coach: [16] Coach is one of the few English words borrowed from Hungarian. It comes (via French coche and German kutsche) from Hungarian kocsi, an adjective meaning ‘of Kocs’ (Kocs is a village in north-east Hungary, between Budapest and Györ, where carriages, carts, etc were made). In Hungarian the original full form was kocsi szeker ‘cart from Kocs’. The modern sense ‘instructor, trainer’ originated in 19th-century university slang, the notion being that the student was conveyed through the exam by the tutor as if he were riding in a carriage.
