Etymology 1

The verb is derived from Middle English skeuen, skewe, skewen (“to run at an angle or obliquely; to escape”), from Old Northern French escuer [and other forms], variants of Old French eschuer, eschever, eschiver (“to escape, flee; to avoid”) (modern French esquiver (“to dodge (a blow), duck; to elude, evade; to slip away; to sidestep”)), from Frankish *skiuhan (“to dread; to avoid, shun”), from Proto-Germanic *skiuhijan? (“to frighten”). The English word is cognate with Danish skæv (“crooked, slanting; skew, wry”), Norwegian skjev (“crooked, lopsided; oblique, slanting; distorted”), Saterland Frisian skeeuw (“aslant, slanting; oblique; awry”), and is a doublet of eschew.

The adjective and adverb are probably derived from the verb and/or from askew, and the noun is derived from either the adjective or the verb.

2. (transitive) To bias or distort in a particular direction.

5. (intransitive) To jump back or sideways in fear or surprise; to shy, as a horse.
