Tale of a holy man or youth leader (5)
I believe the answer is:
story
'tale' is the definition.
(I know that tale can be written as story)
'a holy man or youth leader' is the wordplay.
'a holy man' becomes 'st' (abbreviation for saint).
'youth leader' becomes 'y' (I've seen this in other clues).
'st'+'or'+'y'='STORY'
'of' acts as a link.
(Other definitions for story that I've seen before include "Account, tale" , "Narrative or account" , "Narration" , "Rumour" , "Tale - lie" .)
