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

'amovibilis' transformed into the French word 'amovible', and eventually became the modern English word 'amovable', leading to 'amovability'.

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