Self-willed boss, wrong to see wife as saint? (10)
I believe the answer is:
headstrong
'self-willed' is the definition.
(I know that self-willed can be written as headstrong)
'boss wrong to see wife as saint?' is the wordplay.
I cannot quite see how this works, but
'boss' could be 'head' (synonyms) and 'head' is found within the answer.
'saint?' could be 'st' (abbreviation) and 'st' is found within the answer.
The remaining letters 'rong' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
(Other definitions for headstrong that I've seen before include "Wilful, determined" , "Showing wilfulness" , "pig-headed" , "obstinately self-willed" , "strong-willed" .)
