Word History
Etymology
of uncertain origin
Note: A connection with game entry 4 is not well-motivated derivationally or phonetically. Also compared with regional French gambi, cambi "lame, bow-legged," though the late date of the word does not favor borrowing from such a source. The use of the word in English dialects to mean "clumsy" or "left-handed" (Somerset, Wiltshire, Gloucestershire, also gammy-handed) suggests that a word of different origin and meaning may have been influenced by game entry 4.
