Taking your first steps in learning English, you will definitely come across the verb to have. This verb has several functions, is an integral part of a huge number of expressions, turns and phrases. Its first meaning is "to have", "to possess", "to own". But a word can change meaning when used in combination with other lexical items. We will start with a simple one and consider two forms of the verb - have / has, the rule for their use and see how the verb to have and the verb have got differ from each other.

In this sense, the verb can be replaced by an alternative construction have got with the same meaning.

• I have got a funny rabbit - I have a funny rabbit.
• He has got a small kitten - he has a small kitten.

Both a single verb and the have got construction are used when it comes to owning something, in particular, about family ties and diseases.

Verb to have: meaning and rules of use

Taking your first steps in learning English, you will definitely come across the verb to have. This verb has several functions, is an integral part of a huge number of expressions, turns and phrases. Its first meaning is "to have", "to possess", "to own". But a word can change meaning when used in combination with other lexical items. We will start with a simple one and consider two forms of the verb - have / has, the rule for their use and see how the verb to have and the verb have got differ from each other.

Lexical meaning of the verb to have

The main meaning of the word, as noted above, is “to have”, “to own”, however, when translating into Russian, the structure “(someone) has” is more often used.

• I have a delicious cake - I have a delicious cake.
• He has a new car - he has a new car.

In this sense, the verb can be replaced by an alternative construction have got with the same meaning.

• I have got a funny rabbit - I have a funny rabbit.
• He has got a small kitten - he has a small kitten.

Both a single verb and the have got construction are used when it comes to owning something, in particular, about family ties and diseases.

In some set expressions (have a look, have breakfast, have a rest, etc.), the word got is not used.

Also, the verb to have changes its semantic meaning when it acts as a modal verb.

• We have to see him right now - we need to see him right now.
• You have to add some sugar - you need to add some sugar.

Grammatical forms of the verb to have

As you can see, in the examples above, the two forms alternate. So, when is it written have, and when is has?

The have form in English is used with the pronouns I, you, we, they (I, you, you, we, they), has - only with the pronouns he, she, it (he, she, it). But this rule does not apply in all tenses: in the future tense (Future Simple) after the auxiliary verb will in all persons put have.

Do and Does in English

When we first encounter verbs in English, each of us has certain difficulties with their conjugation. Just in case, let me remind you that conjugation is a change of a verb in persons, numbers and tenses. We, without hesitation, conjugate Russian verbs.

For example, the verb "see"

We are not at all embarrassed that in the first person (I), the root vowel changes from d to zh. We are used to this, we also need to get used to some of the peculiarities of the conjugation of English verbs.

In this article we will talk about the verb to do(do, perform an action).

As you may have guessed, do and does are forms of the verb to do in present simple(i.e. simple present).

rule very simple:

in 1st person singular and plural (I, we), as well as in the 2nd and 3rd person plural (you, they) → DO

third person singular (she/he/it) → DOES

More clearly, the conjugation of the verb to do is presented in the table.

Consider a few sentences with the verb do:

I do teaching for a living. (I make a living teaching.)

We do our job with pleasure. (We enjoy doing our job.)

You do the same thing every week. Why? (You do the same thing every week. Why?)

They do a lot of different things in their free time. (They do many different things in their free time.)

And sentences with the verb does:

He does exercise every morning. (He exercises every morning.)

She does her shopping every Wednesday. (She does shopping every Wednesday.)

We have a multi cooker. It does most of the cooking for us. (We have a slow cooker. She mostly prepares food for us.)

In general, this rule does not contradict the basic way of conjugation of verbs in English. Usually we add to the verb in the third person singular Present Simple - s.

I sit - He sit s (I'm sitting - He's sitting)

We live in Moscow - She live s in New York. (We live in Moscow - She lives in New York)

The same thing happens with do, only we add - es: I do-He do es .
According to the same model, the corresponding form of the verb to go is formed (I go - He go es ).

Naturally, as a subject there are not only pronouns (I / you / he, etc.), but also nouns (both proper and common nouns). If in doubt, mentally replace the noun with a pronoun.

Mary does the cooking (Mary cooks food). She does the cooking (She cooks food).

Mary and Kate do the shopping together (Mary and Kate go shopping together). They do the shopping together (They go shopping together).

Zoe likes to sing . She does it whenever she can. (Zoe loves to sing. She does it when she can)

Peter and Jack clean their room on Fridays . They do it every week. (Peter and Jack clean the room on Fridays. They do it every week).

Why is it important to learn verb conjugations? to do?

The verb to do is a meaningful verb. It will be easier for you to move forward in learning English if, after the first meeting with the verb do, you learn (or remember) its conjugation in the present simple.

• act as a semantic verb
  In principle, we have already seen in the examples above do as a semantic verb (i.e. the verb on which the main meaning of the sentence lies). Here are a few more examples:

Could you do me a favor please? (Please do me a favor).

He does his homework every day. (Jy does his homework every day.)

In my family my mother does the cleaning. (In my family, my mother does the cleaning.)

• be an auxiliary verb(to form an interrogative or negative sentence)

An auxiliary verb is a verb that does not carry a semantic load, but is needed to build a grammatically correct construction.

In English, in Present Simple (and Past Simple), a general question (i.e., a question to which the answer is yes or no), as well as a negative sentence, are formed using the verb to do.

Question = do/does+subject + predicate (semantic verb)
Do they work hard? – Yes, they do. (Do they work a lot? - Yes.)

Do I know him? -

Does he watch TV every night? - No, he doesn't. (Does he watch TV every evening? - No.)

Does Mary eat apples? (Mary eats apples?)
The choice of the form of the verb, do or does, depends on the subject: with I, We, You, They - DO,

with He, She, It - DOES

Negation = subject + do not (don't)/does not (doesn't) + predicate (semantic verb)
I do not(don't) eat cakes. (I don't eat cake).

We don't like this film. (We didn't like this movie).

Peter and Mary don't want to go there. (Peter and Mary don't want to go there).

She doesn't playing tennis. (She doesn't play tennis).

Peter doesn't live in Paris. (Peter does not live in Paris).

The choice of the form of the verb, do or does, also depends on the subject: with I, We, You, They - DO NOT (DON'T), with He, She, It - DOES (DOESN'T)

*Don't / doesn't - abbreviated forms of do not / does not used in informal correspondence, as well as in the transmission of colloquial speech.

NB: Pay attention to the cases when the verb do acts both as a semantic and as an auxiliary.
I don’ t do it. (I am this not do).

He doesn't’ t do it. (I am this not does).
The underlined verb is an auxiliary (thanks to it, we formed a negative

sentence), highlighted in bold - semantic. If in question or negation in
do is used as a semantic verb, it always stands in the form do.

Wed I don't do it. (I am this not do).
I don’ t like it. (I am this not I love).

She doesn't do the shopping. (She not does purchases).

It doesn't do him credit. (This not does honor to him).

The situation is similar with interrogative sentences.

What do you do? (What do you do? / What do you do?)

What does he do? (What does he do?)

3) serve as a verb – substitute
To avoid tautology, the verb mentioned in the previous sentence can be

replace with the verb do.

Jane eats apples. She does it every day. (Jane is eating apples. She does it's every day).

They work at hospital. They do it for free. (They work in hospital. They do it

4) underline or highlight what action

In some cases, you need to highlight the meaning of the verb. Sometimes this is done with the verb do. The rule of using do and does in this case remains the same, but the semantic verb does not change.

They do want to help you. (They really want can I help you).

He does need this job. (Him desperately need this job).

The use of have has in English

So what's special about use of have has in English? First, it's important to pay attention to what the subject is in your sentence. It is from this moment that it depends which form of the verb you need to apply. According to the grammar rules has only friends with he, she, it; a have- with all other persons and numbers.



Secondly, do not forget that in addition to statements, there are also questions with negatives. Today it is permissible in negation to simply add not to the corresponding form of the verb to have, and for the question, put the same form in front of the subject who has something in your sentence. Also, you can ask for help from do and does. For negations with he, she, it fit doesn't, and for all others don't. Take out in the question do or does(for he, she, it) in front of the subject.

The use of have has in English

So what's special about use of have has in English? First, it's important to pay attention to what the subject is in your sentence. It is from this moment that it depends which form of the verb you need to apply. According to the grammar rules has only friends with he, she, it; a have- with all other persons and numbers.




Secondly, do not forget that in addition to statements, there are also questions with negatives. Today it is permissible in negation to simply add not to the corresponding form of the verb to have, and for the question, put the same form in front of the subject who has something in your sentence. Also, you can ask for help from do and does. For negations with he, she, it fit doesn't, and for all others don't. Take out in the question do or does(for he, she, it) in front of the subject.

In other words, the use have has in English is practically no different from other verbs in the present tense. It is only important to remember that there is a form has.

The use of have in English with examples

Like all the other rules use of have in English Better to remember with examples. This is what we will do right now!

example	translation
(+) We have two cars in the garage.	We have two cars in the garage.
(-) We haven't two cars in the garage. We don't have two cars in the garage.	We don't have two cars in the garage.
(?) have you a car in the garage? Do you have a car in the garage?	Do you have a car in the garage?
(+) He has five dogs at home.	He has five dogs at home.
(-) He hasnt dogs at home. He doesn't have dogs at home.	He has no dogs at home.

To have is one of the most frequently used verbs in the English language, and, unfortunately, is used incorrectly in many cases.

This verb appears at all levels, but in textbooks information is given separately, and the features of the verb to have are almost never understood in detail and systematized.
Therefore, ideas about the verb to have are ambiguous: many believe that this is a very unusual verb, it has some special forms, questions and negations, whether it is semantic or auxiliary, has different meanings, then it is translated, then it is not ...

Indeed, the verb to have is endowed with a mass of meanings (which we will soon consider in this article), so it can be translated in different ways. It is true that it can be both semantic and auxiliary (more on that later).

But its forms are very simple: there are only three of them. In the present tense, have has two forms: have for (I, you, we, they) and has for (he, she, it).

I do not have a yacht. - I don't have a yacht.
He does not have a girlfriend. - He doesn't have a girlfriend.
You didn't have much money. - You didn't have much money.

And now attention: typical mistake. In short answers to general questions, we do not use have, but the auxiliary verb of the time in which the question is asked:

Do you have a yacht? - Yes, I do./No, I don't. (So ​​wrong: Yes, I have./No, I haven't.)
Does he have a girlfriend? - Yes, he does./No, he doesn't. (So ​​wrong: Yes, he has./No, I hasn't.)
Did you have much money? - Yes, we did./No, we didn't. (So ​​wrong: Yes, I had./No, I hadn't.)

2. Relationship.

When we talk about people: about our family or loved ones, then this is more of an attitude than a possession, do you agree? Although the translation would be the same as in the first meaning: "someone (has) someone":

I have two sisters. - I have two sisters.
We have a lot of friends. We (have) many friends.
They have a big family. - They (have) a big family.

Again I emphasize that, speaking in the first two meanings, the verb have is state verb (State Verb). This means that he can not be used at times Continuous groups. We cannot observe action as such. It would be wrong to say: I am having a car or she is having a brother. Remember that in the meaning of "I have" - ​​only I have .

Second important point . The verb have in meanings own, possess, have in colloquial speech is often replaced by the form have got. About the differences have and have got we will talk in a separate article, which will appear on the blog very soon due to numerous requests from our subscribers. I encourage you to check it out, stay tuned!

3. Actions.

Do you know why there are so many set expressions with the verb have?
The fact is that in addition to its basic meanings described above, it can also replace other verbs, and therefore it has “taken root” in speech in these combinations. Consider examples of expressions in which have - does not mean “to have, own, possess”, but replaces another action:

Have in meaning eat (eat) :

Have breakfast/lunch/dinner - have breakfast, lunch, dinner
have a sandwich for breakfast - have a sandwich for breakfast
I will have a salad and some chicken, please. - I will (eat) salad and chicken, please.
What do you have for dinner? - What do you eat for dinner?
He is having his breakfast now. - He's having breakfast now.

Have in meaning drink (to drink) :

Have some coffee / some tea - drink coffee, tea
have a glass of wine - drink a glass of wine
I will have a cup of green tea. - I will (drink) a cup of green tea.
You should have some water if you are hot. - You should drink water if you are hot.

Have in meaning suffer from(suffer from) or experience(experience, experience)

Have a headache - suffer from a headache
have a cold - suffer from a cold
have a cough - suffer from a cough
I am having a terrible toothache! - I have a terrible toothache!
have an accident - survive an accident
have a difficulty - experience difficulties

Have in meaning give birth to(beget):

Have a baby - give birth to a child
She is going to have a baby. - She's going to have a baby.
They want to have three children. - They want to have three children.
Our dog had four puppies. - Our dog gave birth to four puppies.

Have in meaning get(receive, buy):

Have news - get news
have information - get information
have a hometask - get homework
I must have those new shoes! - I have to buy those new shoes!

Have combined with a noun conveys a single short-term action, the meaning of which depends on the noun. It's not hard, see:

Have a walk - take a walk
have a look - look
have a bath / shower - swim
have a talk - talk
have a conversation - talk
have a drink - drink
have a swim - swim
have a ride - ride
have a nap - take a nap

In the above expressions, we have, we mean another verb that is an action verb, so changing the meaning from state to action, the verb have can be used in Continuous group times. What you, by the way, could notice in some examples.

4. Have to - the equivalent of the modal verb must.

If after the verb have there is an infinitive with a particle to, then before you is the equivalent of the modal verb must(should, must). The fact is that must has no forms of past and future tenses.
But after all, we need to talk about obligations not only in the present, but also in the past and in the future tense. And this is where have to comes to the rescue.

It is important to remember that despite the connection with the modal verb and the unusual form, in this sense the verb have continues to be semantic, so it forms negations and questions with the help of the auxiliary verb of the tense you need:

I do not have to work tomorrow. - I don't have to work tomorrow.
We did not have to buy flowers. We didn't have to buy flowers.
He won't have to do much work. He won't have to do a lot of work.
Does she have to pay? - Does she have to pay?
Did you have to cook? - Did you have to cook?

You can learn more about this meaning of the verb have, its use and differences from must.

5. Auxiliary verb in Perfect tenses.

Have in combination with the third form of verbs forms perfect forms. Depending on the time, the form of the verb have, and the third form remains unchanged: in the present tense forms are used (have and has), in the past (had), and in - will have.
You can read in detail about each of these times in the articles devoted to them, but now I would like to clarify the issue of. In the examples that we analyzed above, it was unacceptable to abbreviate the verb have (although sometimes you want to). In the tenses of the Perfect group, since have is an auxiliary verb, it can be abbreviated:

I have - I've - / aɪv /
you have - you've - /juːv/
we have - we've - /wiːv/
they have - they've - /ðeɪv/

He has -he's - /hiːz/
she has - she's - /ʃiːz/
