Some excitement for couple (4)
I believe the answer is:
item
'couple' is the definition.
(I've seen this before)
'some excitement for' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'ITEM' is hidden within 'excitement for'.
(Other definitions for item that I've seen before include "Indivual unit" , "Individual thing" , "Two people widely seen as one?" , "One thing on a list" , "story" .)
