'spilt' originates from Old English, specifically the word 'spillan,' where 'spillan' meant 'to destroy or kill.'

'spillan' transformed into the Middle English word 'spillen,' and eventually became the modern English word 'spill.'

Initially, it meant 'to destroy or kill,' but over time it evolved into its current meaning of 'to cause or allow (liquid) to flow over the edge of its container.'
