Past tense of spill; to accidentally pour or cause liquid to flow out of its container.
From Old English 'spillan' meaning to destroy or waste. The sense of pouring out liquid developed by the 1300s, and 'spilt' became an alternate past tense alongside 'spilled'.
English can't decide between 'spilled' and 'spilt'—Americans prefer 'spilled' while British speakers like 'spilt,' and both are correct, which is why English pronunciation is impossible to learn consistently.
