Frank Edgar Farley,  An Advanced English Grammar with Exercises

“ A compound subject or predicate consists of two or more simple subjects or predicates, joined, when necessary, by conjunctions.
Either the subject or the predicate, or both, may be compound.
The Parts of Speech
9. In accordance with their use in the sentence, words are divided into eight classes called parts of speech,—namely, nouns, pronouns, adjectives, verbs, adverbs, prepositions, conjunctions, and interjections.
(1) A noun is the name of a person, place, or thing.
(2) A pronoun is a word used instead of a noun. It designates a person, place, or thing without naming it.

William Stevens Balch,  Lectures on Language, as Particularly Connected with English Grammar

“ At the same time, it is necessary to set proper bounds to this business, so as not to occasion obscurity and perplexity, when we mean to be simple and perspicuous. Instead, therefore, of making a separate mood for every auxiliary verb, and introducing moods interrogative, optative, promissive, hortative, precative, &c., we have exhibited such only as are obviously distinct; and which, whilst they are calculated to unfold and display the subject intelligibly to the learner, seem to be sufficient, and not more than sufficient, to answer all the purposes for which moods were introduced. ”
