Etymology: Butter has a Greek name built from cow's milk and cheese. Ancient Greek "boûs" meant cow (the same root that gives "bovine"), and "turós" meant cheese, so "boútūron" was literally "cow-cheese." The Romans borrowed it as "būtȳrum," and the word passed through Old English and Middle English as "butere" before becoming modern "butter." Fat has a far older and plainer history in English, descending from the same ancestral root as the Old English "fættan," meaning to fatten or to become plump. The word then took on the sense of a rich, oily substance. Butterfat is a simple compound: it names the fat that is separated out from cream when it is churned into butter. Its name is an English coinage built from two ordinary words, not an old term.
