Latinate feminine form of Felix. It was popular in Britain in the medieval period (with the vernacular forms Felice, Felis), but by the 16th century it had become confused with Phyllis. In modern times it is in only occasional use.
English: 1. variant of Game. 2. from Anglo-Norman French gambon ‘ham’, a diminutive of gambe, Norman-Picard form of Old French jambe ‘leg’ (Late Latin gamba), hence probably a nickname for someone with some peculiarity of the legs or gait.
