Note. Thus nonsense! and fire! are nouns in the exclamatory nominative; I! is a pronoun in the same construction; halt! is a verb in the imperative (compare hark! hush! behold! look!); good! is an adjective; forward! on! away! and back! are adverbs; but! is a conjunction.

The following examples illustrate various exclamatory expressions,—words, phrases, and sentences:—

CHAPTER X
CLAUSES AS PARTS OF SPEECH

376. A clause is a group of words that forms part of a sentence and that contains a subject and a predicate.

A clause used as a part of speech is called a subordinate clause ([§ 46]).

377. A subordinate clause may be introduced by (1) a relative or an interrogative pronoun, (2) a relative or an interrogative adverb, (3) a subordinate conjunction.

The relative pronouns are: who, which, what, that (= who or which), as (after such or same), and the compound relatives whoever, whichever, whatever. Their uses have already been studied ([pp. 66–73]).

The chief relative adverbs are: where, whence, whither, wherever, when, whenever, while, before, after, till, until, since, as, how, why ([p. 86]).
