Need coat repaired -- there's yarn (8)
I believe the answer is:
anecdote
'yarn' is the definition.
(I've seen this in another clue)
'need coat repaired' is the wordplay.
'repaired' indicates an anagram.
'need'+'coat'='needcoat'
'needcoat' is an anagram of 'ANECDOTE'.
'there's' is the link.
(Other definitions for anecdote that I've seen before include "Brief tale" , "Reminiscence, story" , "A short amusing story, probably true" , "Short narration" , "Account regarded as unreliable" .)
