Root Explanation

Impeccable → It is formed from "in-" (meaning not) and "peccare" (meaning to sin or do wrong). The word "impeccable" means not capable of sinning or being wrong, thus describing something flawless or perfect.

Memory Tip

Think of 'not' ('in-') being combined with 'to sin' ('peccare') — this helps you remember that something impeccable is free from flaws or mistakes.
