the word 'spilled' is the regular past tense and past participle form of the verb 'spill'. the root 'spill' originates from old english spillan, which carried the strong sense of 'to destroy, kill, or waste'. this meaning is preserved in the archaic phrase 'spill blood'. over time, the sense softened and narrowed, focusing specifically on the wasteful or accidental escape of liquids, a concept closely linked to the idea of loss or waste. the '-ed' suffix is the standard germanic marker for past tense, making 'spilled' a straightforward morphological construction where the ancient root's core idea of 'causing something to be lost' logically evolved into its modern, more specific application.

Structure: spill + ed 'spill' (from old english spillan, meaning 'to destroy, kill, waste') is the verb root. '-ed' (from old english -ode, -ade, a past tense and past participle suffix) is an inflectional suffix indicating past action or state.
