conserve

Etymology

The verb is inherited from Middle English conserven,^[2][3][4] borrowed from Old French conserver (“to protect, preserve”),^{[5][6][7][8][9]} and partly directly borrowed from Latin cōnservō (“to keep safe, preserve, keep intact”).^[6][10] The Latin verb is formed from com-, here an intensive prefix, and servō (“to keep, watch over, preserve”),^[5][4][7][8] from Proto-Indo-European *ser- (“to protect”).^[5][4] Barnhart and Klein compare Avestan haurvaiti (“he keeps watch, guards”).^[7][9] Ayto holds that this verb is not related to servus (“slave”), the source of serve and servant,^[11] but Dictionary.com calls them akin.^[10] The Anglo-Norman verb is recorded from 1284 with the sense "to preserve".^[12] The noun is partly borrowed from Middle French conserve (“a preparation preserved in sugar”), from conserver, and partly a use of the English verb.^[6][7][13]

Earliest recorded meaning

To keep safe, preserve from loss or harm: about 1380, in Chaucer's Canterbury Tales, according to Barnhart;^[7] the OED's first record is from before 1398, in Trevisa's translation of Bartholomaeus Anglicus.^[6] Chaucer uses the verb ten times.^[14] The noun is recorded from before 1393, in Gower's Confessio Amantis, for something that preserves and for a sweet or medicinal preparation of plants in sugar.^[6][7]

Semantic evolution

From the start the verb meant both keeping a thing alive or intact and keeping a condition or institution unchanged (Chaucer, about 1390).^[6] Until the mid-17th century it could also mean to keep a promise or observe a custom, following the French sense.^[6] The kitchen sense, to preserve fruit in sugar, dates from 1538 and is now mainly American.^[6] From 1593 it was used of husbanding a resource and avoiding waste, a sense later influenced by conservation, which also shaped the 20th-century uses: protecting the natural environment (1908) and preserving or restoring old artefacts (1964).^[6] Physics gave it the sense of keeping the total of a quantity such as energy unchanged (1874).^[6][3] The noun's medicinal and confectionary sense of plants preserved in sugar (before 1393) narrowed to jam or preserves;^[6][7] Johnson (1755) defined it as a sweetmeat of fruit juices boiled with sugar.^[15] Its other old senses, a preservative, a store or hoard, and a conservatory for plants, have died out.^[6][13]
