Drive off to see sportsman (5)
I believe the answer is:
diver
'sportsman' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'drive off' is the wordplay.
'off' is an anagram indicator.
'drive' anagrammed gives 'DIVER'.
'to see' acts as a link.
Can you help me to learn more?
(Other definitions for diver that I've seen before include "One plunges head first into water" , "One jumping off board" , "Water bird" , "Grebe maybe" , "Frogman" .)
