One acted out story (8)
I believe the answer is:
anecdote
'story' is the definition.
(an amusing or interesting story)
'one acted out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'one'+'acted'='oneacted'
'oneacted' with letters rearranged gives 'ANECDOTE'.
(Other definitions for anecdote that I've seen before include "One acted (anag) - amusing reminiscence" , "Date once (anag.)" , "Humorous story" , "Short enteryaining tale" , "Short account of an incident" .)
