close(v.)

(klōz), c. 1200, "to shut, cover in," from Old French clos- (past participle stem of clore "to shut, to cut off from"), 12c., from Latin clausus, past participle of claudere "to shut, close; to block up, make inaccessible; put an end to; shut in, enclose, confine" (always -clusus, -cludere in compounds), from PIE root *klau- "hook," also "peg, nail, pin," all things used as locks or bolts in primitive structures.

Also partly from Old English beclysan "close in, shut up." Intransitive sense "become shut" is from late 14c. Meaning "draw near to" is from 1520s. Intransitive meaning "draw together, come together" is from 1550s, hence the idea in military verbal phrase close ranks (mid-17c.), later with figurative extensions. Meaning "bring to an end, finish" is from c. 1400; intransitive sense "come to an end" is from 1826. Of stock prices, from 1860. Meaning "bring together the parts of" (a book, etc.) is from 1560s. Related: Closed; closing.

occlusion(n.)

"act or fact of being stopped up," 1640s, from Medieval Latin occlusionem (nominative occlusio), noun of action from past-participle stem of Latin occludere (see occlude). Dentistry sense "position of the two sets of teeth relative to each other when the mouth is closed" is from 1880.
