History
Etymology
From buff + -er.
Etymology tree Old French buffeder. Middle English buff Proto-Indo-European *-yósder. Proto-Italic *-āzios Latin -āriusnom. Latin -āriusbor. Proto-Germanic *-ārijaz Proto-West Germanic *-ārī Old English -ere Middle English -ere English -er English buffer Agent noun from obsolete verb buff (“make a dull sound when struck”) (mid-16c.), from Old French buffe (“blow”). The “boatswain's mate” sense is said to be popularly explained by the mate being a “buffer”, that is intermediary, between officers and men, but various other explanations have also been proposed.
In reference to buff leather.
