Pronunciation

  • UK: /kənˈsɜː.və.tɹi/[1]
  • US: /kənˈsɝ.vəˌt(ɔ.)ɹi/[1]

Etymology

It is borrowed from Late Latin cōnservātōrium (“that which preserves”),[2][3][4][1] the noun use of the neuter of cōnservātōrius (“preservative”),[2][3][5] from Latin cōnservātus, the past participle of cōnservō (“to keep, preserve”).[2][5][6] The Latin verb is formed from com- and servō (“to keep watch, maintain”), from Proto-Indo-European *ser- (“to protect”).[7] Etymonline derives the first sense from the adjective conservatory, from cōnservātor (“keeper, preserver”).[7] The sense of a school of music follows Italian conservatorio and French conservatoire.[2][3][7][5] Middle English already had servatorie (“fish pond, reservoir”), from Medieval Latin servātōrium.[7]

Earliest recorded meaning

Something that preserves, a preservative: 1563, in the “Second Tome of Homilies”, a sense obsolete by 1660.[2][3] Etymonline dates it to the 1560s.[7]

Semantic evolution

The post-classical Latin word meant something that preserves from the 4th century, a fish pond from the 14th, and a greenhouse for tender plants by 1622 in British use.[2] In English it meant a place where things are kept safe, a storehouse, from 1624,[2][7][5] and Bacon used it in 1626 for an ice house and a reservoir.[2] Johnson (1755) defined it as a place where anything is kept in a way suited to its nature, as fish in a pond or corn in a granary.[8] The greenhouse sense dates from 1664, in Evelyn's “Sylva”,[2][7] and in modern use a conservatory is often a glazed room attached to a house and used as a living room.[2][9] The musical sense came from Italy, where a conservatorio was a hospital for foundlings and orphans that taught music: English used the word for such a hospital from 1620,[2][7] and for a school of music from 1789 according to the OED, or 1805 according to Etymonline.[2][7] The French took the institution over after the Revolution,[7] and the music-school sense is now chiefly American;[2] Collins gives it as another word for conservatoire.[9]
