'admixture' originates from Latin, specifically the word 'admixtura,' where 'ad-' meant 'to' and 'mixtura' meant 'a mixing.'

'admixtura' transformed into the Middle English word 'admixtur,' and eventually became the modern English word 'admixture.'

Initially, it meant 'a mixing or mingling,' but over time it evolved into its current meaning of 'a substance added to something else.'
