Couple a little bit emotional (4)
I believe the answer is:
item
'couple' is the definition.
(I've seen this before)
'a little bit emotional' is the wordplay.
'a little' says the answer is hidden in the clue.
'ITEM' is hidden in the letters of 'bit emotional'.
(Other definitions for item that I've seen before include "One thing - two people, perhaps" , "One of a series (or a couple!)" , "Two people romantically linked" , "Two people considered together (informal)" , "Bit of information" .)
