Correspondent, he follows directions (7)
I believe the answer is:
newsman
This could be a double definition.
'correspondent' is the first definition.
(thesaurus)
'he follows directions' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
Can you help me to learn more?
(Other definitions for newsman that I've seen before include "Reporter" , "who sells rags" , "he reports" , "Press person" , "Journalist" .)
