Pronunciation

Etymology

It is borrowed from French cache (“hiding place”),[2][3][4][5][6] a noun formed from cacher (“to hide”),[2][4][7][8] which is recorded from the 13th century.[8] Etymonline and Barnhart trace the English use to the French of Canada, where trappers called a hidden store of provisions a cache from the 1660s.[8][9] The French verb comes from Vulgar Latin *coācticō (“to press together, store up”),[10][3][8][7][11] a frequentative of Latin coāctō (“to constrain, compel”), itself from cōgō (“to drive together, compel”), formed from com- (“together”) and agō (“to drive”).[8][7][3] Partridge explains the change of sense: pressing something into a small space makes it less noticeable, and so hides it.[12] The word is related to cogent and cachet.[7][10]

Earliest recorded meaning

A hole or mound made by pioneers and Arctic explorers to hide stores of provisions or ammunition: 1797, in the journal of Charles Chaboillez.[2] Barnhart, Etymonline and Merriam-Webster also date the noun to 1797, as an American word.[9][8][3] Weekley calls it a 19th-century word from French-Canadian trappers that Drake had used once,[13] and Dictionary.com dates it to 1585–95.[11]

Semantic evolution

The word spread with the North American fur trade and Arctic exploration.[8][2] The verb, to put provisions in a cache, is recorded in 1805 in the journals of the Lewis and Clark expedition,[2][9][3] and the noun was soon used of the stored goods themselves (1836, in George Back's narrative of his Arctic expedition),[2] which Barnhart puts in the 1830s.[9] From 1860 it was used of any hiding place for goods or treasure.[2] In 1968 computer scientists took it for a small, fast memory that holds the data a processor uses most often,[2][4] and the verb followed in this sense in 1983.[2]
