One might fly US pro here to play (9)
I believe the answer is:
superhero
'one might fly' is the definition.
The definition suggests a singular noun which matches the answer.
'us pro here to play' is the wordplay.
'to play' indicates anagramming the letters.
'us'+'pro'+'here'='usprohere'
'usprohere' anagrammed gives 'SUPERHERO'.
Can you help me to learn more?
(Other definitions for superhero that I've seen before include "One possibly involved in saving" , "person who catches lots of baddies" , "Batman, say?" , "Fictional character with strange powers" , "comic book creation" .)
