Root Explanation

Unthink → It is formed from "un-" (meaning not) and "think" (from Old English "þencan", meaning to conceive in the mind). The word "unthink" means to not conceive or to dismiss a thought from one's mind.

Memory Tip

Think of 'not' ('un-') allowing you to 'conceive' ('þencan') a thought — that's why unthink means to dismiss a thought.
