Direct plays with puns ad-libbed (10)
I believe the answer is:
unscripted
'ad-libbed' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can occasionally mean the same thing.
'direct plays with puns' is the wordplay.
'plays with' indicates anagramming the letters.
'direct' anagrammed with 'puns' can make 'UNSCRIPTED'.
Can you help me to learn more?
(Other definitions for unscripted that I've seen before include "Impromptu" , "off the cuff" , "unexpected" .)
