Etymology

It is inherited from Middle English curlen,[2][3][4] a form with the r and the vowel transposed (a metathesis) of crullen, also crollen,[2][4][5][6] from the adjective crul (“curly”), also crol and crulle.[7][2][8] The OED notes that the early instances are of the past participle, found in the 14th century as crolled and crulled, and calls the origin uncertain.[9][10] Ayto, Hoad and the Oxford Dictionary of English take the adjective as borrowed from Middle Dutch krul (“curly”),[6][11][12] and Merriam-Webster and the American Heritage Dictionary think it probably Middle Dutch or perhaps Middle Low German;[3][4] Barnhart thinks it probably developed from an unrecorded Old English word, and Etymonline gives both views.[2][8] The Middle Dutch word is from Proto-Germanic *kruzlǭ (“bent or crooked object, curl”),[8][6][13] also the source of East Frisian Low German krull (“lock of hair”), Middle High German krol, Norwegian krull and Danish krølle (“curl”),[8][2][5] and is related to krūs, modern German kraus (“curly”).[6][2][11] Barnhart traces the set to Proto-Indo-European *grus-lo-.[2] Through modern Dutch krul, the same word gave English cruller.[6]

Earliest recorded meaning

The adjective crul, curly, of hair, is recorded from about 1300,[8][2][7] and Chaucer's squire in the Canterbury Tales has "lokkes crulle as they were leyd in presse".[14][7] The verb, to bend or twist hair into ringlets, is first recorded in 1447, in O. Bokenham's Lyvys of Seyntys,[9] and Barnhart finds curlen in the Promptorium Parvulorum in 1440 and crollen about 1380.[2]

Semantic evolution

The verb began with hair and spread to anything bent or coiled into a spiral (from 1562), to the intransitive "form curls", first of hair (1530),[9][8] and to the curling of the lip in contempt, from 1816 in W. Scott.[9] The noun, a ringlet of hair, follows the verb: the OED's first quotation is from Shakespeare's Hamlet (1604; 1602 in Barnhart),[9][2][8] although Merriam-Webster gives 1578.[3] By the 1610s it was used of anything of a similar spiral or wavy form.[8][9] Technical senses followed: an eddy in a stream for anglers (1766), a disease of potatoes in which the shoots curl up (1790), the mathematical curl of a vector, from J. C. Maxwell (1873), a body exercise (1944) and in surfing the curved top of a breaking wave (1962).[9][8] The game of curling, recorded from 1620, is named after the curving path of the stones, according to Weekley,[2][14] and the verb "to play at curling" is from 1715, in Scotland.[8][15] In northern English and Scottish dialect a curl-doddy was the blue scabious or a fir cone, among other things.[15]
