'alluvium' originates from Latin, specifically the word 'alluvius,' where 'ad-' meant 'toward' and 'luere' meant 'to wash.'

'alluvius' transformed into the English word 'alluvium,' and eventually became the modern English word 'alluvium.'

Initially, it meant 'to wash toward,' but over time it evolved into its current meaning of 'a deposit left by flowing water.'
