His lady is sweet and has taste (6)
I believe the answer is:
sultan
'his lady is sweet and has taste' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
This is the entire clue.
Can you help me to learn more?
(Other definitions for sultan that I've seen before include "Chicken" , "One governs" , "Turkish ruler" , "Ruler of Brunei" , "Muslim ruler" .)
