Last of many to raise voice (4)
I believe the answer is:
alto
'voice' is the definition.
(alto is a kind of voice)
'last of many to raise' is the wordplay.
I cannot really see how this works, but
'last' could be 't' (I've seen this in other clues) and 't' is present in the answer.
'of' could be 'o' and 'o' is found within the answer.
'many' could be 'l' and 'l' is found within the answer.
A single letter 'a' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for alto that I've seen before include "Highest male voice: lowest female voice" , "someone to sing" , "Singing range" , "Singing voice between tenor and soprano" , "Kind of singing voice, male or female" .)
