Hard — of hearing? (6)
I believe this is a double definition.
'hard' is the first definition.
(similar in meaning)
'hearing?' is the second definition.
('try' can be a synonym of 'hear')
'of' is the link.
(Other definitions for trying that I've seen before include "Taxing" , "Annoying; sampling" , "Vexatious - having a go" , "Hearing (a case)" , "occupation of Oliver Wendell Holmes Jnr" .)
