churn

Etymology

It is inherited from Middle English chirne, also cherne and, chiefly in the north, kirne,^[2][3] inherited from Old English cyrin, also cyrn,^[4][5][6][7] inherited from Proto-Germanic *kirnijǭ.^[3][7][8] It is cognate with Middle Low German kerne, Middle Dutch kerne, Dutch karn, Middle High German kern and Old Norse kirna (Swedish kärna, Danish kjerne).^{[8][9][10][3]} Köbler and Hoad call the origin of the Germanic word unknown,^[11][7][3] but most dictionaries think it is related to kernel and corn, from the grainy look that cream takes on as it is churned.^{[8][5][12][13]} Klein traces it to a Germanic word for cream, properly "the kernel of the milk",^[9] and Orel takes the Germanic noun as probably related to the word for kernel, Proto-Germanic *kernōn.^[14] The verb is chyrnen, formed from the noun;^[8][5][10] Old English has no verb, but Dutch karnen has the same sense.^[10]

Earliest recorded meaning

A vessel for making butter: in an Old English glossary, where cyrin translates Latin sinum.^[6][10] Barnhart dates the Old English word to about 1000, and finds kirne in 1339 and chirne about 1350.^[3][2]

Semantic evolution

The noun named the butter churn from Old English on; from 1747 it was extended to other vessels or tools that resembled it, such as a pump used in mines,^[10] and in Britain it is also a large can for carrying milk.^[15][16] The verb, first recorded about 1440 in the Promptorium Parvulorum for making butter,^[10][8][3] was widened in the late 17th century to stirring or agitating any liquid violently (1697, Dryden's Aeneid), and became intransitive in 1735.^[10][8] From 1846 the mind, feelings or stomach could be churned, and churn out, to produce writing or goods mechanically and in quantity, appears in the early 20th century: 1902 in Etymonline, 1912 in Rupert Brooke's letters in the OED.^[10][8] In business, first in the United States, churn has since 1977 meant the loss and replacement of a company's customers or subscribers.^[10][15] In Lancashire the daffodil was called churn,^[10] and the English Dialect Dictionary records local compounds such as churn-staff and churn-supper, a harvest-home supper.^[17]
