Couple’s time out (4)
I believe the answer is:
item
'couple's' is the definition.
(I've seen this before)
'time out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'time' is an anagram of 'ITEM'.
(Other definitions for item that I've seen before include "Whole individual unit" , "Component" , "Unit; detail" , "Feature" , "section of magazine" .)
