A distinct area or group of people that is surrounded by or exists within a larger territory or population that is different from it.
From French 'enclave' (en- 'in' + clave, from Latin 'clavis' meaning 'key'), originally referring to a territory enclosed within another; the term evolved from medieval feudal geography.
