Etymology

Etymology 1

From Middle English coagulaten (“(of blood) to clot or, make blood coagulate; (of tissue) to consolidate”), from coagulat(e) (“coagulated; (blood) clotted; (milk) curdled; (humor) thickened, viscous; (material) solidified, cohesive; (wine) boiled down, reduced”, also used as the past participle of coagulaten) + -en (verb-forming suffix), borrowed from Latin coāgulātus, the perfect passive participle of coāgulō (“to curdle, coagulate”), from coāgulum (“a means of curdling, rennet”), from cōgō (“bring together, gather, collect”) + -ulum (forms instrument nouns), from co- (“together”) + agō (“do, make, drive”). Doublet of quail. Displaced native Middle English irennen, from Old English ġerinnan, but not native curdle.

Etymology 2

From Middle English coagulat(e) (“coagulated; (blood) clotted; (milk) curdled; (humor) thickened, viscous; (material) solidified, cohesive; (wine) boiled down, reduced”), also used as the past participle of coagulaten and of coagulate in Early Modern English, see -ate (adjective-forming suffix) and Etymology 1 for more.

Etymology 3

From New Latin coāgulātum, substantivized from the nominative neuter singular of coāgulātus, see -ate (noun-forming suffix) and Etymology 1 for more.
