'addability' originates from the English word 'add,' combined with the suffix '-ability,' which denotes the capacity or suitability for a specified action.

'add' changed from the Latin word 'addere,' which transformed into the French word 'ad(d)er,' and eventually became the modern English word 'add.' The suffix '-ability' was added to form 'addability.'

Initially, 'add' meant 'to give or add something,' and this meaning has largely remained the same in modern usage. 'Addability' extends this to the capacity to be added.
