Superhero grabs wheel in transporter (7)
I believe the answer is:
'transporter' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'superhero grabs wheel' is the wordplay.
'superhero' becomes 'Batman' (DC superhero).
'grabs' indicates putting letters inside.
'wheel' becomes 'o' (I can't explain this - if you can you should believe this answer much more).
'batman' enclosing 'o' is 'BOATMAN'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for boatman that I've seen before include "Water transport provider" , "One having row with" , "Fellow with craft" , "One in charge of a small vessel" , "Sailor" .)
