cool (adj.): Old English col "not warm" (but usually not as severe as cold), also, of persons, "unperturbed, undemonstrative," from Proto-Germanic *koluz (cognates: Middle Dutch coel, Dutch koel, Old High German kuoli, German kühl "cool," Old Norse kala "be cold"), from PIE root *gel- "cold, to freeze" (see cold (adj.)).

Applied since 1728 to large sums of money to give emphasis to amount. Meaning "calmly audacious" is from 1825. Slang use for "fashionable" is 1933, originally Black English; modern use as a general term of approval is from late 1940s, probably from bop talk and originally in reference to a style of jazz; said to have been popularized in jazz circles by tenor saxophonist Lester Young. Related: Coolly.

coolth (n.): 1540s, from cool on the model of warmth. It persists, and was used by Pound, Tolkien, Kipling, etc., but it never has shaken its odor of facetiousness and become standard.
coomb (n.): also combe, "deep hollow or valley, especially on flank of a hill," mainly surviving in place names, from Old English cumb, probably a British word, from Celtic base *kumbos (compare Welsh cwm in same sense). Cambridge Dictionary of English Place-Names says, "This is usually taken to be a Celtic loan ... but there was also OE cumb 'vessel, cup, bowl,'" which was "probably used in a transferred topographical sense reinforced in western districts by cwm."
coon (n.): short for raccoon, 1742, American English. It was the nickname of Whig Party members in U.S. c. 1848-60, as the raccoon was the party's symbol, and it also had associations with frontiersmen (who stereotypically wore raccoon-skin caps), which probably ultimately was the source of the Whig Party sense (the party's 1840 campaign was built on a false image of wealthy William Henry Harrison as a rustic frontiersman).

The insulting U.S. meaning "black person" was in use by 1837, said to be ultimately from Portuguese barracoos "building constructed to hold slaves for sale." No doubt boosted by the enormously popular blackface minstrel act "Zip Coon" (George Washington Dixon) which debuted in New York City in 1834. But it is perhaps older (one of the lead characters in the 1767 colonial comic opera "The Disappointment" is a black man named Raccoon). Coon's age is 1843, American English, probably an alteration of British a crow's age.
coop (n.): "small cage for poultry," mid-14c., from Old English cype, cypa "basket, cask," akin to Middle Dutch kupe, Swedish kupa, and all probably from Latin cupa "tub, cask," from PIE *keup- "hollow mound" (see cup (n.)).
coop (v.): 1560s, from coop (n.). Related: Cooped; cooping.
cooper (n.): "craftsman who makes wooden vessels," attested from late 12c. as a surname, either from Old English (unattested) or from a Low German source akin to Middle Dutch cuper, East Frisian kuper, from Low German kupe (German Kufe) "cask," cognate with Medieval Latin cupa (see coop (n.)).
A dry cooper makes casks, etc., to hold dry goods, a wet cooper those to contain liquids, a white cooper pails, tubs, and the like for domestic or dairy use. [OED]
