Pronunciation

Forms

clos (feminine close, masculine plural clos, feminine plural closes)[1] The noun is invariable (un clos, des clos).[1] Anglo-Norman also wrote it close and cloz.[2]

Etymology

It is inherited from Old French clos, the past participle of clore, inherited from Latin clausus (“closed”), past participle of claudō (“to shut”).[1][3][4] The adjective is recorded about 1130.[4][5] The masculine was used as a noun from about 1150, probably after Medieval Latin clausum (“enclosed cultivated field”) (721), the neuter participle used as a noun, which in classical Latin meant an enclosed space.[6][4][7]

Meyer-Lübke lists outcomes of the Latin word in other Romance speech, among them Milanese and Comasco forms for an enclosed plot or vineyard.[8]

Earliest recorded meaning

The adjective means “shut, closed” from about 1130.[4][5] The noun first appears about 1150 in the Roman de Thèbes for a piece of cultivated land fenced in.[6]

Semantic evolution

While the verb clore gave way to fermer, the participle stayed in use and entered figurative phrases such as à la nuit close “when night has fully fallen” and maison close, a euphemism for a brothel (1931).[4][5] It also means “finished, concluded”, of a meeting or a matter.[5]

The noun named an enclosed cultivated field, and especially a vineyard, as in the names of Burgundy wines.[5][9] In European French it has become old-fashioned for “field, meadow”, but in Quebec it is the usual word for an enclosure or field, notably a pasture, and prendre le clos is said of a car leaving the road.[4] In Louisiana French a clos is a cultivated field, fenced or not.[10] English took the noun as close “enclosure”, recorded in the late 13th century.[11]
