conservancy

Etymology

The OED takes it either borrowed from Medieval Latin conservantia (“preservation, maintenance”), recorded from the 13th century in British sources, or as formed from English conserve + -ancy;^[2] the Latin noun is from cōnservāns, the present participle of cōnservō (“to keep, preserve”).^[2][3][4] Merriam-Webster, Hoad, the Shorter Oxford and the Oxford Dictionary of English explain it as an alteration of the earlier conservacy, recorded from 1434, by assimilation to words in -ancy;^[5][6][7][8] that word is from Anglo-Norman conservacie and Medieval Latin conservātia, a by-form of cōnservātiō (conservation).^[6][8][2] The Latin verb is formed from com-, perhaps here an intensive prefix, and servō (“to keep watch, maintain”),^[3] from Proto-Indo-European *ser- (“to protect”).^[3]

Earliest recorded meaning

The action of conserving or keeping something safe: before 1500, in a translation of the Secreta Secretorum.^[2] Etymonline dates the word to 1755, in the sense of a commission with jurisdiction over a port or river.^[3]

Semantic evolution

The general sense of protection is now rare.^[2] The word became attached to the official care of waterways from 1613, and to the official body in charge of a waterway or port, regulating fisheries and navigation, from 1618, as in the Thames Conservancy.^[2][5] Johnson (1755) knew it only for the courts held by the Lord Mayor of London to preserve the fishery of the Thames.^[9] From the 19th century it was extended to the official care of forests: Etymonline dates this to 1859, in a report on the protection of bo trees in Ceylon.^[3][7] The sense of an organization that protects nature or undeveloped land is recorded from 1949 in Etymonline,^[3] and Merriam-Webster and Collins record conservancy also as a word for the conservation of natural resources.^[5][10]
