crestfallen

The word "crestfallen" is a vivid metaphorical compound from the late 16th century, originally describing a fighting cock whose comb (crest) has drooped after being defeated in battle. The literal image is of a bird's crest or a knight's helmet plume being lowered or fallen from its upright, proud position. This concrete visual of a defeated combatant's slumped posture evolved logically into the modern abstract sense of dejection and dispiritedness following a failure or disappointment. It perfectly encapsulates the physical manifestation of lost pride.

Structure: crest (top) + fallen (dropped) crest: From Old French creste, from Latin crista (tuft, plume, crest). In this compound, it functions as a noun meaning "the top or highest point," often of a helmet or a bird's head. fallen: From Old English feallan (to fall). In this compound, it functions as a past participle adjective meaning "having dropped or been brought down."
