The word "enclave" originates from French, derived from the Old French verb enclaver (to enclose), which combines the prefix en- (meaning "in") with claver (from Latin clavis, meaning "key"). The metaphor of a "key" evolved to signify something locked or enclosed within a larger space. Initially used in geography to describe territories surrounded by foreign lands, it later expanded to computing and sociology.
