Stories least translated (5)
I believe the answer is:
tales
'stories' is the definition.
('tale' can be a synonym of 'story')
'least translated' is the wordplay.
'translated' indicates anagramming the letters.
'least' with letters rearranged gives 'TALES'.
(Other definitions for tales that I've seen before include "Stale kind of stories" , "provided for defective juries" , "accounts" , "Stories, perhaps tall ones" , "Lies" .)
