Express, for example (3)

I believe the answer is:

say

I believe this is a double definition.

'express' is the first definition.
(saying is a kind of expressing)

'for example' is the second definition.
('say' can be used to introduce an example)

(Other definitions for say that I've seen before include "Opportunity to influence < > state" , "Utter, recite" , "Judge" , "Utter; for example" , "Verbalise" .)

I've seen this clue in The Times.
