Ahoy (/ÉËhÉÉª/) is a signal word used to signal a ship or boat, stemming from the Middle English cry, 'Hoy!'. The word had fallen into obsolescence before rising from obscurity as the sport of sailing rose in popularity. 'Ahoy' can also be used as a greeting, a warning, or a farewell.
A buoy (/ËbÉÉª/ , also /ËbwÉÉª/ or US /ËbuËiË/) is a floating device that can have many purposes. It can be anchored (stationary) or allowed to drift with the sea wave. The word, of Old French or Middle Dutch origin, is (in British English) now most commonly pronounced /ËbÉÉª/ (identical with boy, as in buoyant).
