Not all exclamatory words are interjections.
Other interjections are oh! ah! alas! pshaw! hurrah! etc. But it is to be remembered that almost any word may be used as an exclamation, but it still retains its identity as noun, pronoun, verb, etc.: for example, "Books! lighthouses built on the sea of time [noun];" "Halt! the dust-brown ranks stood fast [verb]," "Up! for shame! [adverb]," "Impossible! it cannot be [adjective]."

ANALYSIS OF SENTENCES.
CLASSIFICATION ACCORDING TO FORM.
What analysis is..
335. All discourse is made up of sentences: consequently the sentence is the unit with which we must begin. And in order to get a clear and practical idea of the structure of sentences, it is necessary to become expert in analysis; that is, in separating them into their component parts.
A general idea of analysis was needed in our study of the parts of speech,—in determining case, subject and predicate, clauses introduced by conjunctions, etc.
Value of analysis.
