'fumigate' originates from Latin, specifically the word 'fumigare,' where 'fumus' meant 'smoke.'

'fumigare' transformed into the French word 'fumiguer,' and eventually became the modern English word 'fumigate' through Middle English.

Initially, it meant 'to smoke or perfume,' but over time it evolved into its current meaning of 'to disinfect or purify with fumes.'
