An item or two? (4)
I believe the answer is:
pair
I believe this clue is a double definition.
'an item' is the first definition.
(both can mean a romantic couple)
'two?' is the second definition.
(pair is a kind of two)
'or' acts as a link.
(Other definitions for pair that I've seen before include "Duo" , "2" , "how braces come" , "Two ducks in one game of cricket" , "Twosome" .)
