Edited by Aimie Carlson || By Harlon Moss || Published on January 28, 2024
Add is a verb meaning to join or combine, while addition is a noun referring to the act of adding or the thing added.

Key Differences

Add and addition are connected through their root meanings but differ in grammatical usage. Add functions as a verb, implying the action of combining or joining things together. Addition, on the other hand, is a noun, denoting the result of adding or the process itself.
In context, add is used to describe the act of including something, as in arithmetic or in a broader context. Addition is the outcome of this action or the element that has been included. For example, adding numbers results in an addition.
Add is an action, while addition often refers to a supplementary component. In construction, an addition is an extra part added to a building. In mathematics, an addition is the sum.
Add requires a direct object, something to add to. Addition can stand alone or with modifiers, describing what has been added or the act of adding itself.
Usage in a sentence differentiates them further. To add spice to a dish versus the addition of a new room to a house shows their distinct roles as a verb and a noun, respectively.
