General secretary (4)
I believe the answer is:
aide
This clue could be a double definition.
'general' is the first definition.
(thesaurus)
'secretary' is the second definition.
The definition and answer 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 aide that I've seen before include "Idea (anag)" , "auxiliary" , "Officer's assistant" , "one helping" , "Assistant to a more senior person" .)
