Root Explanation

Unthinkingly → It is formed from "un-" (meaning not) and "think" (from Old English "þencan", meaning to conceive in the mind) and "-ingly" (a suffix used to form adverbs). The word describes the act of doing something without thinking or consideration.

Memory Tip

Think of 'not' ('un-') thinking ('think') when you do something without consideration — that's what unthinkingly means.
