More suitable amount of beer for the wife? (6,4)
I believe the answer is:
better half
'the wife?' is the definition.
(thesaurus)
'more suitable amount of beer' is the wordplay.
'more suitable' becomes 'better'.
'amount of beer' becomes 'half'.
'better'+'half'='BETTER HALF'
'for' is the link.
(Other definitions for better half that I've seen before include "partner" , "Husband" , "Wife (colloq.)" , "Spouse (informal)" , "One's spouse" .)
