Agent of intelligence? (3)
I believe the answer is:
spy
This might be a double definition.
'agent' is the first definition.
(spy is a kind of agent)
'intelligence?' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for spy that I've seen before include "Keep watch secretly, maybe for foreign government" , "Undercover agent" , "Notice" , "Mole, agent" , "One gathers information on enemies" .)
