Root Explanation

Blunderer → The word is formed from 'blunder' (of uncertain origin, possibly from Middle English 'blunderen', meaning to stumble or make a mistake) and the suffix '-er' (meaning a person who). A blunderer is a person who makes mistakes or stumbles in their actions.

Memory Tip

Think of someone who 'stumbles' or makes mistakes — that's what a blunderer does, and the '-er' just means a person.
