Forms
fermentum n (genitive fermentī); second declension[1]
Etymology
It is inherited from Proto-Italic *fer(a)mentom, inherited from Proto-Indo-European *bʰer(H)-mn̥ (“ferment”).[2][1] Cognate with Old English beorma (“yeast, barm”).[2][3] De Vaan finds it most attractive to derive it from the simple root *bʰr(H)- behind ferveō “to boil” and dēfrutum “boiled-down must”, though the form and meaning of the root are unclear.[2] Lewis and Short and Gaffiot take it as a contraction of *fervimentum, from ferveō.[4][5]
Earliest recorded meaning
De Vaan dates it from Plautus.[2][6] Köbler dates Plautus c. 250–184 BC.[6]
Semantic evolution
It meant the process of fermentation, and the substance that causes it, leaven, yeast, as Virgil's northern peoples who make a wine-like drink with ferment.[3][5] Celsus speaks of bread without leaven, and the Vulgate uses it of the leaven of the law.[4] By transfer it meant a drink of fermented barley, and figuratively anger or passion.[5][7]
In Medieval Latin it was a piece of the eucharistic bread sent by the bishop to parish priests, leavened bread, and a fermenting poultice.[8][9] English ferment came in the late 14th century.[7]
