Might he cart around an Oscar? (5)
I believe the answer is:
actor
'might he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'cart around an oscar?' is the wordplay.
I cannot quite see how this works, but
'around' could be 'o' (a round letter) and 'o' is present in the answer.
an anagram of 'cart' is 'actr' which is present in the left over letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for actor that I've seen before include "Cruise maybe" , "one to take on roles" , "Dramatic artist" , "Luvvy" , "Stage-player" .)
