Root Explanation

Irrefutably → It is formed from "in-" (meaning not), "refutare" (meaning to disprove or rebut), and "-ably" (meaning in a manner). The word means in a manner that cannot be disproven or rebutted.

Memory Tip

Think of something that cannot be 'disproved' ('refutare') — the 'in-' means not, and '-ably' indicates the manner. This helps you remember that 'irrefutably' means something that cannot be disproven.
