Pronunciation

  • IPA: /ˈkləʊ.ʒə(ɹ)/ (UK); /ˈkloʊ.ʒɚ/ (US)[1]

Etymology

It is Middle English, borrowed from Old French closure (“enclosure, fastening, wall, fence”),[2][3][4] from Late Latin clausura (“lock, fortress, a closing”),[2][5] from the past participle stem of claudere (“to close”) (see close).[2][4]

Earliest recorded meaning

That which encloses, a fence or barrier: about 1386 in the OED, the late 14th century in Etymonline.[6][2]

Semantic evolution

An entrenchment or fort (before 1400–50) and an enclosed place (1386) are obsolete senses.[6] The act of enclosing or confining is from about 1420,[6] and the act of closing or bringing to a close from 1600 (the early 15th century in Etymonline).[6][2] Hoad treats the sense conclusion as a new formation on close in the 16th century.[5] In legislation it is the stopping of debate by a vote (compare cloture).[2][7] In Gestalt psychology, the tendency to form ordered, satisfying wholes is from 1924,[2] and the chiefly American sense, a feeling of resolution after a painful event, is later.[7]
