skank (n.)

skat (n.)
card game, 1864, from German Skat (by 1838), from earlier scart (said to have been a term used in the old card game called taroc, which was of Italian origin), from Italian scarto "cards laid aside," which is said to be a back-formation from scartare, from Latin ex- "off, away" + Late Latin carta (see card (n.1)). The German game is perhaps so called because it is played with a rump deck, or because two cards are laid aside at the start of the game, or because discarding is an important part of the game. Compare French card game écarté, literally "cards removed."
skate (n.1)
"type of flat, cartilaginous fish, a kind of ray," mid-14c., from a Scandinavian source such as Old Norse skata "skate," Danish skade, Faeroese skøta, of unknown origin.
skate (n.2)
"ice skate," 1660s, skeates "ice skates," from Dutch schaats (plural schaatsen), a singular mistaken in English for plural, from Middle Dutch schaetse. The word and the custom were brought to England after the Restoration by exiled followers of Charles II who had taken refuge in Holland.

The Dutch word is from Old North French escache "a stilt, trestle," related to Old French eschace "stilt" (French échasse), from Frankish *skakkja "stilt" or a similar Germanic source (compare Frisian skatja "stilt"), perhaps literally "thing that shakes or moves fast" and related to root of Old English sceacan "to vibrate" (see shake (v.)). Or perhaps [Klein] the Dutch word is connected to Middle Low German schenke, Old English scanca "leg" (see shank). Sense alteration in Dutch from "stilt" to "skate" is not clearly traced. Sense in English extended to roller-skates by 1876. Meaning "an act of skating" is from 1853.
skate (v.)
1690s, "to ice-skate," from skate (n.2). U.S. slang sense of "to get away with something" is attested from 1945. Related: Skated; skating.

skedaddle (v.)
"to run away," 1861, American Civil War military slang, of unknown origin, perhaps connected to earlier use in northern England dialect with a meaning "to spill." Liberman says it "has no connection with any word of Greek, Irish, or Swedish, and it is not a blend" [contra De Vere]. He calls it instead an "enlargement of dial. scaddle 'scare, frighten.'" Related: Skedaddled; skedaddling. As a noun from 1870.
Skee-Ball (n.)
1909, proprietary name (Skee-Ball Alley Company, Philadelphia, Pa., U.S.), the first element said to represent the old alternative spelling of ski (v.).

skeet (n.)

skeletal (adj.)
1849, from skeleton + -al (1). Related: Skeletally.
skeleton (n.)
1570s, from Modern Latin sceleton "bones, bony framework of the body," from Greek skeleton soma "dried-up body, mummy, skeleton," from neuter of skeletos "dried-up" (also, as a noun, "dried body, mummy"), from skellein "dry up, make dry, parch," from PIE root *skele- "to parch, wither" (see sclero-).

Skelton was an early variant form. The noun use of Greek skeletos passed into Late Latin (sceletus), hence French squelette and rare English skelet (1560s), Spanish esqueleto, Italian scheletro. The meaning "bare outline" is first recorded c.1600; hence skeleton crew (1778), skeleton key, etc. Phrase skeleton in the closet "source of secret shame to a person or family" is from 1812.
skelm (n.)
also skellum, "a rascal, scamp, scoundrel," 1610s, from Dutch schelm, from German schelm "rascal, devil, pestilence, etc.," from Old High German scelmo. Used by Dryden, but "Now arch. (except in S.Africa)" [OED].

Skeptic does not mean him who doubts, but him who investigates or researches as opposed to him who asserts and thinks that he has found. [Miguel de Unamuno, "Essays and Soliloquies," 1924]
The extended sense of "one with a doubting attitude" first recorded 1610s. The sk- spelling is an early 17c. Greek revival and is preferred in U.S. As a verb, scepticize (1690s) failed to catch on.

"rough drawing intended to serve as the basis for a finished picture," 1660s, from Dutch schets or Low German skizze, both apparently 17c. artists' borrowings from Italian schizzo "sketch, drawing," which is commonly said to be from Latin *schedius (OED compares schedia "raft," schedium "an extemporaneous poem"), from or related to Greek skhedios "temporary, extemporaneous, done or made off-hand," related to skhema "form, shape, appearance" (see scheme (n.)). But according to Barnhart Italian schizzo is a special use of schizzo "a splash, squirt," from schizzare "to splash or squirt," of uncertain origin.

Extended sense of "brief account" is from 1660s; meaning "short play or performance, usually comic" is from 1789. Sketch-book recorded from 1820. German Skizze, French esquisse, Spanish esquicio are likewise from Italian schizzo.

skew (v.)
late 15c., "to turn aside" (intransitive), from Old North French eskiuer "shy away from, avoid," Old French eschiver (see eschew). Transitive sense of "turn (something) aside" is from 1570s. Meaning "depict unfairly" first recorded 1872, on notion of being "give oblique direction to," hence "to distort, to make slant." Statistical sense dates from 1929. Related: Skewed; skewing.

1650s, "having white and brown (or some other color) patches, spotted in an irregular manner" (used especially of horses), from skued "skewbald" (mid-15c.), of unknown origin, + bald "having white patches" (see bald). First element said to be unconnected with skew (v.) (but Klein's sources say it is); OED suggests perhaps from Old French escu "shield," but also notes a close resemblance in form and sense with Icelandic skjottr, "the history of which is equally obscure." Watkins says it is Scandinavian and akin to Old Norse sky "cloud" on the resemblance of the markings to cloud cover.
When the white is mixed with black it is called 'pie-bald,' with bay the name of 'skew-bald' is given to it. ["Youatt's 'The Horse,' " 1866]
As a noun meaning "skewbald horse" from 1863.
skewer (n.)
1670s, variant of dialectal skiver (1660s), perhaps from a Scandinavian source such as Old Norse skifa "a cut, slice" (of bread, etc.), Swedish skifer "a slate," which are related to shiver (n.1) "small piece."

As "a sliding along" from 1890; specifically of motor vehicles from 1903. Skid-mark is from 1914.

In the timber regions of the American West, skids laid down one after another to form a road were "a poor thing for pleasure walks, but admirably adapted for hauling logs on the ground with a minimum of friction" ["Out West" magazine, October 1903]. A skid as something used to facilitate downhill motion led to figurative phrases such as hit the skids "go into rapid decline" (1909), and see skid row.
skid (v.)
1670s, "apply a skid to (a wheel, to keep it from turning)," from skid (n.). Meaning "slide along" first recorded 1838; extended sense of "slip sideways" (on a wet road, etc.) first recorded 1884.

skidoo (v.)
a vogue word of 1905, "to leave in a hurry," perhaps a variant of skedaddle (q.v.). The association with twenty-three is as old as the word, but the exact connection is obscure.

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]
skill (n.)
late 12c., "power of discernment," from Old Norse skil "distinction, ability to make out, discernment, adjustment," related to skilja (v.)
