Account with date once rendered (8)
I believe the answer is:
anecdote
'account' is the definition.
(anecdote is a kind of account)
'with date once rendered' is the wordplay.
'with' means one lot of letters go next to another.
'rendered' indicates anagramming the letters.
'date' next to 'once' is 'dateonce'.
'dateonce' is an anagram of 'ANECDOTE'.
(Other definitions for anecdote that I've seen before include "Short entertaining story" , "One acted (anag) - amusing reminiscence" , "Short and amusing/interesting story" , "Short amusing tale" , "Brief tale" .)
