'immiscible' originates from Latin, specifically the word 'immiscibilis,' where 'in-' meant 'not' and 'miscibilis' meant 'able to be mixed.'

'immiscibilis' transformed into the French word 'immiscible,' and eventually became the modern English word 'immiscible.'

Initially, it meant 'not able to be mixed,' and this meaning has largely remained the same in modern usage.
