Volunteers terribly maudlin state (5,4)
I believe the answer is:
tamil nadu
'state' is the definition.
(Indian state)
'volunteers terribly maudlin' is the wordplay.
'volunteers' becomes 'TA' (abbreviation for Territorial Army).
'terribly' is an anagram indicator.
'maudlin' with letters rearranged gives 'milnadu'.
'ta'+'milnadu'='TAMIL NADU'
(Other definitions for tamil nadu that I've seen before include "Southern Indian state" , "Southern state of India" , "state bordering Kerala" .)
