Address in Portuguese senate hours before (6)
I believe the answer is:
senhor
'address in portuguese' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for senhor that I've seen before include "A Portuguese gentleman or sir" , "gent in Lisbon" , "Herons for a Portuguese gentleman" .)
