English in Use/Verbs

Verbs are often called action words that show what the subject (a noun or pronoun) is doing. A verb is a word that signifies to be, to act, or to be acted on: as, I am, I rule, I am ruled, I love, you love, he loves. Verbs are so called, from the Latin verbum, a word; because the verb is that word which most essentially contains what is said in any clause or sentence. Although described as "action words", they can describe abstract concepts. They are a requirement of any sentence. Verbs have modifications of four kinds: moods, tenses, persons and numbers.

Morphological forms
An English verb has four morphological forms (forms of word formation) ever needful to be ascertained in the first place: the present, the past, the present participle, and the past participle. The third person singular is the fifth morphological form.

The present is that form of the verb, which is the root of all the rest; the verb itself; or that simple term which we should look for in a dictionary: as, be, act, rule, love, defend, terminate.

The past is that simple form of the verb, which denotes time past; and which is always connected with some noun or pronoun, denoting the subject of the assertion: as, I was, I acted, I ruled, I loved, I defended.

The present participle is that form of the verb, which ends commonly in ing, and implies a continuance of the being, action, or passion: as, being, acting, ruling, loving, defending, terminating.

The past participle is that form of the verb, which ends commonly in d or ed, and implies what has taken place: as, been, acted, ruled, loved.

Regularity
English, like many Germanic languages, contains both strong (or irregular, which is not quite the same as strong) and weak (regular) verbs. Irregular verbs are one of the most difficult aspects of learning English. Each irregular verb must be memorized, because they are not often easy to identify otherwise.

Verbs are divided, with respect to their regularity, into four classes: regular and irregular, redundant and defective.

A regular verb is a verb that forms the past and the past participle by assuming d or ed: as, love, loved, loving, loved.

An irregular verb is a verb that does not form the past and the past participle by assuming d or ed: as, see, saw, seeing, seen.

A redundant verb is a verb that forms the past or the past participle in two or more ways, and so as to be both regular and irregular: as, thrive, thrived or throve, thriving, thrived or thriven.

A defective verb is a verb that forms no participles, and is used in but few of the moods and tenses: as, beware, ought, quoth.

Persons and numbers
The person and number of a verb are those modifications in which it agrees with its subject. There are three persons and two numbers: thus,


 * 1) Singular first person. I love.
 * 2) Singular third person. He loves.
 * 3) Plural first person. We love.
 * 4) Plural second person. You love.
 * 5) Plural third person. They love.

Where the verb is varied, the third person singular in the present tense, is regularly formed by adding s or es: as, I see, he sees; I give, he gives; I go, he goes; I fly, he flies; I vex, he vexes; I lose, he loses.

Where the verb is not varied to denote its person and number, these properties are inferred from its subject: as, if I love, if he love; if we love, if you love, if they love.

Tenses
Tenses are those modifications of the verb, which distinguish time. There are three tenses - Each of the above category lists subcategories. One could even say there are twelve tenses because each of those comes in simple and in progressive forms, which have different meaning.
 * The Present,
 * The Past, and
 * The Future.

The past tense is sometimes called imperfect, but the names perfect and imperfect do not fit their meaning. These names were derived from Latin where they were correct.

The Present

Simple Present Tense is that which expresses what now exists, is normal or correlated to senses. It is used with adverbs like always, generally.


 * "There is a house in New Orleans."
 * "I read a book every week."
 * "I hear a noise."

Present Continuous Tense is that which expresses what is temporary:


 * "I am reading a letter."
 * "The car is running at high speed."
 * "Someone is always working."

Present perfect tense is that which expresses what has taken place, within some period of time not yet fully past, or is still valid. It is used with adverbs like ever, never, today, this week.


 * "I have read several of Shaw's novels."
 * "I have seen him today; something must have detained him."
 * "Have you ever tried fugu fish?"

Present perfect continuous tense is that which which started in the past and has not yet finished.


 * "Since I have been standing here, five planes took off."

The Past

Simple Past tense is that which expresses what took place in time fully past. It is used with adverbs like yesterday,  last week.


 * "Last week, I read several of Shaw's novels."

Past continuous tense is that which expresses what was taking place when (suddenly) something else occurred.


 * "I saw him yesterday, and hailed him as he was passing."
 * "I was giving a presentation when the microphone broke."

Past perfect tense is that which expresses what had taken place, at some past time mentioned, before something other happened.


 * "I had seen him, when I met you."
 * "As soon as my car had been repaired, I could continue my trip."

Past perfect continuous tense is that which expresses what had started before and was still going on, when something else occurred.


 * "I had been listening to the radio when she dropped in."

The Future

Simple Future Tense is that which expresses what will take place hereafter.


 * "I shall see him again, and I will inform him."

Future continuous tense is that which expresses what will be currently taking place at a certain time in future.


 * "I will be swimming in the sea by the time you'll awake."

Future Perfect Tense is that which expresses what will have taken place at some future time mentioned.


 * "I shall have seen him by tomorrow noon."

Future Perfect continuous Tense is that which expresses what will have started at some time and will still be ongoing, at some future time mentioned.


 * "I will have been swimming in the sea for four hours by the time you'll awake tomorrow."

Signification
An active verb is a verb in an active sentence, in which the subject performs the verb: as,


 * "I hit the dog."

An active verb can be transitive or intransitive, but not passive or neuter.

Verbs are divided again, with respect to their signification, into four classes: transitive, intransitive, passive, and neuter.

A transitive verb is a verb that expresses an action which has some person or thing for its object: as,


 * "Cain slew Abel."
 * "Cassius loved Brutus."

An intransitive verb is a verb that expresses an action which has no person or thing for its object: as,


 * "John walks."
 * "Jesus wept."

A passive verb is a verb in a passive sentence (passive voice) that represents its subject, or what the nominative expresses, as being acted on: as,


 * "I am compelled."
 * "Caesar was slain."

In a passive sentence, the action is performed on the subject.


 * "I hit the dog,"
 * "The dog was hit by me."

These sentences have the same denotative meaning, but their connotative meaning is quite different; active verbs are much more powerful and personal.

A neuter verb or impersonal passive verb is a verb that expresses neither action nor passion, but simply being, or a state of being: as,


 * "There was light."
 * "The babe sleeps."

Voice
Voice of speech can be active or passive. Principally in passive voice the same tenses can be used as in active voice. There are two forms of passive voice (the second form is preferred):


 * "He gave me the book." =>
 * "The book was given to me,"
 * "I was given the book."

There are however some things to note.


 * "They build a house."
 * "The house is built."

Here active and passive do not really have the same meaning. If for example you describe a picture where people build a house, the first sentence is perfectly correct. The second sentence however will be interpreted as the static perfect of the sentence


 * "The house has been built&mdash;it is built now."

This is, the house is now ready and not under construction. So the correct passive form is


 * "The house is being built."

Passive voice can be built quite formally by adhering to some rules. You will however not find normally all tenses as in active voice. Formal rules will lead you to monstrosities like the following, you will certainly never hear (already the active sentence is quite monstrous):


 * "The speech will have been being held for four hours when finally you'll arrive."
 * "The president will have been holding a speech for four hours when finally you'll arrive."

Moods
Moods are different forms of the verb, each of which expresses the being, action, or passion, in some particular manner.

There are five moods; the infinitive, the indicative, the potential, the subjunctive, and the imperative.

The infinitive mood is that form of the verb, which expresses the being, action, or passion, in an unlimited manner, and without person or number: as,


 * "To die,&mdash;to sleep;&mdash;to sleep!&mdash;perchance, to dream!"&mdash;from Hamlet by William Shakespeare.

The indicative mood is that form of the verb, which simply indicates or declares a thing: as,


 * "I write,"
 * "You know."

or asks a question: as,


 * "Do you know?"
 * "Know you not?"

The potential mood is that form of the verb which expresses the power, liberty, possibility, or necessity, of the being, action, or passion: as,


 * "I can walk."
 * "He may ride."
 * "We must go."

The subjunctive mood is that form of the verb, which represents the being, action, or passion, as conditional, doubtful, and contingent: as,


 * "If you go, see that you offend not."
 * "See you do it not."&mdash;Rev., xix, 10.
 * "God save the queen."
 * "It is a requirement that ... be done."
 * "It's high time you were in bed."
 * "If I were you,..."

The imperative mood is that form of the verb which is used in commanding, exhorting, entreating, or permitting: as,


 * "Depart you."
 * "Be comforted."
 * "Forgive me."
 * "Go in peace."

Conjugation
The conjugation of a verb is a regular arrangement of its moods, tenses, persons, numbers, and participles.

An auxiliary, or a sign of a verb, is a short verb prefixed to one of the morphological forms of another verb, to express some particular mode and time of the being, action, or passion. The auxiliaries are do, be, have, shall, will, may, can, and must, with their variations. Do, be, and have express the indicative mood.

Most often, the auxiliaries are used in the following way:


 * When talking about actions that take place in the future, add the word will before the verb.
 * To describe an action that is temporary, add the appropriate form of the verb be before the verb and add ing to the end of the verb root.
 * To describe an action that has taken place, put the verb in the past tense and add the appropriate form of the verb have before the verb.
 * You can combine the previous two auxiliaries by putting the appropriate form of have before been, and putting both of them before the verb.

Do

 * Present tense, sign of the present. I do, he does, we do, you do, they do.
 * Past tense, sign of the past. I did, he did, we did, you did, they did.

Be

 * Present tense, sign of the present. I am, he is, we are, you are, they are.
 * Past tense, sign of the past. I was, he was, we were, you were, they were.

Have

 * Present tense, sign of the perfect. I have, he has, we have, you have, they have.
 * Past tense, sign of the past perfect. I had, he had, we had, you had, they had.

Shall and will
Often confused with each other in modern English. These auxiliaries have distinct meanings, and, as signs of the future, they are interchanged thus:

Present tense, sign of the indicative first-future.


 * Simply to express a future action or event: I shall, he will, we shall, you will, they will.
 * To express a promise, command, or threat: I will, he will, we will, you will, they will.

Past tense, sign of aorist, or indefinite.


 * Used with reference to duty or expediency: I should, he should, we should, you should, they should.
 * Used with reference to volition or desire: I would, he would, we would, you would, they would.

See also: Shall and will by Wikipedia

May

 * Present tense, sign of the potential present. I may, he may, we may, you may, they may.
 * Past tense, sign of the potential past. I might, he might, we might, you might, they might.

Can

 * Present tense, sign of the potential present. I can, he can, we can, you can, they can.
 * Past tense, sign of the potential past. I could, he could, we could, you could, they could.

Must

 * Present tense, sign of the potential present. I must, he must, we must, you must, they must.

If must is ever used in the sense of the past tense, the form is the same as that of the present: this word is entirely invariable.

Is being
English grammar has changed,


 * "The house is being built."

no longer means the same as


 * "The house is built."

The first sentence refers to an ongoing action, the second to a completed one.


 * "If the expression, 'Is being built,' be a correct form of the present indicative passive, then it must be equally correct to say in the perfect, 'Has been being built;' in the past perfect, 'Had been being built;' in the present infinitive, 'To be being built;' in the perfect infinitive, 'To have been being built;' and in the present participle, 'Being being built;' which all will admit to be expressions as incorrect as they are inelegant, but precisely analogous to that which now begins to prevail."&mdash;Bullions's Principles of English Gram., p. 58.

Forms of conjugation
Verb may be conjugated in four ways:


 * Affirmatively: as, I write, I do write, or, I am writing; and so on.
 * Negatively: as, I write not, I do not write, or, I am not writing.
 * Interrogatively: as, write I? do I write? or, am I writing?
 * Interrogatively and negatively: as, write I not? do I not write? or, am I not writing?

The verbs would be conjugated affirmatively, unless said otherwise.

Love, conjugated in simple form
The verb love is a regular active verb.

Simple form, active or neuter
The simplest form of an English conjugation, is that which makes the present and past tenses without auxiliaries; but, even in these, auxiliaries are required for the potential mood, and are often preferred for the indicative.

Infinite mood
The infinitive mood is that form of the verb, which expresses the being, action, or passion, in an unlimited manner, and without person or number. It is used only in the present and perfect tenses.

Present tense
This tense is the root, or radical verb; and is usually preceded by the preposition to, which shows its relation to some other word: thus,


 * To love.

Perfect tense
This tense prefixes the auxiliary have to the past participle; and, like the infinitive present, is usually preceded by the preposition to: thus,


 * To have loved.

Indicative mood
The indicative mood is that form of the verb, which simply indicates or declares a thing, or asks a question. It is used in all the tenses.

Present tense
The present indicative, in its simple form, is essentially the same as the present infinitive, or radical verb; except that the verb be has am in the indicative.

The simple form of the present tense is varied thus:


 * I love, he loves, we love, you love, they love.

This tense may also be formed by prefixing the auxiliary do to the verb: thus,


 * I do love, he does love, we do love, you do love, they do love.

Past tense
This tense, in its simple form is the past; which, in all regular verbs, adds d or ed to the present, but in others is formed variously.

The simple form of the past tense is varied thus:


 * I loved, he loved, we loved, you loved, they loved,

This tense may also be formed by prefixing the auxiliary did to the present: thus,


 * I did love, he did love, we did love, you did love, they did love.

Perfect tense
This tense prefixes the auxiliary have to the past participle: thus,


 * I have loved, he has loved, we have loved, you have loved, they have loved.

Past perfect tense
This tense prefixes the auxiliary had to the past participle: thus,


 * I had loved, he had loved, we had loved, you had loved, they had loved.

First-future tense
This tense prefixes the auxiliary shall or will to the present: thus,


 * Simply to express a future action or event: I shall love, he will love, we shall love, you will love, they will love.
 * To express a promise, volition, command, or threat: I will love, he shall love, we will love, you shall love, they shall love.

Second-future tense
This tense prefixes the auxiliaries shall have or will have to the past participle: thus,


 * I shall have loved, he will have loved, we shall have loved, you will have loved, they will have loved.

Potential mood
The potential mood is that form of the verb, which expresses the power, liberty, possibility, or necessity of the being, action, or passion. It is used in the first four tenses; but the potential past is properly an aorist: its time is very indeterminate: as,


 * "He would be devoid of sensibility were he not greatly satisfied."&mdash;Lord Kames, El. of Crit., Vol. i, p. 11.

Present tense
This tense prefixes the auxiliary may, can, or must, to the radical verb: thus,


 * I may love, he may love, we may love, you may love, they may love.

Past tense
This tense prefixes the auxiliary might, could, would, or should, to the radical verb: thus,


 * I might love, he might love, we might love, you might love, they might love.

Perfect tense
This tense prefixes the auxiliaries, may have, can have, or must have, to the past participle: thus,


 * I may have loved, he may have loved, we may have loved, you may have loved, they may have loved.

Past perfect tense
This tense prefixes the auxiliaries, might have, could have, would have, or should have, to the past participle: thus,


 * I might have loved, he might have loved, we might have loved, you might have loved, they might have loved.

Subjunctive mood
The subjunctive mood is that form of the verb, which represents the being, action, or passion, as conditional, doubtful, or contingent. This mood is generally preceded by a conjunction: as, if, that, though, lest, unless, except. But sometimes, especially in poetry, it is formed by a mere placing of the verb before the nominative: as,


 * "Were I," for, "If I were;"
 * "Had he," for, "If he had;"
 * "Fall we" for, "If we fall;"
 * "Knew they," for, "If they knew."

It does not vary its termination at all, in the different persons. It is used in the present, and sometimes in the past tense; rarely, and perhaps never properly, in any other. As this mood can be used only in a dependent clause, the time implied in its tenses is always relative, and generally indefinite: as,


 * "It shall be in eternal restless change, self-fed, and self-consumed: if this fail, the pillared firmament is rottenness."&mdash;Milton, Comus, l. 596.

Present tense
This tense is generally used to express some condition on which a future action or event is affirmed. It is therefore erroneously considered by some grammarians, as an elliptical form of the future.


 * If I love, if he love, if we love, if you love, if they love.

In this tense, the auxiliary do is sometimes employed: as,


 * "If you do prosper my way."&mdash;Genesis, xxiv, 42.
 * "If he do not utter it."&mdash;Leviticus, v, 1.
 * "If he do but intimate his desire."&mdash;Murray's Key, p. 207.
 * "If he do promise, he will certainly perform."&mdash;Ib., p. 208.
 * "An event which, if it ever do occur, must occur in some future period."&mdash;Hiley's Gram., 3d Ed., Lond., p. 89.
 * "If he do but promise, you are safe."&mdash;Ib., 89.
 * "Until old experience do attain to something like prophetic strain."&mdash;Milton: Il Penseroso.

Past tense

 * If I loved, if he loved, if we loved, if you loved, if they loved.

This tense, like the past of the potential mood, with which it is frequently connected, is properly an aorist, or indefinite tense; for it may refer to time past, present, or future: as,


 * "If therefore perfection were by the Levitical priesthood, what further need was there that an other priest should rise?"&mdash;Heb., vii, 11.
 * "They must be viewed exactly in the same light, as if the intention to purchase now existed."&mdash;Murray's Parsing Exercises, p. 24.
 * "If it were possible, they shall deceive the very elect."&mdash;Matt., xxiv, 24.
 * "If the whole body were an eye, where were the hearing?"&mdash;1 Corinthians, xii, 17.
 * "If the thankful refrained, it would be pain and grief to them."&mdash;Atterbury.

 * Love [you,] or do you love.
