How to capture a wayward parent (6)
I believe the answer is:
entrap
'how to capture' is the definition.
(I know that entrap is a kind of capture)
'a wayward parent' is the wordplay.
'a wayward' indicates anagramming the letters (wayward means out of control or chaotic).
'parent' with letters rearranged gives 'ENTRAP'.
(Other definitions for entrap that I've seen before include "decoy" , "Something to do with gin" , "Set up" , "Trick or beguile for parent" , "Catch like parent" .)
