There are nine auxiliary or helping verbs, viz., Be, have, do, shall, will, may, can, ought, and must. They are called helping verbs, because it is by their aid the compound tenses are formed.
TO BE
The verb To Be is the most important of the auxiliary verbs. It has eleven parts, viz., am, art, is, are, was, wast, were, wert; be, being and been.
VOICE
The active voice is that form of the verb which shows the Subject not being acted upon but acting; as, "The cat catches mice." "Charity covers a multitude of sins."
The passive voice: When the action signified by a transitive verb is thrown back upon the agent, that is to say, when the subject of the verb denotes the recipient of the action, the verb is said to be in the passive voice. "John was loved by his neighbors." Here John the subject is also the object affected by the loving, the action of the verb is thrown back on him, hence the compound verb was loved is said to be in the passive voice. The passive voice is formed by putting the perfect participle of any transitive verb with any of the eleven parts of the verb To Be.
CONJUGATION
The conjugation of a verb is its orderly arrangement in voices, moods, tenses, persons and numbers.
Here is the complete conjugation of the verb "Love"—Active Voice.
(N. B.—Note that the plural form of the personal pronoun, you, is used in the second person singular throughout. The old form thou, except in the conjugation of the verb "To Be," may be said to be obsolete. In the third person singular he is representative of the three personal pronouns of the third person, He, She and It.)
ADVERB
An adverb is a word which modifies a verb, an adjective or another adverb. Thus, in the example—"He writes well," the adverb shows the manner in which the writing is performed; in the examples—"He is remarkably diligent" and "He works very faithfully," the adverbs modify the adjective diligent and the other adverb faithfully by expressing the degree of diligence and faithfulness.
Adverbs are chiefly used to express in one word what would otherwise require two or more words; thus, There signifies in that place; whence, from what place; usefully, in a useful manner.
Adverbs, like adjectives, are sometimes varied in their terminations to express comparison and different degrees of quality.
Some adverbs form the comparative and superlative by adding er and est; as, soon, sooner, soonest.
Adverbs which end in ly are compared by prefixing more and most; as, nobly, more nobly, most nobly.
A few adverbs are irregular in the formation of the comparative and superlative; as, well, better, best.
PREPOSITION
A preposition connects words, clauses, and sentences together and shows the relation between them. "My hand is on the table" shows relation between hand and table.
Prepositions are so called because they are generally placed before the words whose connection or relation with other words they point out.
CONJUNCTION
A conjunction joins words, clauses and sentences; as "John and James." "My father and mother have come, but I have not seen them."
The conjunctions in most general use are and, also; either, or; neither, nor; though, yet; but, however; for, that; because, since; therefore, wherefore, then; if, unless, lest.
INTERJECTION
An interjection is a word used to express some sudden emotion of the mind. Thus in the examples—"Ah! there he comes; alas! what shall I do?" ah, expresses surprise, and alas, distress.
Nouns, adjectives, verbs and adverbs become interjections when they are uttered as exclamations, as, nonsense! strange! hail! away! etc.
We have now enumerated the parts of speech and as briefly as possible stated the functions of each. As they all belong to the same family they are related to one another but some are in closer affinity than others. To point out the exact relationship and the dependency of one word on another is called parsing and in order that every etymological connection may be distinctly understood a brief resume of the foregoing essentials is here given:
The signification of the noun is limited to one, but to any one of the kind, by the indefinite article, and to some particular one, or some particular number, by the definite article.
Nouns, in one form, represent one of a kind, and in another, any number more than one; they are the names of males, or females, or of objects which are neither male nor female; and they represent the subject of an affirmation, a command or a question—the owner or possessor of a thing—or the object of an action, or of a relation expressed by a preposition.
Adjectives express the qualities which distinguish one person or thing from another; in one form they express quality without comparison; in another, they express comparison between two, or between one and a number taken collectively—and in a third they express comparison between one and a number of others taken separately.
Pronouns are used in place of nouns; one class of them is used merely as the substitutes of names; the pronouns of another class have a peculiar reference to some preceding words in the sentence, of which they are the substitutes—and those of a third class refer adjectively to the persons or things they represent. Some pronouns are used for both the name and the substitute; and several are frequently employed in asking questions.
Affirmations and commands are expressed by the verb; and different inflections of the verb express number, person, time and manner. With regard to time, an affirmation may be present or past or future; with regard to manner, an affirmation may be positive or conditional, it being doubtful whether the condition is fulfilled or not, or it being implied that it is not fulfilled;—the verb may express command or entreaty; or the sense of the verb may be expressed without affirming or commanding.
