Save Italian number for male singer (8)
I believe the answer is:
baritone
'male singer' is the definition.
(I've seen this before)
'save italian number' is the wordplay.
'save' becomes 'bar' (I've seen this before).
'italian' becomes 'it'.
'number' becomes 'one' (one is a kind of number).
'bar'+'it'+'one'='BARITONE'
'for' acts as a link.
(Other definitions for baritone that I've seen before include "One who can sing" , "Male singer looks odd in boater" , "solo voice" , "Male voice with deep register" , "Second lowest male singing voice" .)
