Cast altered and recounted (7)
I believe the answer is:
related
'recounted' is the definition.
(relating is a kind of recounting)
'cast altered' is the wordplay.
'cast' indicates an anagram.
'altered' with letters rearranged gives 'RELATED'.
'and' acts as a link.
(Other definitions for related that I've seen before include "Told; akin" , "Family members must be" , "Connected by family ties" , "Connected by blood or marriage" , "Told (a story etc)" .)
