Synonyms & Antonyms

Root Explanation

Unpin → It is formed from "un-" (meaning not or opposite of) and "pin" (from Old English "pinn", meaning a small pointed object used for fastening). The word "unpin" means to remove or release something that has been fastened with a pin.

Memory Tip

Think of 'un-' meaning not or opposite, and 'pin' as something that fastens. So, unpin means to take away the fastening.
