Socratic form of puzzle (8)
I believe the answer is:
'puzzle' is the definition.
(I've seen this before)
'socratic form' is the wordplay.
'form' indicates an anagram.
'socratic' with letters rearranged gives 'ACROSTIC'.
'of' acts as a link.
(Other definitions for acrostic that I've seen before include "Word puzzle using first letters" , "RAC stoic (anag) - lines of writing where certain initial letters form a word or proverb" , "Initial letter puzzle" , "Socratic sort of word puzzle" , "Form of word puzzle" .)
