Forms
cailler[1] Old French coaillier, quailler.[2][1][3]
Etymology
It is inherited from Old French coaillier, inherited from Latin coāgulō (“to curdle, to congeal”).[4][5][6] Wiktionary gives a Vulgar Latin syncopated form *coaglō.[1] Littré explains the change by the loss of the short ⟨u⟩, which gave the Old French form and finally the modern one.[1][7] The Latin verb is formed on coāgulum (“rennet, curdled milk”), from cōgō (“to drive together”), a compound of co- and agō (“to drive”).[6] The learned doublet is coaguler.[1][2]
Cognate with Italian quagliare, Occitan calhar, Spanish cuajar, Portuguese coalhar and Romanian închega.[8][9]
Earliest recorded meaning
The Oxford Psalter (early 12th century) has coailliez est, sicume lait “it is curdled like milk”, of the heart: the verb meant to curdle or congeal.[4][7][3]
Semantic evolution
The verb, used intransitively, transitively and reflexively, has always meant to curdle or clot, of milk and blood; the participle lait caillé gave the noun caillé in the early 14th century.[6][4] In familiar speech of the early 20th century, with a person as subject, it took the sense “to be frozen with cold” (on caille, on se caille), and impersonally ça caille “it is freezing”.[6][10]
