The word 'spoils' originates from the Latin spolium, which initially referred to the hide or skin stripped from an animal. This concrete act of stripping was metaphorically extended to mean the arms stripped from a defeated enemy, thus becoming 'booty' or 'plunder.' Entering English via Old French espoille, the core verb 'spoil' retained these twin concepts: the act of plundering (seizing goods) and the resultant state of being stripped of value (ruination). The modern noun 'spoils,' specifically meaning the profits of victory, directly preserves the ancient Roman concept of war booty, while its verbal use for ruining something reflects the logical extension of stripping something of its worth or original condition.

Structure: spoil (to plunder, to decay) + s (plural/verb suffix) spoil: From Latin spoliare (to plunder, strip), from spolium (skin, hide; arms stripped from a foe, booty). In this word, it functions as the core root carrying the dual historical senses of "plunder" and "to strip of value." s: A native English inflectional suffix, from Proto-Germanic, indicating either plural number for nouns or third person singular present tense for verbs.
