Parent dismantled snare (6)
I believe the answer is:
entrap
'snare' is the definition.
(synonyms)
'parent dismantled' is the wordplay.
'dismantled' indicates anagramming the letters.
'parent' with letters rearranged gives 'ENTRAP'.
(Other definitions for entrap that I've seen before include "Catch in a snare" , "Trepan (anag.)" , "Frame -- stitch up" , "Parent (anag)" , "Catch - frame" .)
