EXCLAMATIONS
Appropriate intonation can be imposed on any type of unit, including a single word, to express an exclamation (Splendid! Gotcha!). [AmE]
With appropriate intonation, all the clause types can be used to make exclamations: the exclamative structure 1, 2; an interrogative 3, 4; a declarative 5, 6; an imperative 7; a verbless clause 8, 9; a nominal group 10:
Interrogative exclamations, unlike basic exclamatives, call for agreement or disagreement from the hearer: A. Isn’t it a lovely day! B. Yes, it is.
Such, so and other intensifying items such as terribly also confer exclamative force on a declarative:
He’s such a bore! It’s so tiring!
It’s terribly hot! It was extraordinarily beautiful!
