  • The imperative Drink! cannot be challenged by the question 'is it true or not?' which may be, however, perfectly well asked after such sentences as 'one drank', 'one will drink', 'one would drink'. (Jakobson, 1960, p. 355) Considering that declarative sentences clearly activate the referential function, then the truth value test becomes a test we can use to identify the referential function.
