Enclave comes from French enclaver, meaning "to enclose," which itself is based on the Latin noun clavis, meaning "key." Clavis opened the door to a few other English words, some of which might seem unlikely relatives of enclave. For example, clavicle, the word for the bone that joins the breastbone and the shoulder blade, and the musical sign clef.
