3. Some pronouns stand for a phrase, a clause, or a sentence, going before or coming after. To be or not to be—that is the question. It is doubtful whether the North Pole will ever be reached. The sails turned, the corn was ground, after which the wind ceased. Ought you to go? I cannot answer that. In the first of these sentences, that stands for a phrase; in the last, for a sentence. It and which in the second and third sentences stand for clauses.
4. Which, retaining its office as connective, may as an adjective accompany its noun; as, I craved his forbearance a little longer, which forbearance he allowed me.]
+A Personal Pronoun is a pronoun that by its form denotes the speaker, the one spoken to, or the one spoken of+.
+A Relative Pronoun is one that relates to some preceding word or words and connects clauses+.
+An Interrogative Pronoun is one with which a question is asked+.
+An Adjective Pronoun is one that performs the offices of both an adjective and a noun+.
The simple personal pronouns are:—I, thou, you, he, she, and it.
The compound personal pronouns are:—Myself, thyself, yourself, himself, herself, and itself.
The simple relative pronouns are:—Who, which, that, and what. [Footnote: As, in such sentences as this: Give such things as you can spare, may be treated as a relative pronoun. But by expanding the sentence as is seen to be a conjunctive adverb—Give such things as those are which you can spare.
But used after a negative is sometimes called a "negative relative" = that not; as, There is not a man here but would die for such a cause. When the sentence is expanded, but is found to be a preposition—There is not a man here but (= except) the one who would die, etc.]
