items

I'm a little stuck... Click here to teach me more about this clue!

'things' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for items that I've seen before include "partners" , "Smite (anag)" , "Individual units" , "Things listed" , "Articles or units on a list" .)

I've seen this clue in the Evening Standard.
