Past tense of 'butler': to work as or perform the duties of a butler; to serve.
From butler (Middle English, from Old French bouteillier, a bottle-bearer or wine-servant) + -ed (past tense marker). The role evolved from managing wine cellars to overseeing entire households.
Butlers started as literally the people who managed bottles in medieval households, but their status grew so much that the word became synonymous with refined domestic service—a perfect example of how job titles can climb the social ladder.
