His productions have taste (4)
I believe the answer is:
chef
This could be a double definition.
'his productions' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'have taste' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for chef that I've seen before include "Cooker?" , "One who prepares courses" , "who has a set of knives?" , "Professional cook" , "Kitchen head" .)
