Origin and history of vinegar

vinegar(n.)

diluted impure acetic acid, early 14c., vinegre, usually "wine vinegar," from Anglo-French vinegre, Old French vinaigre "vinegar," from vin "wine" (from Latin vinum; see wine (n.)) + aigre "sour" (see eager). In Latin, it was vinum acetum "wine turned sour," acetum for short (see acetic), also used figuratively for "wit, shrewdness;" and compare Greek oxos "wine vinegar," which is related to oxys "sharp" (from PIE root *ak- "be sharp, rise (out) to a point, pierce"). Related: Vinegary; vinegarish.

Entries linking to vinegar

1808 (in acetic acid), from French acétique "pertaining to vinegar, sour, having the properties of vinegar," from Latin acetum "vinegar" (properly vinum acetum "wine turned sour;" see vinegar), originally the past participle of acere "be sharp; be sour" (related to acer "sharp," from PIE root *ak- "be sharp, rise (out) to a point, pierce").

late 13c., "strenuous, ardent, fierce, angry," from Old French aigre "sour, acid; harsh, bitter, rough; eager greedy; lively, active, forceful," from Vulgar Latin *acrus (source also of Italian agro, Spanish agrio), from Latin acer "keen, sharp, pointed, piercing; acute, ardent, zealous" (from PIE root *ak- "be sharp, rise (out) to a point, pierce").

The meaning "full of keen desire" (early 14c.) seems peculiar to English. Into 19c. the word kept a secondary meaning of "pungent, sharp-edged" (as in Shakespeare's "The bitter clamour of two eager tongues," in "Richard II"). Related: Eagerly; eagerness. Eager beaver "glutton for work" [OED, 1989] is from 1943, U.S. armed forces slang.
