Tells, once more, confused tales (7)
I believe the answer is:
relates
'tells' is the definition.
(relating is a kind of telling)
'once more confused tales' is the wordplay.
'once more' becomes 're' (prefix in words like 're-emerge' or 're-enter').
'confused' is an anagram indicator.
'tales' is an anagram of 'lates'.
're'+'lates'='RELATES'
(Other definitions for relates that I've seen before include "Describes" , "couples" , "Narrates" , "Tells (a tale)" .)
