Particulars of troubled times
I believe the answer is:
items
'particulars' is the definition.
('item' can be a synonym of 'particular')
'troubled times' is the wordplay.
'troubled' indicates an anagram.
'times' is an anagram of 'ITEMS'.
'of' is the link.
(Other definitions for items that I've seen before include "Separate objects or units" , "Couples" , "Individual parts" , "Smite (anag)" , "Elements" .)
