Unruly, awkward spouse Robert (12)
I believe the answer is:
obstreperous
'unruly' is the definition.
('obstreperous' can be a synonym of 'unruly')
'awkward spouse robert' is the wordplay.
'awkward' is an anagram indicator.
'spouse'+'robert'='spouserobert'
'spouserobert' anagrammed gives 'OBSTREPEROUS'.
(Other definitions for obstreperous that I've seen before include "Noisy, hard to control" , "Disruptive" , "Noisily aggressive" , "Sober posture (anag) - unruly" , "Bolshie" .)
