Region has area for one to entertain (8)
I believe the answer is:
distract
'one to entertain' is the definition.
(thesaurus)
'region has area for' is the wordplay.
'region' becomes 'tract' (both can mean a large piece of land).
'has' is a charade indicator (letters next to each other).
'area for' becomes 'dis' (I can't justify this - if you can you should believe this answer much more).
'tract' put after 'dis' is 'DISTRACT'.
Can you help me to learn more?
(Other definitions for distract that I've seen before include "Draw someone's attention away from something" , "Puzzle" , "Divert (attention) from something" , "amuse" , "Cause to lose concentration" .)
