Akin, so it is told (7)
I believe the answer is:
related
I believe this is a double definition.
'akin' is the first definition.
(similar in meaning)
'it is told' is the second definition.
(as in relating a story)
'so' is the link.
(Other definitions for related that I've seen before include "As siblings obviously are" , "Connected by blood or marriage" , "Kin; connected" , "Told (a story etc)" , "Father and son have to be" .)
