Word Origin
C14: from Old Norman French escuer to shun, of Germanic origin; compare Middle Dutch schuwen to avoid
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. The adjectival meaning "slanting, turned to one side" is recorded from c.1600, from the verb; noun meaning "slant, deviation" first attested 1680s.
(sky) A transformation of coordinates in which one coordinate is displaced in one direction in proportion to its distance from a coordinate plane or axis. A rectangle, for example, that undergoes skew is transformed into a parallelogram. Also called shear.
