英文词源

promulgate: promulgate: [16] Promulgate owes its existence to an analogy drawn by the Romans between ‘milking’ and ‘bringing out into the light of day’. The Latin verb for ‘milk’ was mulgēre (source of English emulsion). It was used metaphorically for ‘cause to emerge’, and combination with the prefix prō- ‘forth, out’ produced prōmulgāre ‘make known publicly, publish’ – whence English promulgate.

promulgate (v.): 1520s, from Latin promulgatus, past participle of promulgare "make publicly known, propose openly, publish," perhaps altered from provulgare, from pro- "forth" (see pro-) + vulgare "make public, publish." Or the second element might be from mulgere "to milk" (see milk (n.)), used metaphorically for "cause to emerge;" "a picturesque farmers' term used originally of squeezing the milk from the udder" [L.R. Palmer, "The Latin Language"]. Related: Promulgated; promulgating. The earlier verb in English was promulge (late 15c.).
