Making a bid for sport (7)
I believe the answer is:
angling
'for sport' is the definition.
(angling is a kind of sport)
'making a bid' is the wordplay.
I cannot really see how this works, but
'a' could be 'an' and 'an' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for angling that I've seen before include "Indirectly seeking" , "Pointing" , "riverside activity?" , "seeking compliments, perhaps?" , "Pursuit with hook, line and sinker?" .)
