423. We have already found that the verb alone is sometimes quite enough to make a finished predicate; as in
| The earth revolves. The sun rises. |
But sometimes it seems only to have begun what another word must finish; as in
| The sun gives light. The earth is a sphere. |
Hence we class verbs as Complete and Incomplete.
|
424. Incomplete verbs, or those that need complements, are again divided into classes as follows:
Copulative verbs that need a complement to describe what the subject refers to; as,
| Fire is hot. We were without food. Heat is a force. |
Transitive verbs that need an object to show what the action affects; as,
| The sun gives light. Burn the trees. |
|
|
425. Of these three kinds of verbs, complete, compulative, and transitive, the two that are not complete may, of course, be called incomplete, and the two that are not transitive may be called intransitive.
|
426. Copulative Verbs. No verb is always copulative, and only a small number are ever so; one of them however is extremely common, namely, be, which with its various forms, am, is, was, were, etc. helps to make many verb phrases; as in
| We are waiting, for We wait. |
( a ) Be is sometimes used like exist as a complete verb with more of a basic meaning; as in
| The time was, when no one lived here; There is a God; |
but generally it seems only to connect the subject to what is asserted of it.
( b ) Be enters into the meaning of all other copulative verbs.
Thus:
| He appeared wise. | = He was wise in appearance. |
| The clouds look distant. | = The clouds are distant in the sight. |
| The water tastes bitter. | = The water is bitter to the taste. |
|
So with feel, sound, smell, become, seem, etc.
|
|
433. The Present tense of a verb is the form that generally refers to present time.
As,
|
434. The present tense is sometimes used of what is past or future to make it seem present or distinct; as,
| In the fifteenth century a new era begins. |
| We leave the city tomorrow. |
|
|
|
435. In form the present tense is like the simple infinitive, or root, from which all other forms are derived.
|
436. The Past tense of a verb is the form that generally refers to past time.
As,
| I stood; I worked; I lived. |
|
437. The past tense is sometimes used of what is really present or future to make it seem doubtful; as,
| If I were well today If I should go tomorrow |
|
438. The common or regular way of changing the present to the past form is by adding -d or -ed at the end.
Thus:
| I lived; I borrowed; I waited. |
But in a number of the oldest verbs the change appears in the middle of the word, whether anything is added or not.
Thus:
| stand, stood; fall, fell; see, saw. |
|
441. If we study verbs in sentences, we find them used to predicate in several ways or modes.
Thus, they may be used
1. To command, as in Be ready; Wish with me.
2. ( a ) To assert positively, as in I am ready; She wishes it.
( b ) To question, as in Am I ready? Who wishes this?
3. To say something doubtfully, as if only thought of; as in If it be there, I will bring it; If I were ready, I would go.
|
|
442. It was once the custom to use in such cases quite different forms of the verb called not tenses to show times but Moods to show the manner or mood in which a person spoke.
Even nowadays the forms are not always the same, and hence we may say that
|
443. I. A verb used to express a command or a request is in the Imperative mood.
As,
| Go quickly. Come with me. Be honest. |
|
444. II. A verb used either (1) to state something as a fact, or (2) to ask a simple question, is in the Indicative mood.
As,
| He goes quickly. Does she wish it? |
| If she was there, I failed to see her. |
Most sentences are, as we know, of this kind.
|
445. III. A verb used to express in a doubtful way either (1) what is uncertain and to be decided in the future, or (2) a supposition that is contrary to fact, or (3) a wish, is in the Subjunctive mood.
As,
(1) Though he be dead, we shall find him. Even if he fail, he will not despair.
(2) If she were willing, I would help her.
(3) I wish I were well. Thy kingdom come.
Sentences of this kind are comparatively rare.
|
446. We know that the order of words may distinguish an assertion from a question; as in
| Does he drive? He does drive. |
and also that the dropping of the subject may distinguish an assertion from a command; as in
| You drive every day; Drive every day. |
Now commonly there is nothing about the form of a verb to show in what manner it is used; but still there are a few special forms in the indicative mood, so that even now the form does sometimes vary with different modes of speaking.
Thus:
| INDICATIVE FORMS. |
| 1. Thy foe appears; advance. |
| 2. Thine enemy thirsts; give him drink. |
| 3. He telleth all our plans. |
| 4. He said he was to stay. |
| 5. I know what the result is. |
| INDICATIVE FORM. |
| 1. Thou keepest my feet from falling. |
|
| SUBJUNCTIVE FORMS. |
| 1. If thy foe appear; advance. |
| 2. If thine enemy thirst; give him drink. |
| 3. See that he tell no man our plans. |
| 4. He said if he were to stay,
. |
| 5. Whatever be the result
. |
| IMPERATIVE FORM. |
| 1. Keep thou my feet from falling. |
|
|
|
447. When used with the same subject, such forms as appears, thirsts, telleth, was, is, am, art, are, belong only to the indicative mood;
such forms as appear, thirst, tell, were, be, belong only to the Subjunctive mood.
Forms like keep instead of keepest belong to the Imperative mood.
[For Potential phrases, see § 483.]
|
|
448. Mood is the power of a verb to denote the manner of speaking.
|
449. The differences in the special indicative forms of a verb depend on what its subject is.
Thus, in the present tense we say,
I, we, you, they, or the men stay; but He, she, it, or the man stays, |
using a special form made by adding -s or -es whenever the subject is a third singular pronoun or a singular noun.
|
|
450. As this special form is never used except with a subject denoting the third person and the singular number, it is called the third singular form.
It is also calle the s-form, because it always ends in -s.
|
454. From almost every verb are formed two special kinds of verbal words having the use of other parts of speech.
Thus, besides true verbs drives, drove, we have the two nouns, driving and (to) drive, that name theaction expressed by the verb; as in
| Driving is pleasant; I like to drive. |
and two adjectives, driving; and driven, that describe either the actor or the receiver of the action; as in
| A man driving a car; Snow driven by the wind. |
|
455. Such nouns and adjectives as these differ from all others that are derived from verbs, since they may be formed from almost any verb; and, what is still more important to notice, they may have the same modifiers and complements that their corresponding verbs have.
Thus:
(1) The nouns, if derived from transitive verbs, may take an object.
As in
| Driving fast cars is pleasant; |
and they always may be modified by an adverb.
As in
Here driving and to drive are used as subject and object, respectively; but, like verbs, they express action as passing over to something else, or as going on in different ways.
(2) So with adjectives, we may say,
| a man beating a dog, or a dog cruelly beaten. |
Here beating and beaten describe the man and the dog like adjectives, and are modified like verbs.
There is no assertion in either expression, yet we think of the man as acting and of the dog as acted upon, as much as if a verb were used.
|
458. An Infinitive and a Gerund are verbal nouns that name the action or condition expressed by the verb, and take the same complements and modifiers.
The word infinitive means infinite, unlimited.
It is applied to the first noun form because the idea of the verb is never limited as to person and number.
The word gerund means fit to bear.
It is applied to the second noun form because the verb can carry its modifiers and complements with it.
|
|
459. The two adjectives regularly formed from verbs are called Participles.
|
460. One participle describes a person or thing as continuing an action.
It is called the active or present participle, and always ends in -ing; as,
| driving, spinning, sleeping, walking. |
|
461. The other participle is called the passive or past participle, because what it decribes is regarded either ( a ) as having received the action expressed by the verb; as in
| Threads are spun, Cars are driven. |
or else ( b ) as having completed some action; as in
| One who has walked or slept. |
This participle usually ends in -t, -d, or -n.
The names imperfect and perfect are also used.
