bewilderment

Fernald has no entry of its own for bewilderment; he lists it under amazement, perplexity.

Where he writes about it:

Amazement has in it something of confusion or bewilderment; but confusion and bewilderment may occur without amazement, as when a multitude of details require instant attention. — from amazement

Astonishment may be without bewilderment or confusion. — from amazement

Perplexity (L. per, through, and plecto, plait) is the drawing or turning of the thoughts or faculties by turns in different directions or toward contrasted or contradictory conclusions; confusion (L. confusus, from confundo, pour together) is a state in which the mental faculties are, as it were, thrown into chaos, so that the clear and distinct action of the different powers, as of perception, memory, reason, and will is lost; bewilderment is akin to confusion, but is less overwhelming, and more readily recovered from; perplexity, accordingly, has not the unsettling of the faculties implied in confusion, nor the overwhelming of the faculties implied in amazement or astonishment; it is not the magnitude of the things to be known, but the want of full and definite knowledge, that causes perplexity. — from perplexity

The dividing of a woodland path may cause the traveler the greatest perplexity, which may become bewilderment when he has tried one path after another and lost his bearings completely. — from perplexity

With an excitable person bewilderment may deepen into confusion that will make him unable to think clearly or even to see or hear distinctly. — from perplexity

Astonishment often produces bewilderment, which the word was formerly understood to imply. — from perplexity
