IPA: /ˈrɒŋˌhɛdɪd/
KK: /ˈrɔŋˌhɛdɪd/
Having a stubborn or misguided opinion that is not based on good judgment.
His wrongheaded approach to solving the problem only made things worse.
Wrongheaded → It is formed from "wrong" (from Old English *wrang*, meaning incorrect or unjust) and "headed" (from "head", meaning the leader or person in charge). The word "wrongheaded" describes someone who is misguided or has a faulty way of thinking, as if their head is leading them in the wrong direction.
Think of someone whose thoughts are 'incorrect' ('wrong') and who is being led by their 'head' — that's why wrongheaded means having misguided ideas.
