Philosopher not working in unit of US soldiers (5)
I believe the answer is:
plato
This clue might be a double definition.
'philosopher' is the first definition.
(Plato is an example)
'working in unit of us soldiers' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'not' acts as a link.
Can you help me to learn more?
(Other definitions for plato that I've seen before include "Teacher of Aristotle, pupil of Socrates" , "Greek philosopher (The Republic)" , "A plot (anag) (known to Aristotle?)" , "Ancient Greek philosopher" , "To pal up with Greek philosopher" .)
