Settled direction of singer (5)
I believe the answer is:
tenor
This could be a double definition.
'settled direction' is the first definition.
'tenor' can be an answer for 'direction' (I've seen this before). I'm not certain of the 'settled' bit.
'singer' is the second definition.
(I know that tenor is a type of singer)
'of' is the link.
Can you help me to learn more?
(Other definitions for tenor that I've seen before include "High male singing voice like Pavarotti" , "Male voice (one of three?)" , "Highest male voice" , "Purport" , "One singing" .)
