Cite problem with wife more than once (5)
I believe the answer is:
twice
'more than once' is the definition.
(I've seen this in another clue)
'cite problem with wife' is the wordplay.
'problem with' indicates anagramming the letters.
'wife' becomes 'w' (abbreviation).
'cite' anagrammed with 'w' gives 'TWICE'.
(Other definitions for twice that I've seen before include "Double in quantity" , "Doubly" , "Two times" , "You only live -- (film)" .)
