General drift of singer (5)
I believe the answer is:
tenor
I believe this is a double definition.
'general drift' is the first definition.
(I've seen this in another clue)
'singer' is the second definition.
(I know that tenor is a type of singer)
'of' acts as a link.
(Other definitions for tenor that I've seen before include "Eg, Caruso" , "Placido Domingo, say" , "Highest male voice" , "Meaning - male singing voice" , "Male singing voice of high pitch" .)
