Divorce? (8)

I believe the answer is:

uncouple

'divorce?' is the definition.
(thesaurus)

This is the entire clue.

(Other definitions for uncouple that I've seen before include "Release" , "Detach (truck from train)" , "Disconnect" , "Detach (a railway carriage)" , "Detach one train carriage from another" .)

I've seen this clue in the Evening Standard and The Irish Independent.
