6. How can we distinguish a PARTICIPLE? By observing its derivation from the verb, and then placing it after to be or having; as, To be writing, Having written--To be walking, Having walked--To be weeping, Having wept--To be studying, Having studied. Of simple participles, there are twice as many as there are of simple or radical verbs; and the possible compounds are not less numerous than the simples, but they are much less frequently used.
7. How can we distinguish an ADVERB? By observing that it answers to the question, When? Where? How much? or How?--or serves to ask it; as, "He spoke fluently." How did he speak? Fluently. This word fluently is therefore an adverb: it tells how he spoke. Of adverbs, there are about two thousand six hundred; and four fifths of them end in ly.
8. How can we distinguish a CONJUNCTION? By observing what words or terms it joins together, or to what other conjunction it corresponds; as, "Neither wealth nor honor can heal a wounded conscience."--Dillwyn's Ref., p. 16. Or, it may be well to learn the whole list at once: And, as, both, because, even, for, if, that, then, since, seeing, so: Or, nor, either, neither, than, though, although, yet, but, except, whether, lest, unless, save, provided, notwithstanding, whereas. Of conjunctions, there are these twenty-nine in common use, and a few others now obsolete.
9. How can we distinguish a PREPOSITION? By observing that it will govern the pronoun them, and is not a verb or a participle; as, About them--above them--across them--after them--against them--amidst them--among them--around them--at them--Before them--behind them--below them--beneath them--beside them--between them--beyond them--by them--For them--from them--In them--into them, &c. Of the prepositions, there are about sixty now in common use.
10. How can we distinguish an INTERJECTION? By observing that it is an independent word or sound, uttered earnestly, and very often written with the note of exclamation; as Lo! behold! look! see! hark! hush! hist! mum! Of interjections, there are sixty or seventy in common use, some of which are seldom found in books.
OBS. 2.--An accurate knowledge of words, and of their changes, is indispensable to a clear discernment of their proper combinations in sentences, according to the usage of the learned. Etymology, therefore, should be taught before syntax; but it should be chiefly taught by a direct analysis of entire sentences, and those so plainly written that the particular effect of every word may be clearly distinguished, and the meaning, whether intrinsic or relative, be discovered with precision. The parts of speech are usually named and defined with reference to the use of words in sentences; and, as the same word not unfrequently stands for several different parts of speech, the learner should be early taught to make for himself the proper application of the foregoing distribution, without recurrence to a dictionary, and without aid from his teacher. He who is endeavouring to acquaint himself with the grammar of a language which he can already read and understand, is placed in circumstances very different from those which attend the school-boy who is just beginning to construe some sentences of a foreign tongue. A frequent use of the dictionary may facilitate the progress of the one, while it delays that of the other. English grammar, it is hoped, may be learned directly from this book alone, with better success than can be expected when the attention of the learner is divided among several or many different works.
OBS. 3.--Dr. James P. Wilson, in speaking of the classification of words, observes, "The names of the distributive parts should either express, distinctly, the influence, which each class produces on sentences; or some other characteristic trait, by which the respective species of words may be distinguished, without danger of confusion. It is at least probable, that no distribution, sufficiently minute, can ever be made, of the parts of speech, which shall be wholly free from all objection. Hasty innovations, therefore, and crude conjectures, should not be permitted to disturb that course of grammatical instruction, which has been advancing in melioration, by the unremitting labours of thousands, through a series of ages."--Wilson's Essay on Gram., p. 66. Again: "The number of the parts of speech may be reduced, or enlarged, at pleasure; and the rules of syntax may be accommodated to such new arrangement. The best grammarians find it difficult, in practice, to distinguish, in some instances, adverbs, prepositions, and conjunctions; yet their effects are generally distinct. This inconvenience should be submitted to, since a less comprehensive distribution would be very unfavourable to a rational investigation of the meaning of English sentences."--Ib., p. 68. Again: "As and so have been also deemed substitutes, and resolved into other words. But if all abbreviations are to be restored to their primitive parts of speech, there will be a general revolution in the present systems of grammar; and the various improvements, which have sprung from convenience, or necessity, and been sanctioned by the usage of ancient times, must be retrenched, and anarchy in letters universally prevail."--Ib., p. 114.
OBS. 4.--I have elsewhere sufficiently shown why ten parts of speech are to be preferred to any other number, in English; and whatever diversity of opinion there may be, respecting the class to which some particular words ought to be referred, I trust to make it obvious to good sense, that I have seldom erred from the course which is most expedient. 1. Articles are used with appellative nouns, sometimes to denote emphatically the species, but generally to designate individuals. 2. Nouns stand in discourse for persons, things, or abstract qualities. 3. Adjectives commonly express the concrete qualities of persons or things; but sometimes, their situation or number. 4. Pronouns are substitutes for names, or nouns; but they sometimes represent sentences. 5. Verbs assert, ask, or say something; and, for the most part, express action or motion. 6. Participles contain the essential meaning of their verbs, and commonly denote action, and
