Given the right to secure championship in final (8)
I believe the answer is:
entitled
'given the right' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'championship in final' is the wordplay.
'championship' becomes 'title' (a championship is a sporting title).
'in' is an insertion indicator.
'final' becomes 'end' (synonyms).
'title' inserted into 'end' is 'ENTITLED'.
'to secure' is the link.
Can you help me to learn more?
(Other definitions for entitled that I've seen before include "Authorized" , "Given right - named" , "Gave a right to, or named a book" , "Named; allowed" , "Authorised; bearing the name" .)
