Origin
From Middle English eschewen, from Anglo-Norman eschiver (third-person present eschiu), from Frankish *sciuhan ("to dread, shun, avoid"), from Proto-Germanic *skiuhwijanÄ… ("to frighten"). Cognate with Old High German sciuhen ("to frighten off"). More at shy.

The verb eschew is not normally applied to the avoidance or shunning of a person or physical object, but rather, only to the avoidance or shunning of an idea, concept, or other intangible.
