Respect shown in a testimonial (9)
I believe the answer is:
reference
I believe this clue is a double definition.
'respect' is the first definition.
(thesaurus)
'a testimonial' is the second definition.
(reference is a kind of testimonial)
'shown in' is the link.
(Other definitions for reference that I've seen before include "Direction to source information" , "Citation in a book or article" , "Testimonial - allusion" , "Allusion, mention" , "Formal recommendation to an employer" .)
