Does she not strike us as being wifely? (6)
I believe the answer is:
missus
'does she' is the definition.
The definition suggests a singular noun which matches the answer.
'not strike us as being wifely?' is the wordplay.
I cannot really understand how this works, but
'us' is present in the answer.
'being' could be 'miss' (miss is a kind of being) and 'miss' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for missus that I've seen before include "Wife (informal)" , "As partner" , "Wife (colloquial)" , "trouble and strife" , "Dutch American" .)
