Confused, perplexed surprise.
Confused, perplexed surprise — being lost and unable to make sense of what one faces.
The confused, can't-make-sense-of-it variety of surprise: the mind is active but failing to orient. Unlike shock it carries no jolt or trauma; unlike dismay no discouragement; unlike stupefaction no mental shutdown — just disorientation. Its literal image is being led astray into trackless wild country. Mildly unpleasant rather than distressing.
From bewilder (1680s), be- “thoroughly” + archaic wilder “lead astray, lure into the wilds” (probably a back-formation from wilderness). The literal image is being lost in trackless country.
The verb began both literally (“confuse as to direction,” 1680s) and figuratively (“perplex”); the noun (1789) first meant the state, then also a confusing tangle (1840). Stable in meaning since the 19th century. No reliable recent-generation shift.
