Catch parent out (6)
I believe the answer is:
entrap
'catch' is the definition.
(to entrap is to catch with a trap)
'parent out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'parent' with letters rearranged gives 'ENTRAP'.
(Other definitions for entrap that I've seen before include "Lure into wrongdoing in order to arrest" , "Ensnare, catch" , "Parent (anag)" , "Trick or beguile for parent" , "Take" .)
