Hear song of praise for that man (3)
I believe the answer is:
him
'that man' is the definition.
(him refers to a man)
'hear song of praise' is the wordplay.
'hear' shows a homophone (sound like).
'song of praise' becomes 'hymn' (I've seen this before).
'hymn' sounds like 'HIM'.
'for' acts as a link.
(Other definitions for him that I've seen before include "Objective male pronoun" , "That man" , "Proper character" .)
