That is plural in English. How to use this, that, these, those, it, there

This, that, these, those are demonstrative or demonstrative pronouns in English. As a rule, this, that, these and those are used to indicate a specific object, creature or phenomenon. When should you use these pronouns? What is their difference? Read more in the article.

Basic Rules

So, the rule about this, that, these and those indicates: in English speech these words can serve not only as pronouns, but also as determiners. Consider the following table.

It's also worth noting that these is the plural form of this, and those is the plural form of that.

Thus, this and that should be used with singular nouns, and these and those should be used with plural nouns.

Using the pronouns this, that, these and those: rule

The first thing to remember is that we use this and that with uncountable nouns as well as singular nouns.

Try to repeat this exercise every morning and evening.
What does this music make you think.
I’ve never been to that part of France.
Can I have some of that juice, please?
  • Try to repeat this exercise every morning and evening.
  • What does this music make you think about?
  • I've never been to this part of France.
  • Can I have some of this juice please?

The English rule about this, that, these and those indicates that these and those should be used exclusively with plural nouns:

You can use any one of these computers.
I need to paint those windows.
  • You can use any of these computers.
  • I need to paint those windows.

Interestingly, according to the rules of the English language, this, that, these and those are used in the context of time.

Demonstrative pronouns and tenses

For example, we often use this with words that describe time and date (morning, afternoon, evening, week, month, year).


In this case, it is important to refer to the time in which the speaker directly speaks, or the time that is coming. For example:

I'll be with you some time this evening.
Johan seemed very happy this afternoon.
Ian is in Germany all this week.
  • I'll be with you tonight.
  • Johan seemed very happy this afternoon.
  • Jan is in Germany this week.

This, that, these, those are the rules for using as pronouns further.

This, that, these, those - pronouns

We use the above words as pronouns when referring to things or phenomena:

Put the butter, chocolate and sugar in a saucepan. Heat this over a low flame until it melts.

Add the butter, chocolate and sugar to the pan. Heat it (this/container with the mixture) over low heat until the ingredients melt.

What color are those? Black or dark blue. I can't see.

What color are they? Black or blue. I can `t get it.


It is acceptable to use this and that if you want to refer to a person:

Linda, this is my mother, Anne.
Is that your brother over there?
  • Linda, this is my mother, Ann.
  • Is that your brother there?

Demonstrative pronouns are often used in telephone conversations.

Hello, is that Ken Orm? This is Jane Bromham here.

Hello, is this Ken Orme? This is Jane Bromham calling.

Use cases of this and these, that and those

In many ways, the selection of the correct pronoun is determined by the physical proximity of the object/person/phenomenon to the speaker. Those and these, this, that and the writing rules are presented in the following examples:

Translation: Should I use this knife?

I'll post these letters on my way home.

Translation: I will send these letters on the way home.

We use that and those to refer to things and people that are not easily identified in a particular situation.


They are often further away from the speaker, and sometimes closer to the listener:

What's in that bottle over there?
Could you blow out those candles near you?
  • What's in that bottle over there?
  • Can you blow out those candles next to you?

Sometimes they are not in the field of view of either the listener or the speaker:

Budapest! That's my favorite place!

Translation: Budapest! My favorite place!

Emotional meaning

Oddly enough, in the rule about this, that, those and these and the use of these pronouns, the speaker’s attitude towards them plays an important role. So, we use this and these when thinking about positive things that we like to think about.

I love these new blue walls.

We use that and those to point out things that don't make us feel good.

(talking about the restaurant) I didn’t like the decoration. It had those awful paintings.

I didn't like the decor. There (in the restaurant) these terrible pictures hung.

Generally known information

We sometimes use that instead of the to direct the listener to commonly known information. For example, when telling a story or explaining something, we might say:

Do you know that old shop on the corner? Well, they’re going to turn it into a restaurant.

You know that old corner store? Basically, they're going to turn it into a restaurant.


It is also acceptable to use this instead of the indefinite article a/an if the speaker is referring to something important or relevant, or is going to introduce a new person or mention something new.

This guy knocked on the door and asked if I wanted new windows.
Then suddenly she pulled out this big pile of papers from her briefcase and threw them on the table.
  • This guy knocked on the door and asked if I wanted new windows.
  • Suddenly she pulled out such a large pile of papers from her pocket and threw it on the table.

What other uses of this, that, those, these are there?

Replacement

In the context of formal speech, it is acceptable to use the demonstrative pronouns that and those as substitutes in the meaning of the one(s), in order to avoid lexical repetitions.

The most important information is that given at the beginning of the manual.

The most important information is that given at the beginning of the manual.

In this case, that replaces the word information.

The methods employed are those familiar to researchers. (sounds more formal than The methods employed are the ones familiar to researchers.)

The methods used are those(methods) that are familiar to the researchers.

In the context of formal writing and speech, especially in academic style, we use that of/those of instead of the one of/the ones of. The use of demonstrative pronouns in this case is preferable.

The proton has a similar mass to that of a neutron

A proton has a mass similar to the mass of a neutron. In this case we can see that the word mass has been replaced by the construction that of.

The emotions in the poems are those of loss and grief.

Translation: The emotions in the poems are those of loss and grief.

It should be noted that in English the demonstrative pronoun that can only be used as a substitute for a thing or object. This pronoun is not used in relation to animals, people and other living beings. Consider the following dialogue.

B: The one who works at the town hall, or his brother?
You can't say: That who works at the town hall.

A: Have you met Mr. Kelly?

Q: The one who works at the town hall, or his brother?

A: The one who works at the town hall.

However, the use of this plural demonstrative pronoun as a substitute for people and animals is permitted. For example:

There are sports facilities for guests.Those interested in golf can enjoy our course.

There are sports facilities for guests. Those who are interested in golf can enjoy our course.

Demonstrative pronouns in English ( demonstrative pronouns / demonstratives) indicate a person, object, or their signs. There are several demonstrative pronouns in English.

Singular Plural
this– this, this, this these- these
that- that, that, that those– those
such- such, similar such- such, similar
the same- the same the same- same
it- This it- This

Now you know what demonstrative pronouns are in English. Next we will look at cases where each of them is used.

Demonstrative pronouns this and these

This these– with plural nouns. These pronouns should be used in the following cases:

  1. When we talk about people or things that are close to us. Sometimes in sentences with this And these adverb is used here(here), which also shows the proximity of the object to us.
  2. This table is wooden. – This table wood. (the table is nearby and we point to it)

    These books belong to me. – These books belong to me. (several books are near me)

    This girl is here and she is waiting for you. – This girl Here, and she is waiting for you.

  3. When a situation occurs in the present or future tense, we describe this situation using this/these.
  4. We are going to meet this week. - We are going to meet at this week.

    This month you are making a great progress. - IN this month you are making great progress.

  5. When we talk about the same thing several times and want to avoid repetition.
  6. I don't want to discuss this but I have to. - I don't want This discuss, but I have to. (implies that this event has already been called before, thus avoiding repetition)

    Look at this! He seems to be looking for his money. - Look at This! Looks like he's looking for his money. (the pronoun indicates the situation described in the second sentence)

    This is the main goal in my life. – This main goal in my life.

  7. When we introduce people or introduce ourselves in a telephone conversation.
  8. Jim, these are my brothers, Tom and Carl. – Jim This my brothers, Tom and Carl.

    Hello! This is Kate speaking! Can I speak to Mary? - Hello. This Kate. Can I talk to Mary?

Demonstrative pronouns that and those

Demonstrative pronoun that used with singular nouns, pronoun those– with plural nouns. Let's see when we can use demonstrative pronouns that And those:

  1. When we talk about people or things located far away from us. Sometimes in sentences with demonstrative pronouns that And those adverb used there(there).
  2. I don't like this piece of cake. Give me that one, please. – I don’t like this piece of cake. Give me That, Please. (the piece of cake that the speaker liked is located further from him)

    Those ships are too far. I can't see their names. – Those ships too far. I don't see their names. (the indicated ships are at a distance from the speaker)

    Look at that! There's a camel. - Look there! Vaughn there camel.

    That's my future husband. – That- My future husband.

  3. When we talk about a situation that took place in the past.
  4. In those days people didn't have cars. - IN those times people didn't have cars.

    We made only four kilometers that day. - IN that day we only walked four kilometers.

  5. When we refer to some information that has been mentioned before and want to avoid repetition. We usually talk about a past action.

    She got married a month ago. That was wonderful! – She got married a month ago. It was Wonderful!

  6. When we start a conversation on the phone and ask the other person to introduce himself. The person on the other end of the line is far from us, so we need to use a demonstrative pronoun that.

    Good morning! This is Brenda White. Who's that speaking? - Good morning! This is Brenda White! Who am I talking to?

The picture clearly shows how demonstrative pronouns work this/that And these/those when indicating the proximity or distance of an object.

We also suggest you watch a video from the teacher Alex. It's interesting how a native speaker explains this topic.

Demonstrative pronouns such, the same, it

Other demonstrative pronouns in English include such(such, similar) the same(the same one) and it(This). Let's look at how they should be used in speech:

  1. When the noun is singular, then together with the demonstrative pronoun such(such, similar) the indefinite article is used.

    It's such an important decision - This such important decision.

    If the noun is plural, use the article after the pronoun such(such, similar) no.

    Don't do such things! - Don't do it such of things!

  2. Demonstrative pronoun the same(the same / the same) is always used with the definite article. Nouns after the same can be in either singular or plural form.
  3. Underline the word with the same meaning, please. – Please underline the word with same meaning.

    He chose the same movies as I did. - He chose the same films, and me too.

  4. Demonstrative pronoun it corresponds to the Russian pronoun “this”.
  5. – What is it? - What This?
    - It's my ring. - This is my ring.

    Is it your passport? – This your passport?

    Don't miss it! - Do not miss This!

Difference between this and it

Many linguists say that there is little difference between it And this No. You will be understood in any case if you say This is a cat or It is a cat. But there is a difference, albeit a small one.

This is a cat. - It's a cat. (we focus on the word “this”, that is, exactly this, and not that cat)

It is a cat. - It's a cat. (we focus on the word “cat”, that is, not a dog or a guinea pig)

And one last little detail. To avoid repeating the same noun twice, the word is sometimes used instead one. And before that one You must also use a demonstrative pronoun. If the demonstrative pronoun in English is not followed by an adjective, then one (ones) can be omitted.

Would you like to buy this hat or that (one)? – Would you like to buy this hat or that?

And if there is an adjective, then you must save it one or ones in a sentence.

I don't want to buy this hat, I will take that blue one. – I don’t want to buy this hat, I'll take it out that blue one

Greetings, everyone! Today we'll talk about the basics. We will tell you the difference between “this / that” and “these / those”, explain their meaning, give clear examples and decorate it all with a final table with the difference.

It's time to clear your doubts and learn the difference so you can be 200% confident in using some of the most common words in the English language.

This and That

The main difference is distance of the object from the speaker.

You need to use " this"[ðɪs] - this / this / this, when the object is close to the speaker (he is holding it in his hands, for example), and " that» [ðæt] - that / that / that when it is at a distance or outside the field of view of the speaker or listener.

This is my cat (pointing at a cat on my lap).
This my cat (pointing to him on her lap).
That is his dog (pointing at a dog beside some stranger on the street).
Ta his dog (pointing to the dog next to the stranger on the street).

Note that tense will also affect the use of "this" and "that" as demonstrative pronouns.

If something happened in the past, use " that" would be more appropriate. Although in Russian we still say “this”.

You can, of course, say “that”, but it will sound suspiciously strange. There is no need for clarification, which cannot be said about English.

He didn't die yet. That made me think.
He's not dead yet. This got me thinking.

On the other hand, if the event has not yet occurred, then the appropriate form would be " this».

She won't go to church tomorrow. This is quite strange.
She won't go to church tomorrow. This quite strange.

It’s surprising that Americans, when they pick up the phone, usually say: “ Who is this?", and the British - " Who is that?».

Usually we use " that", speaking about things, but not about people or animals:

Right: - Have you met Mr. Rogers? - The one with the stupid haircut or silly mustache?
Wrong: That who has stupid haircut?

These and Those

In a formal context, especially in scientific work, when talking about the similarity of something, we use " that of / those of" instead of "the one of / the ones of".

The proton has a similar mass to that of a neutron.
A proton has a similar mass to the proton of a neutron.
The emotions in the poems are those of loss and grief.
The emotions in the poems reflect loss and grief.

How to use these pronouns

  • In the role defining word:
What's in this bag?
That whiskey tastes strange.
I might get myself a pair of those Nikes.
  • In the role pronouns(meaning things or ideas):
Come and look at this.
That's a very bad idea.
Can I have one of these?


Uses of this and that

Emotional distance

Sometimes we use this, that, these and those to refer to things that make us happy.

For example, you can use " this/these”, referring to something we approve of or feel positive about.

I love this new woolen smartphone cover that you can get.
I like this new wool phone case, which you can get.

We use " that/those” to create distance.

What are you going to say to that friend of yours?
What are you going to say that friend of mine?

We use " those", talking about objects inside the room where we were.

I didn't like his house. It had those awful paintings.
I didn't like his house. It contained those terrible pictures.

Knowledge sharing and new information

Often this happens when we are telling a story or explaining something.

You know that waterfall in the forest nearby? Well, they're gonna privatize it.
You know That waterfall in the forest nearby? Well, they're going to privatize it.

« This" is sometimes used instead of "a/an" when we are referring to something important or recent, or when introducing someone to a new person or thing in our history.

This guy today knocked on the door and asked if I wanted to talk about God.
This the guy knocked on the door and asked if I wanted to talk about God.

Physical proximity and distance

We use " this", And " these» most often, pointing to things and people that are close to the speaker or writer, or to what is happening at the moment.

Shall I use this knife here?
I should take advantage this with a knife?
I'll post these letters on my way home.
I'll throw it in these letters to the post office on the way home.

We use " that" And " those”, pointing out things and people that are not easily identified in a situation. They are often located at a distance from the speaker, and sometimes closer to the listener.

The Death Star! This my favorite star!

Demonstrative pronouns have separate forms for the singular - this this, this, this,
that mom, that, then- and plural - these these, those me.

Demonstrative pronouns are used both as adjective pronouns and noun pronouns.

1. Demonstrative pronoun-adjective, being a determiner of a noun,
excludes the use of an article before the noun to which it refers.
When the noun to which the demonstrative pronoun refers is preceded by others
definitions, then the demonstrative pronoun, like any determiner, is placed before them:

Don't live in that house. - He lives in that house.

He lives in that white house. - He lives in that white house.

2. Pronouns this And these indicate objects in
close proximity to the interlocutor, while that And those point to
more distant objects:

This pencil is mine. - This pencil is mine. (We are talking about a pencil that the speaker holds in his hand or that is directly in front of his eyes.)

That pencil is yours. - That pencil is yours. (We are talking about a pencil that is not in close proximity to the speaker.)

I like those flowers. - I like those (these) flowers. (We are talking about flowers that are not in close proximity to the speaker.)

3. Pronoun this with the word country used in relation to the country in which
there is a speaker or author. Therefore, when the combination country this found in
English newspaper, it should be translated England, in an American newspaper - USA, V
message from a correspondent from Holland - Holland etc.:
The exports of coal from this country decreased last year (from an article in an English newspaper). Coal exports from England fell last year.

The exports of coal from this country decreased last year (from an article in an English newspaper). - Coal exports from England decreased last year.

The imports of coal into this country decreased last year (from a report by a correspondent from Holland, published in an English newspaper). - Coal imports to Holland decreased last year.

If we are not talking about the country of residence of the speaker or author, then it is used that country
both with the meaning of that country and this country:

I was in Bulgaria last year. I liked that country very much. - I was in Bulgaria last year. I really liked this country.

4. This in time expressions refers to the moment of conversation or to the current period
time, a that- to a moment or period of time in the past or future:

I am busy at this moment. - I'm busy at the moment.

It is only the beginning of May. - It's only the beginning of May.

In Russian the demonstrative pronoun this (this) often used not only for
indications of nearby objects and to indicate the moment of conversation or the current period
time, but also to indicate more distant objects, objects that are not present,
and to indicate past and future moments or periods of time. Therefore the pronoun this (these)
in English in some cases it corresponds this (these), and in others that (those):
