Try facial hair, leading to sorrows (10)
I believe the answer is:
heartaches
'sorrows' is the definition.
(I know this)
'try facial hair leading to' is the wordplay.
'try' becomes 'hear' (as in to try someone in court or hear their case).
'facial hair' becomes 'tache' (I've seen this before).
'leading to' becomes 's' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hear'+'tache'+'s'='HEARTACHES'
Can you help me to learn more?
(Another definition for heartaches that I've seen is " Patsy Cline record".)
