Etymology
the word 'addition' entered english in the late 14th century from old french adition, which itself originated from latin additionem, the noun of action from addere. the latin verb addere is a compound of ad- (meaning 'to') and dare (meaning 'to give'), thus literally conveying the sense 'to give to'. this core idea of joining one thing to another evolved from the physical act of giving or attaching into the abstract mathematical operation and the general concept of including something extra. the suffix -ition solidifies the action or its result into a state or process, forming the modern noun.
