Root Explanation

Confirmation → It is formed from "con-" (meaning together) and "firmare" (meaning to make firm or strengthen). The word "confirmation" refers to the act of making something firm or certain together with others, often in a formal context.

Memory Tip

Think of coming together ('con-') to make something strong or certain ('firmare') — that's why confirmation means to make something certain.
