Spoilt is the British past participle of spoil + -t; spoil derives from Old French espoillier, from Latin spoliare ('to strip, plunder'). The historical chain includes Latin spoliare and Latin spolium. Older glosses in the chain include "to strip, plunder", which help explain the semantic range of the modern word. Morphologically, spoilt is best read as compound, suffixal formation, and borrowing, yielding an English adjective and verb shaped by both form history and later usage. In current English it functions as a adjective and verb, with the sense "ruined, or excessively indulged so as to be selfish (chiefly British)". related forms include spoil, spoiled, and spoilage. The result is an English adjective and verb whose etymology preserves the older forms while supporting the word's specialized modern meaning.
