Individual items (5)
I believe the answer is:
units
'individual items' is the definition.

This is the entire clue.
(Other definitions for units that I've seen before include "Individual things or groups" , "Eg, cm, kg and ft" , "Detachments" , "Individual things, like pieces of furniture" , "Apparatus similar to barbecue" .)
