Snare fish after net's repaired (8)
I believe the answer is:
entangle
'snare' is the definition.
(thesaurus)
'fish after net's repaired' is the wordplay.
'fish' becomes 'angle' (angling is a kind of fishing**).
'after' means one lot of letters go next to another.
'repaired' indicates an anagram.
'net' with letters rearranged gives 'ent'.
'angle' put after 'ent' is 'ENTANGLE'.
(Other definitions for entangle that I've seen before include "Involve in complicated circumstances" , "Create confusion" , "Snare" , "Ensnare" , "caught up" .)
