Root Explanation

Unsuccessful → It is formed from "un-" (meaning not) and "success" (from Latin "successus", meaning to come close or to achieve). The word "unsuccessful" means not achieving a desired outcome or goal.

Memory Tip

Think of 'not' ('un-') achieving something ('success') — that's why unsuccessful means failing to achieve.
