Word puzzle produced by Socratic lunatic (8)
I believe the answer is:
acrostic
'word puzzle' is the definition.
(I've seen this before)
'socratic lunatic' is the wordplay.
'lunatic' indicates an anagram.
'socratic' is an anagram of 'ACROSTIC'.
'produced by' acts as a link.
(Other definitions for acrostic that I've seen before include "Puzzle involving a hidden message" , "code?" , "Puzzle involving leading characters" , "Word puzzle using initials of lines of poetry" , "Puzzle spelling out something with first letters" .)
