Root Explanation

Confirmatory → It is formed from "con-" (meaning together) and "firmare" (meaning to make firm or strengthen) and the suffix "-ory" (meaning relating to). The word "confirmatory" refers to something that relates to making something firm or strengthening a belief or statement.

Memory Tip

Think of 'together' ('con-') making something 'firm' ('firmare') — that's why confirmatory means relating to strengthening a belief or statement.
