Spouse detailed to return with catch (6)
I believe the answer is:
entrap
'catch' is the definition.
(to entrap is to catch with a trap)
'spouse detailed to return' is the wordplay.
'spouse' becomes 'partner' (synonyms).
'detailed' means to remove the last letter (the word must be end-less or 'de-tailed').
'to return' shows that the letters should be reversed in order.
'partner' with its final letter taken off is 'partne'.
'partne' written backwards gives 'ENTRAP'.
'with' acts as a link.
(Other definitions for entrap that I've seen before include "Parent (anag)" , "Catch like parent" , "Set up" , "Something to do with gin" , "Take" .)
