An Essay Towards a Real Character, and a Philosophical Language and Alphabetical Dictionary (1668) are a "regular enumeration and description of all those things and notions to which names are to be assigned".The study of synonyms became an important theme in 18th-century philosophy, and Condillac wrote, but never published, a dictionary of synonyms. In Sanskrit, the Amarakosha is a thesaurus in verse form, written in the 4th century. In antiquity, Philo of Byblos authored the first text that could now be called a thesaurus. Peter Mark Roget, author of Roget's thesaurus. It was Roget who introduced the meaning "collection of words arranged according to sense", in 1852. Until the 19th century, a thesaurus was any dictionary or encyclopedia, as in the Thesaurus Linguae Latinae ( Dictionary of the Latin Language, 1532), and the Thesaurus Linguae Graecae ( Dictionary of the Greek Language, 1572). The word thēsauros is of uncertain etymology. The word "thesaurus" comes from Latin thēsaurus, which in turn comes from Greek θησαυρός ( thēsauros) 'treasure, treasury, storehouse'. Writers sometimes use thesauri to avoid repetition of words - elegant variation - which is often criticized by usage manuals: "writers sometimes use them not just to vary their vocabularies but to dress them up too much".
INFORMATION SYNONYM MANUALS
Usage manuals such as Fowler's Dictionary of Modern English Usage or Garner's Modern English Usage often prescribe appropriate usage of synonyms. Some synonym dictionaries are primarily concerned with differentiating synonyms by meaning and usage. Some thesauri and dictionary synonym notes characterize the distinctions between similar words, with notes on their "connotations and varying shades of meaning". Most thesauri do not include definitions, but many dictionaries include listings of synonyms. While some works called "thesauri", such as Roget's Thesaurus, group words in a hierarchical hypernymic taxonomy of concepts, others are organized alphabetically or in some other way. The word 'thesaurus' was used in 1852 by Peter Mark Roget for his Roget's Thesaurus. Synonym dictionaries have a long history.
