'excrement' originates from Latin, specifically the word 'excrementum,' where 'ex-' meant 'out of' and 'crescere' meant 'to grow.'

'excrementum' transformed into the Old French word 'excrement,' and eventually became the modern English word 'excrement' through Middle English.

Initially, it meant 'something that grows out,' but over time it evolved into its current meaning of 'waste matter discharged from the bowels.'
