Principals prohibit learning about teachings of this idealist (5)
I believe the answer is:
plato
'idealist' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'principals prohibit learning about teachings of' is the wordplay.
'principals' indicates taking the first letters (I've seen 'principal of' mean this).
'of' becomes 'o''.
The initial letters of 'prohibit learning about teachings' is 'plat'.
'plat'+'o'='PLATO'
'this' acts as a link.
Can you help me to learn more?
(Other definitions for plato that I've seen before include "Moon crater named after Greek philosopher" , "Ancient Greek philosopher" , "Ancient Athenian philosopher, pupil of Socrates" , "Republican writer?" , "Teacher of Aristotle, pupil of Socrates" .)
