The scoutmaster’s assistant? (4,2,4)
I believe the answer is:
aide de camp
This might be a double definition.
'the scoutmaster's' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'assistant?' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for aide de camp that I've seen before include "Personal assistant" , "Confidentially, one helps" , "military official" , "See military officer" , "Forces PA" .)
