Etymology

addition = add<to join> + ition<noun suffix>

  • add: From Latin addere ("to add, join"), combining ad- ("to") + dare ("to give").
  • ition: A noun-forming suffix from Latin -itio, indicating an action or process.

Etymology Origin:
The word addition traces back to Latin additio, derived from addere ("to add"). The root add- reflects the act of joining or combining, while -ition transforms it into a noun denoting the process or result. This logical progression—from the verb "to add" to the noun "addition"—mirrors its mathematical and general usage, where it signifies combining elements into a whole.
