Synonyms & Antonyms

Root Explanation

The word 'unpen' is formed from the prefix 'un-' (meaning not) and 'pen' (from Old English 'penna', meaning to confine or enclose). The term 'unpen' means to remove the confinement or enclosure, essentially to free or release something.

Memory Tip

Think of 'un-' meaning not, and 'pen' relating to confinement — so 'unpen' means to not confine, or to free something from being enclosed.
