Getting involved, with no time for water sport (7)
I believe the answer is:
angling
'sport' is the definition.
(angling is a kind of sport)
'getting involved with no time for water' is the wordplay.
I cannot really see how this works, but
'involved' could be 'in' (to be involved in something is to be 'in' it) and 'in' is present in the answer.
'no' could be 'n' (common abbreviation) and 'n' is found within 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 "seeking compliments, perhaps?" , "Pursuit with hook, line and sinker?" , "Walton practised it" , "Pointing" , "Fishing with rod and line" .)
