Speak, for example (3)
I believe the answer is:
say
I believe this is a double definition.
'speak' is the first definition.
(I've seen this in other clues)
'for example' is the second definition.
('say' can be used to introduce an example)
(Other definitions for say that I've seen before include "Articulate" , "Tell" , "Pronounce" , "by way of example" , "State; for instance" .)
