local: [15] Latin locus meant ‘place’ (it became in due course French lieu, acquired by English in the 13th century, and was itself adopted into English as a mathematical term in the 18th century). From it was derived the verb locāre ‘place’, source of English locate [18] and location [16], and the post-classical adjective locālis, from which English gets local. The noun locale is a mock frenchification of an earlier local [18], an adoption of the French use of the adjective local as a noun.
