The indefinite form of the verb runs. What is the indefinite form of the verb and what is its role

Instruction

You can determine the infinitive by the question. Find a verb and ask a question to it. If this is a verb in an indefinite form, then it will answer the question “what to do?”, “what to do?”. For example, grow, bake, flood, breed, lie down.
At the end of such verbs always soft sign.

It is difficult to distinguish the infinitive from the personal form if the word is written in transcription. The record of the finals of these forms is the same: [tutor "itsa] (studies) - [tutor" ita] (studies). In this case, pay attention to , the vowel before [-ca] or the context where you can ask a question. If this work is not feasible, then both forms are appropriate.

The indefinite form of the verb is included in the compound nominal predicate. In this case, the sentence contains two heterogeneous verbs. To determine which one is the infinitive, you need to designate grammatical basis. The predicate will consist of two verbs. The one that contains the lexical meaning is the infinitive, it needs a soft sign. So, in the sentence "Students will be able to work out additionally" the predicate "will be able to work out." And the indefinite form is "to work out."

The indefinite form of the verb can act as secondary members of the sentence. In such cases, it can be determined by following the logic of reasoning. Ask a question of the indirect case from the predicate to the infinitive. If possible, then in this case it is an addition. For example, in the sentence “The coach told us to do a warm-up”, the word “do” will be an object (said what?). In this case, reason like this: the action indicated in the verb “ordered” is performed, and others will perform it. So this is not a predicate, because it is simple.

Circumstances expressed in the indefinite form of the verb most often answer the questions “for what purpose?”, “For what reason?”. In the sentence “I came to the gym to train”, we ask the question “I came for what purpose?” to the infinitive.
By definition ask a question from . In the sentence “I am fluent in the ability to play the guitar”, the infinitive is -: the ability (what?) to play.

note

Only in one-part sentences with the main member of the predicate there are no words from which a question is asked to the verb.

Helpful advice

Ask questions from one word to another. If the minor member is expressed by a verb, then this is only an indefinite form. Be sure to write a soft sign.

A verb is a part of speech with permanent and non-permanent features. The person of the verb is its inconstant sign, and only verbs in the present and future tenses have it. Not everyone can immediately identify it. To do this, we will give a short instruction on how to determine the person of the verb.

You must know that indefinite form verb often called the infinitive. The verb in this form does not change either in numbers or in persons. It is impossible for him to determine both inclination and appearance.

You can, of course, form an indefinite form of the verb with the help of auxiliary questions “what to do?”, “what to do?”. But this method may not always be useful to you. So, it is difficult for schoolchildren to put in the infinitive impersonal verbs, which in the future may be the result of spelling errors.

Children also confuse third person verbs with the infinitive, which means they will not be able to determine whether to write: "tsya" or "tsya". For example, to the verb in the syntactic construction “seems to be successful”, children find it difficult to put auxiliary questions “what to do?”, “what to do?”. Thus, they will not be able to check the spelling of .

Finding the indefinite form of a verb or forming it is easier, paying attention to some details. So, you should know that the infinitive has the ending "t" or "ti". For example, in "bring" the ending will be "ti", and in the word "in time" - "t".

The ending "ti" is in an indefinite form if it is preceded by a vowel sound, and "t" is after a consonant. So, in the infinitive "bloom" before the end of "ti" there is a consonant sound "s", and in the word "see" - the vowel "e".

To learn how to form an indefinite form, it is necessary to ask the questions “what to do?” or "what to do?" And do not forget to pay attention to the structure of the word.

The noun is a separate part of the speech of the Russian language. It has the forms of number and case, which classify the categories of gender, as well as animateness and inanimateness, depending on the objects designated.

Instruction

Imagine several variants of the same thing: “home”, “home”, “home”. How to determine its initial form(or dictionary form)? The initial form of the noun is the nominative form. This case denotes the concept expressed by the word. Most often, the names in this case play the role of the subject in the sentence, less often - the predicate. Nominative to the questions: “who?”, “What?” Like what?" - "house", "who?" - "bird". Ask similar questions to determine form noun.

Recall from school curriculum, which is in the initial form, in most cases is in the singular. Therefore, in order to define vocabulary form this part of speech, put it in the singular: “many houses” - “one house”.

Note that some nouns only have form plural, and it is impossible to modify them, leading to the singular. These include, for example, the names of time periods, paired objects, masses of matter: “day”, “glasses”, “trousers”, “weekdays”, “pasta”, “holidays”, “ink”, “scissors”. The initial form of similar is the nominative plural form.

Pay attention to the need for homonyms (words that are the same in sound and spelling, but different in meaning) from each other. For example: “A clock hangs on the wall” (here “clock” will have the initial form only in the plural). Or: “At these hours the sky is usually

Infinitive, or indefinite form of the verb

A verb in its initial or indefinite form is called an infinitive. The infinitive always answers the question "what to do?" or "what to do?" It is never possible to ask questions in relation to the initial form: “what is she doing?”, “What will she do?”, “What will she do?”, “What did she do?”, “What did she do? " etc. That is, the infinitive, by definition, has minimal amount morphological features.

Examples. The verb "go" answers the question "what to do?". Accordingly, it is a verb in an indefinite (initial) form, or an infinitive. However, the verbs “goes”, “will go”, “go” answer the questions “what is he doing?”, “what will he do?”, “?”. These verbs already have morphological features - persons, numbers and tenses - and are not infinitives.

Another example. The verb "write" answers the question "what to do?" and is an infinitive. From this initial form verbs are formed in the past and future tenses, first, second and third persons, singular and plural: “wrote”, “wrote”, “”, “”, “will write”.

In other words, the verb in the infinitive is always the zero (indefinite) form, from which you can always form different forms of the same word in different persons and numbers. This process is called conjugation.

What features of the verb can be determined by the initial form

If the infinitive is the initial, zero, indefinite form of the verb, is it possible to determine any signs of this part of speech, or morphological signs, from it? Yes, you can define constants, signs of the verb.

Firstly, according to the indefinite form, it is possible to determine the types of the verb - perfect or. The imperfective verb in the initial form answers the question "what to do?" and denotes an unfinished action. For example, “walk”, “”, “sing”, “”, etc. The perfective verb in the infinitive answers the question "what to do?" and denotes a completed, finished action. For example, “walk”, “read”, “sing”, “compose”, “fly”, etc.

Secondly, by the infinitive you can determine. There are two conjugations - the first and the second. The first conjugation includes all verbs that in the infinitive end in -et, -at, -ut, -ot, -t, -yt, and a few exception verbs in -it. The second conjugation includes most of the verbs in -it, as well as some exception verbs in -at, -yat and -et.

The infinitive is an indefinite or initial form verb. It would seem, what a simple thing! But this linguistic phenomenon also has its own characteristics and even "pitfalls", about which will be discussed later in this article.

Brief description of the infinitive in Russian

An infinitive verb is what we see written in a dictionary entry. It has no mood, person, number, time, that is, it does not change depending on who performs the action, since there is simply no such subject. However, such a verb still has some features - aspect (perfect or imperfect) and conjugation (first or second). In addition, it is characterized by recurrence or irreversibility, as well as transitivity or intransitivity.

How to understand that the verb is in the infinitive

To determine that a given form of an action word is in fact an infinitive, you need to ask questions of the indefinite form of the verb to it. These include: " what to do?' (for example, 'read' or 'talk') or ' what to do?" (for example, "gift" or "drink"). If the verb answers them, then it is in the initial form.

In addition, in the infinitive in Russian there are always suffixes: -t-, -ti-, -ch-, -st- and -sti-. It is worth noting that some linguists argue that these are the endings of indefinite verbs, since this morpheme is subject to change. However, the controversy has not subsided so far.

What is the indefinite form of the verb used for?

The Russian language is rich enough in various possibilities of using the infinitive. The indefinite form of the verb can be the subject, predicate, definition, object in the sentence, and also be an integral part verbal predicate, to express imperative mood or future tense. Next, we will consider each of these cases in more detail with examples.

Specific syntactic roles of the verb in the initial form

So, the verb in the indefinite form is the subject, if it is somehow characterized. For example:

  • Drawing was the meaning of his life.
  • Being a mother is the meaning of Svetlana's life.

In these proposals paint" And " to be (mother)» are subject, as they are separate, independent actions.

In addition, a sentence can contain two infinitives, one of which characterizes the other:

  • To live means to love.

Then here" live" is the subject, and " be in love"- predicate. In this case, the member of the sentence is easily determined: the subject goes before the predicate. Also instead of " Means" can be a dash or the words " this", "is» and the like.

An infinitive can be a definition if it is in this form, for example:

  • He went to bed determined to read a book tomorrow.

It turns out that the verb "read" here answers the question "what kind?" With what decision did he go to bed? Read (tomorrow a book). That is, a verb of an indefinite form is a definition if it refers to a noun, which means necessity, decision, desire, expression of will, and the like.

The indefinite form of the verb is also an object if, for example, it is used in such a phrase:

  • Dad asked Lena to pick up the pencil.

That is, the verb "asked" here has a full-fledged lexical meaning. Both verbs refer to different peopleasked"to dad, and" raise"- to Lena).

The infinitive is an integral part of the verbal predicate if used with a verb that denotes the beginning, continuation or completion of an action, that is, it has an auxiliary meaning. For example:

  • The puppy quickly began to fall asleep.
  • The teacher continued teaching.

"Began" And " continued" are just such verbs, therefore " fall asleep" And " lead" will be parts of the predicate.

The infinitive expresses the imperative when used in a commanding tone. For example, a squad leader might order: Be silent!", and the captain of the ship shout:" All hands on deck!»

The initial form of the verb expresses the future tense in sentences like this:

  • Yes, Ivan should not be a pilot!

That is, it must contain a certain shade of annoyance or regret.

Common spelling mistakes

In most cases, an infinitive verb is an easy thing to spell, but sometimes people get confused. This happens when the verb is reflexive. The soft sign in front of the suffix is ​​simply forgotten - Xia-, so it turns out that the verb is in the third person and singular. And sometimes it makes it very difficult to understand when reading.

In order to avoid mistakes and correctly write suffixes (or the endings of indefinite verbs), you need to mentally ask them questions every time: “h what to do?"or" h then do?» If the verb clearly answers exactly to them, it is necessary to put a soft sign. For example, in the last word in the sentence " Petya is going to sleep tonight" put a soft sign, because Peter going what to do? Get enough sleep.

Thus, the indefinite verb is a rather interesting and important part of the language that can be used in different occasions, the main thing is to learn them well.

If you want, remember.

Verbs that answer the question what to do? are imperfective verbs. Verbs that answer the question what to do? are perfective verbs.

Verbs that answer the questions what to do? and what to do?, are considered different words , even if they are the same root. They differ from each other in some parts of the basis and therefore are different in meaning.

What to do?

shake

speak

What to do?

The words are distinguished by the prefix za- (the prefix za- means "to start the action").

shake(root press -) - shake(root zha-)

The verb to shake refers to an action that is performed often (repeatedly), the verb to shake refers to an action that is performed once (once).

speak - agree

The words are distinguished by the prefix do- (the prefix do- means "finish the action").

In order not to switch from one verb to another, you need to follow the prefix in the question.

1. Put a question to the form of the verb and find out if there is a prefix C in the question - or not.

2. Ask a question of indefinite form with or without the prefix C-.

3. Name the indefinite form of the desired verb.

The indefinite form of the verb most often ends in -ty or -ty(go , get out , find , carry , crawl ). Scientists have not yet agreed on how to call this part of the word. Some consider it an ending, while others consider it a suffix.

Sometimes the indefinite form of the verb ends in -chi, but these letters are part of the root:

guard - guard(root guard-, guard-), lie down - lie down(root lie-, lie down-).

In the indefinite form of verbs, if it ends in something other than -ti, it is always written ь. It is also written after the letter h (-ch) - this is the spelling for the rule: ь in the indefinite form of the verb.

Determine the tense of the verbs and find the indefinite form.

flowed- what did you do?, prosh.v., what to do?, leak(root tech-flow)

shearing- what do I do ?, present in., what to do ?, cut(root cut-cut)

save save(root shore-protect)

I will carry away- what will I do ?, bud.v., what to do ?, captivate(root attract-attract)

Vowel letters in the indefinite form of verbs before -t are most often suffixes. They can be different: -a, -e, -i, -i, -o.

If they are unstressed, then there is always a spelling in their place. These letters-suffixes cannot be determined by the rule, they can only be learned from a dictionary and memorized.

Suffix -a: hear, swim, jump, listen

Suffix -e: see, offend, depend

Suffix -i: build, iron, cook, glue, put, build

Suffix -i: bark, melt, winnow, sow

You just need to listen.(V. Semernin)

What is he doing?, sings, sighs, lives- verbs in the present tense.

What to do?, listen - verb in the indefinite form.

The infinitive is the initial meaning of the verb. The peculiarity of the infinitive is that it denotes only a pure action, not tied to the person who performs it, does not indicate whether one or more persons perform the action, and also does not give an idea of ​​the time of the action. That is, the infinitive does not have the definiteness of the past, present or future tense.

This part of speech is also called the "indefinite form of the verb", because it does not characterize any details of the action being performed, revealing only its original meaning. latin word infintus, from which the term is derived, can be translated as "uncertain".

The indefinite form of the verb: rules and examples

The infinitive can only answer questions:

  • "What to do?";
  • "What to do?".

It is impossible, for example, to ask "Doing what?""What is he doing?","What are we doing?""What are they doing?""What you are doing?","What did you do?""What will you do?", since the infinitive is the indefinite form of the verb. Time and face remain unclear, and no reference is made to the details of what is happening.

Infinitive suffixes

The infinitive ends with word-forming suffixes:

  • -t - give birth, grow up, die;
  • -ch, - protect, burn, flog;
  • -ti - carry, grow, row.

It can also be supplemented with a postfix -s (s), by which we can judge which indefinite form of the verb is irrevocable, and which is reflexive:

-s (-sya) - toil, pray, beware.

Signs of the infinitive

The infinitive is the form of the verb that always remains the same. It cannot be conjugated, presented in a different time or person. Infinitives can only have constant verbal features that are present in any verb, regardless of their form. Such signs include transitivity/intransitivity, recurrence/irreturnability and perfection/imperfection.

Transitive and intransitive infinitives

The transitivity of the verb is determined in accordance with the presence of an additional word of the indefinite form of the verb, denoting an object or phenomenon, to which the action is partially transferred. Intransitive verbs consist of a single word denoting the action itself. The transitive infinitive can include:

  • nouns or pronouns put in the accusative case without a preposition: make an injection, thread;
  • nouns put in the genitive case, without a preposition, which express the share of something, or involvement: wait for trouble, pour water;
  • nouns or pronouns put in the genitive case, if the verb has a negative expression: be unable to notice them.

Thus, these words are part of the verb, filling it with meaning, and without them the essence of the action is lost. Part of the action, in turn, goes to the object or circumstance, giving it a specific semantic load.

Reflexive and irrevocable infinitives

The indefinite form of the verb can also be reflexive and non-reflexive. Irreversible verbs express an action performed by someone or something in relation to someone or something. Returns express an action directed by someone or something on itself, or mean another closed interaction or state of the object and have a postfix at the end -sya (sya). On -sya the reflexive indefinite form of the verb usually ends. The rule says that reflexive verbs cannot be transitive.

Examples of irrevocable infinitives: put on, put on, peek. Examples of reflexive infinitives: get dressed, get down, sneak.

As we can see from the above examples, some reflexive verbs can be obtained from non-reflexive ones by simply adding a postfix -sya(as in the case of the pair " lower-lower"). This only changes the direction of the action, but the general meaning remains. In rare cases, according to the rules and norms of the use of verbs, it is impossible to use the verb in both its word forms - perfect and imperfect, as, for example, the reflexive indefinite form of the verb is unacceptable for "put on" (example " put on-dress"). "Put on" denotes an action performed in relation to some object or person, while "dress" can refer exclusively to the object that performs the action (it can be used in other word forms, but provided that this reflexive meaning is preserved) . Although such a limited indefinite form of the verb is not often encountered, the rule remains the rule. Also, from some imperfect forms of verbs, we will not be able to make a perfect one, based on their key meaning, which we can see on the example of the verb "peep" - you can’t peep behind yourself. By the same principle, in Russian there is no imperfect form of the verb "sneak" - you can't " sneak"anything.

Perfect and imperfect infinitives

Infinitives can also be perfective or imperfective. The indefinite form of the imperfective verb expresses actions that continue in time and do not have a specific binding - these are, as it were, eternal actions, and without additional indications in the context, it does not give us an idea of ​​the completion or incompleteness of the action. A question would be relevant here. "What to do?". Examples:

Perfective infinitives say that the action has already been done, or will certainly be done, that the result is already there, or will still be (of course, in cases of negation or question, it may have a relatively indefinite coloring). A question would be relevant here. "What to do?". Examples:

  • After reading the note should have been burned.
  • Thank me that you didn't have to burn that note.
  • Were you instructed to burn the note?

Only a small number of dual infinitives contain Russian. The indefinite form of the verb, which is both perfective and imperfective, can be used this way and that, depending on the environment, without changing its word form. That is, she answers the question "What to do?", and to the question "What to do?". Examples:

  • An order was issued to continue to execute all traitors. - "What to do?";
  • An order was given to execute the traitor. - "What to do?";
  • In the village they are used to marrying girls quickly. - "What to do?";
  • By autumn, Martha managed to marry all her girls. - "What to do?";
  • It's hard to tell your heart. - "What to do?"
  • How to tell your heart not to love? - "What to do?"
  • Exploring caves is very interesting, but at the same time dangerous. - "What to do?"
  • Tomorrow we have to explore these caves. - "What to do?"
  • You can attack them from any direction, while I will smash them head on. - "What to do?"
  • You will have to attack them from the right, and I will go in from the flank. - "What to do?"

Conjugation of verbs

The conjugation of verbs reflects their change in accordance with person and number. Although the infinitives themselves cannot have a person, number or gender, and, therefore, cannot be conjugated, they nevertheless serve as a derivational basis for other verbs, therefore they are assigned to any of the two verb groups according to the type of conjugation - either to I , or to II. The endings of indefinite verbs related to the first group: -e, -yu(except for verbs of exceptions). The forms of these verbs have endings -u and -yu, -eat and -eat, -eat and -eat, -eat and -eat, -eat and -ete. The endings of indefinite verbs related to the second group: -And and on -I(except for verbs of exceptions). When conjugated, the forms of these verbs have endings -u and -yu, -ish, -it, -im, -ite, -at and -yat.

Function of the infinitive in a sentence

Verbs, as usual, perform the function of a predicate in a sentence. Together with the subjects, they form the grammatical basis of sentences. However, the infinitive, due to its peculiarities of use, can perform completely different functions in a sentence. Therefore, the role of any of the members of the sentence in this case can be performed by the indefinite form of the verb. An example of the use of infinitives as various members of a sentence:

Morphological analysis of the infinitive in a sentence

To carry out the morphological analysis of a verb in a sentence, it is necessary to determine its part of speech, general grammatical meaning, ask him questions, determine the word form, indicate permanent and non-permanent morphological features, as well as his function in the sentence. Since the indefinite form of the verb does not change, the morphological analysis of the infinitive is carried out without indicating inconstant verbal features.
