She'll never strike us as "the better half" (6)
I believe the answer is:
missus
'the better half' is the definition.
(I've seen this in another clue)
'she'll never strike us' is the wordplay.
I cannot really understand how this works, but
'us' is within the answer.
The remaining letters 'miss' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'as' is the link.
Can you help me to learn more?
(Other definitions for missus that I've seen before include "As partner" , "Wife (informal)" , "trouble and strife" , "The old lady" , "Dutch American" .)
