Etymology

Origin of butter

before 1000; Middle English; Old English butere < Latin būtȳrum < Greek boútȳron

Explanation

Butter is a creamy spread made from milk fat. Your favorite breakfast might be hot toast slathered with butter. The process of making butter involves churning cream until the fats coagulate and become creamy and pale yellow. Butter is sometimes salted, and usually formed into sticks for cooks to use in frying, baking, and spreading on corn on the cob and baked goods. To do this is to butter your bread. The Greek root word is boutyron, literally "cow cheese," from bous, "cow."
