vinegar
UK: ˈvɪnɪɡə | US: ˈvɪnɪɡər
n. a sour liquid made from fermented wine, cider, or malt, used as a condiment or preservative
n. (figuratively) a sharp or bitter quality in speech or mood
The word "vinegar" traces back to Old French vyn egre ("sour wine"), combining vin (wine) and aigre (sour). It reflects the process of wine turning acidic due to bacterial fermentation. The Latin roots vinum and acer highlight its dual origin as a product of wine and its sharp taste. Over time, the term expanded metaphorically to describe tartness in language or temperament.
