Voice, for example (3)
I believe the answer is:
say
I believe this clue is a double definition.
'voice' is the first definition.
(thesaurus)
'for example' is the second definition.
('say' can be used to introduce an example)
(Other definitions for say that I've seen before include "Utter; e.g." , "Chance to speak" , "Utter; for example" , "SECOND PART OF 24" , "Tell" .)
