Notice we’d gone to get wife? (6)
I believe the answer is:
missus
'wife?' is the definition.
(informal term for someone's wife)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for missus that I've seen before include "The old lady" , "Wife (colloquial)" , "Dutch American" , "Wife (informal)" , "As partner" .)
