coach

Etymology

Borrowed from Middle French coche, from German Kutsche, from Hungarian kocsi. According to historians, the coach was named after the small Hungarian town of Kocs, which made a livelihood from cart building and transport between Vienna and Budapest. The meaning "instructor/trainer" is from Oxford University slang (c. 1830) for a "tutor" who "carries" one through an exam; the athletic sense is from 1861.
