Right heading (5)
I believe the answer is:
title
I believe this is a double definition.
'right' is the first definition.
(title is a kind of right)
'heading' is the second definition.
(title is a kind of heading)
(Other definitions for title that I've seen before include "Form of address - name" , "Caption; name" , "'The name of a book, say (5)'" , "confers ownership" , "Chapter heading" .)
