Part of school I arrange for storyteller (4)
I believe the answer is:
liar
'storyteller' is the definition.
(I've seen this before)
'part of school i arrange' is the wordplay.
'part of' indicates a hidden word.
'LIAR' is hidden in the letters of 'school i arrange'.
'for' acts as a link.
(Other definitions for liar that I've seen before include "One not telling the truth" , "Not a truth-sayer!" , "Teller of untruths" , "Teller of fibs" , "Perjurer" .)
