Give out wrong item (4)
I believe the answer is:
emit
'give out' is the definition.
(synonyms)
'wrong item' is the wordplay.
'wrong' indicates an anagram.
'item' with letters rearranged gives 'EMIT'.
(Other definitions for emit that I've seen before include "Produce and discharge" , "Conductor; telegram (US)" , "Give off or discharge" , "Send out in time" , "Sent" .)
