A mixture of sad and humane but not embarrassed (9)
I believe the answer is:
unashamed
'not embarrassed' is the definition.
(I've seen this before)
'a mixture of sad and humane' is the wordplay.
'a mixture of' is an anagram indicator (letters mixed up).
'and' says to put letters next to each other.
'sad'+'humane'='sadhumane'
'sadhumane' with letters rearranged gives 'UNASHAMED'.
'but' acts as a link.
(Other definitions for unashamed that I've seen before include "Showing no embarrassment" , "Not at all abashed or penitent" , "Without guilt or embarrassment" , "Brazen" , "Impenitent" .)
