1885, verbal noun from ski (v.).
THE new sport which has lately been introduced at Beloit is skeeing. They are long ash planks, carefully and turned up at the end, and are warranted to take down hill quicker than a wink. After some practice performers become very expert, and the speed with which they go is something surprising. [Beloit College, Wisconsin, Round Table, Dec. 18, 1885]
"a buffoon; a zany; a jack-pudding" [Johnson], "One whose business it is to make sport for others by jokes and ridiculous posturing" [Century Dictionary], according to OED, in early use properly a mountebank's assistant, 1670s, from merry + masc. proper name Andrew, but there is no certain identification with an individual, and the name here may be generic.
c. 1300, dalien, "to speak seriously, commune;" late 14c., "to talk intimately, converse politely," possibly from Anglo-French dalier "to amuse oneself," Old French dalier, dailer, which is of uncertain origin. Sense of "waste time" in any manner emerged by late 14c.; that of "to play, sport, frolic; flirt, engage in amorous exchanges" is from mid-15c. Meaning "to linger, loiter, delay (intransitive)" is from 1530s. Related: Dallied; dallying.
mid-14c., "jest, make light of something;" mid-15c., "ridicule, mock," from a noun meaning "contemptuous ridicule" (c. 1300), which is from a Scandinavian source such as Old Norse skaup, skop "mockery, ridicule," Middle Danish skof "jest, mockery;" perhaps from Proto-Germanic *skub-, *skuf- (source also of Old English scop "poet," Old High German scoph "fiction, sport, jest, derision"), from PIE *skeubh- "to shove" (see shove (v.)). Related: Scoffed; scoffing.
