Catch caught on river, suitable for catching (7)
I believe the answer is:
capture
'catching' is the definition.
(thesaurus)
'catch caught on river suitable' is the wordplay.
I cannot really understand how this works, but
'caught' could be 'c' (cricket abbreviation) and 'c' is found within the answer.
'on' could be 're' (regarding) and 're' is found within the answer.
'suitable' could be 'apt' (apt means appropriate or fitting) and 'apt' is found within the answer.
A single letter 'u' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for capture that I've seen before include "Ensnare" , "Collar" , "Take by force" , "Take (eg, chess piece)" , "Take on board" .)
