Suffering, try facial adornment (9)
I believe the answer is:
heartache
'suffering' is the definition.
(I've seen this before)
'try facial adornment' is the wordplay.
'try' becomes 'hear' (as in to try someone in court or hear their case).
'facial adornment' becomes 'tache' (short for moustache).
'hear'+'tache'='HEARTACHE'
(Other definitions for heartache that I've seen before include "Emotional anguish" , "Emotional distress" , "Agony of Love" , "Suffering" , "it gives rise to anguish" .)
