Pronoun

Definition and stakes

Samuel Kirkham,  English Grammar in Familiar Lectures

“ The word pronoun comes from the two Latin words, pro, which means for, or instead of, and nomen, a name, or noun. Hence you perceive, that pronoun means for a noun, or instead of a noun.
In the sentence, "The man is happy; he is benevolent; he is useful;" you perceive, that the word he is used instead of the noun man; consequently he must be a pronoun. You observe, too, that, by making use of the pronoun he in this sentence, we avoid the repetition of the noun man, for without the pronoun, the sentence would be rendered thus, "The man is happy; the man is benevolent; the man is useful."
