clipper (n.)youdaoicibaDictYouDict
late 14c., "sheepshearer;" early 15c., "a barber;" c. 1300 as a surname; agent noun from Middle English clippen "shorten" (see clip (v.1)). The type of fast sailing ship so called from 1823 (in Cooper's "The Pilot"), probably from clip (v.1) in sense of "to move or run rapidly," hence early 19c. sense "person or animal who looks capable of fast running." Perhaps originally simply "fast ship," regardless of type:
Well, you know, the Go-along-Gee was one o' your flash Irish cruisers -- the first o' your fir-built frigates -- and a clipper she was! Give her a foot o' the sheet, and she'd go like a witch--but somehow o'nother, she'd bag on a bowline to leeward. ["Naval Sketch-Book," by "An officer of rank," London, 1826]
The early association of the ships was with Baltimore, Maryland. Perhaps influenced by Middle Dutch klepper "swift horse," echoic (Clipper appears as the name of an English race horse in 1831). In late 18c., the word principally meant "one who cuts off the edges of coins" for the precious metal.

Clipping or Cutting Down from Behind. -- This is to be ruled under unnecessary roughness, and penalized when it is practiced upon "a man obviously out of the play." This "clipping" is a tendency in the game that the committee is watching anxiously and with some fear. ["Colliers," April 10, 1920]

"a sharp noise," also "latch, bolt of a door," from Old French cliquer "click, clatter, crackle, clink," 13c., echoic. Apparently this word was at one time treated in French as the equivalent of claque (q.v.) and partook of that word's theatrical sense.

clitoris (n.)youdaoicibaDictYouDict
"erectile organ of female mammals," 1610s, coined in Modern Latin from Late Greek kleitoris, a diminutive, but the exact sense intended by the coiners is uncertain. Perhaps from Greek kleiein "to sheathe," also "to shut," in reference to its being covered by the labia minora. The related Greek noun form kleis has a second meaning of "a key, a latch or hook (to close a door);" see close (v.), and compare slot (n.2).

Alternatively, perhaps related to Greek kleitys, a variant of klitys "side of a hill," itself related to klinein "to slope," from the same root as climax (see lean (v.)), and with a sense of "little hill." Some ancient medical sources give a supposed Greek verb kleitoriazein "to touch or titillate lasciviously, to tickle" (compare German slang der Kitzler "clitoris," literally "the tickler"), but the verb is likely from the anatomy in this case.

The anatomist Mateo Renaldo Colombo (1516-1559), professor at Padua, claimed to have discovered it ("De re anatomica," 1559, p. 243). He called it amor Veneris, vel dulcedo "the love or sweetness of Venus." It had been known earlier to women.
cloaca (n.)youdaoicibaDictYouDict

Use in biology, in reference to eliminatory systems of lower animals, is from 1834. Related: Cloacal (1650s); cloacinal (1857).
cloak (n.)youdaoicibaDictYouDict
late 13c., "long, loose outer garment," from Old North French cloque (Old French cloche, cloke) "travelling cloak," from Medieval Latin clocca "travelers' cape," literally "a bell," so called from the garment's bell-like shape (the word is thus a doublet of clock (n.1)). An article of everyday wear in England through 16c., somewhat revived 19c. as a fashion garment. Cloak-and-dagger (adj.) attested from 1848, said to be ultimately translating French de cape et d'épée, suggestive of stealthy violence and intrigue.
