Society yet troubled by inflammation (4)
I believe the answer is:
stye
'inflammation' is the definition.
(I've seen this before)
'society yet troubled by' is the wordplay.
'society' becomes 's' (common abbreviation in names of organisations).
'troubled' indicates an anagram.
'by' says to put letters next to each other.
'yet' anagrammed gives 'tye'.
's'+'tye'='STYE'
(Other definitions for stye that I've seen before include "Eyelid problem" , "Eye sore" , "nasty spot" , "It pains viewer" , "Viewer's complaint" .)
