Philosopher who gets on with soldiers (5)
I believe the answer is:
plato
'philosopher who gets on with soldiers' is the definition.
'Plato' can be an answer for 'philosopher' (Plato is an example). I'm not sure about the remainder of the definition.
'philosopher who gets on' is the wordplay.
'philosopher who' becomes 'plo' (I am not sure about this - if you are sure you should believe this answer much more).
'gets' is an insertion indicator (gets can mean captures or absorbs).
'on' becomes 'at' (I've seen this in other clues).
'plo' going around 'at' is 'PLATO'.
Can you help me to learn more?
(Other definitions for plato that I've seen before include "Philosopher of ancient Greece" , "Republic author" , "Ancient Greek philosopher" , "Greek philosopher, disciple of Aristotle" , "Greek character" .)
