Root Explanation

Unintentional → It is formed from "un-" (meaning not) and "intentional" (from Latin "intentio", meaning intention or purpose). The word "unintentional" means not done on purpose or without intention.

Memory Tip

Think of 'not' ('un-') doing something with 'intention' — that's why unintentional means something that happens without purpose.
