Snare fish after net damaged (8)
I believe the answer is:
entangle
'snare' is the definition.
(thesaurus)
'fish after net damaged' is the wordplay.
'fish' becomes 'angle' (angling is a kind of fishing**).
'after' is a charade indicator (letters next to each other).
'damaged' is an anagram indicator.
'net' with letters rearranged gives 'ent'.
'angle' put after 'ent' is 'ENTANGLE'.
(Other definitions for entangle that I've seen before include "Get tied up in knots in neat glen" , "Create confusion" , "Ravel" , "Involve in complicated circumstances" , "catch" .)
