They are told with least modification (5)
I believe the answer is:
tales
'they are told' is the definition.
The definition suggests an adverb but the answer is not.
'least modification' is the wordplay.
'modification' is an anagram indicator.
'least' is an anagram of 'TALES'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for tales that I've seen before include "Relations" , "provided for defective juries" , "accounts" , "Stories, perhaps tall ones" , "reports" .)
