'emulsify' originates from Latin, specifically the word 'emulsus,' where 'e-' meant 'out' and 'mulsus' meant 'to milk.'

'emulsus' transformed into the French word 'émulsifier,' and eventually became the modern English word 'emulsify.'

Initially, it meant 'to milk out,' but over time it evolved into its current meaning of 'to mix two liquids to form an emulsion.'
