Catches parents out (7)
I believe the answer is:
entraps
'catches' is the definition.
(entrapping is a kind of catching)
'parents out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'parents' is an anagram of 'ENTRAPS'.
(Other definitions for entraps that I've seen before include "Takes" , "nets" , "Catches" , "frames" .)
