- galleon (n.)
- large ship, 1520s, from Old French galion "little ship" (13c.), from Spanish galeón "galleon, armed merchant ship," from Byzantine Greek galea "galley" (see galley) + augmentative suffix -on. In English use, especially of Spanish ships involved in the American trade.
GALLEON. The accepted term for the type of ship which the Spaniards used in 1588; that is, an armed merchantman of exceptional quality, combining the strength of the mediaeval trader with some of the finer lines and fighting features of the GALLEY. [Sir Geoffrey Callender, "Sea Passages," 1943]
