Mention some organic items (4)
I believe the answer is:
cite
'mention' is the definition.
('cite' can be a synonym of 'mention')
'some organic items' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'CITE' can be found hidden inside 'organic items'.
(Other definitions for cite that I've seen before include "Mention as example or quote" , "Quote (an author)" , "Make reference to" , "Quote or refer to" , "Summon - quote" .)
