Scholar raised voice saying 'Sir!' (7)
I believe the answer is:
baronet
'saying sir' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'scholar raised voice' is the wordplay.
'scholar' becomes 'ba'.
'raised' says the letters should be written in reverse (going up in a down clue).
'voice' becomes 'tenor' (one of the voices in a choir say).
'tenor' written backwards gives 'ronet'.
'ba'+'ronet'='BARONET'
Can you help me to learn more?
(Other definitions for baronet that I've seen before include "Hereditary knight" , "Lowest British hereditary title" , "Bent oar (anag.)" , "Sir Somebody-or-other?" , "Lower noble" .)
