The word “coach” is thought to have first entered the English language in 1550s and according to Etymonline, this referred to a “large kind of four-wheeled, covered carriage”.  The English word derived from the Hungarian village of Kocs, where a coach (“kocsi”) was first made, and through French and German iterations in the next century, “coche” and “kotsche” respectively.  The coach would have been drawn by horses which offers another travelling idiom to the Twentieth Century term “coaching.”
