'amovable' originates from Latin, specifically the word 'amovibilis', where 'a-' meant 'away' and 'movibilis' meant 'movable'.

'amovibilis' transformed into the Old French word 'amovable', and eventually became the modern English word 'amovable'.

Initially, it meant 'capable of being moved', and this meaning has largely remained the same in modern usage.
