Voice, for example (3)
I believe the answer is:
say
This clue is a double definition.
'voice' is the first definition.
(I know that voice is a more specific form of say)
'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" .)
