Wife suffering is rolling round (9)
I believe the answer is:
wallowing
'rolling round' is the definition.
The answer and definition can be both to do with motion as well as being present participle verbs.
Perhaps they are linked in a way I don't understand?
'wife suffering' is the wordplay.
'wife' becomes 'w' (abbreviation).
'suffering' becomes 'allowing' (suffer can mean to allow or tolerate).
'w'+'allowing'='WALLOWING'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for wallowing that I've seen before include "rolling about in mud" , "Indulging oneself" .)
