When it comes to discussing one’s distance from objects, things, or other people, it’s necessary to master the grammatical concept of demonstratives. To describe the physical distance of something or someone to another is a key aspect of demonstratives. Depending if the speaker is near or far from the other object, person, place or thing, the demonstrative will change to reflect that change in closeness.

A key aspect of demonstratives to remember is that they can either be adverbs or pronouns for both singular and plural nouns. You can use demonstratives as well to describe both countable and uncountable nouns. In addition, when it comes to discussing actual events, you would use ‘near’ forms of the demonstrative to refer to the present while ‘far’ forms of the demonstrative would refer to the past.

For the demonstrative adverbs, the word ‘here’ refers to the subject who is close by and near to the object, thing, or person. For the opposite, the adverb ‘there’ refers to the subject that is far away from the object, thing, or person.

Here are some examples of demonstrative adverbs for near / far usage:

I am here at the police station.
They are here for the Science exam.
She was there for the graduation ceremony.
We will be there at 9 o’clock.

Based on these examples, it’s important to remember that the adverb ‘here’ for near situations should be used in the present tense whereas for far situations, ‘there’ is heavily used and often with either the past or future tenses.

As mentioned before, if you are near to an object, thing, or person and you’re looking to use a demonstrative pronoun, you’ll want to use the words of ‘this’ or ‘these’ depending upon if its’ with a singular, uncountable noun or with plural, countable nouns. The demonstrative ‘this’ or ‘that’ would be used with singular and uncountable nouns while ‘these’ or ‘those’ would be used with plural and countable nouns.

Here are some examples of how ‘this’ and ‘these’ would be used in sentences to describe objects, things, or people that are close in distance to the subject:

This cup is for my tea.
Is this your jacket?
Where have you been traveling to these days?
These bananas are delicious.
This is my friend, Dan.

As you can see from these examples, these objects or things are close to the subject rather than far away in distance. You can also see how the demonstrative ‘this’ is used for singular nouns while the pronoun ‘these’ are being used with plural nouns.

If the opposite occurs and you or another subject in your sentence is far away in distance from another, person, place or thing, you’re going to want to use the demonstratives ‘that’ or ‘those.’

Here are some examples of how ‘that’ and ‘those’ would be used in sentences to describe objects, things, or people that are far in distance to the subject:

What are those men doing over there?
That book in my shelf was really enjoyable.
That printer has a paper jam that needs to be fixed.
Those boys are heading off to play in the park.
Those tires are flat. They need air.

It’s clear from those examples above that those objects or things are considered to be far away from the subject of the sentence. You can also see how the demonstrative ‘that’ is used for singular nouns while the pronoun ‘those’ are being used with plural nouns.

When it comes to placing a demonstrative like ‘that’, ‘this’, ‘these’, ‘those’ in a sentence, you should remember that those pronouns can be placed before the noun or adjective that modifies the noun even if there is more than one noun in the same sentence.

Examples:

Those hungry people need to eat soon.
These tired citizens are waiting long hours in the unemployment line.

Another way to use the demonstrative is that it can be placed before any number by itself when the noun is understood within the context of a larger paragraph.

Examples:

These four need to be fixed.
That one gave me some trouble.

Sometimes, a demonstrative pronoun or adverb can be used by itself in a sentence without a noun even being present after the demonstrative. The noun can be understood from the context of a previous sentence or larger paragraph making the demonstrative clear the only necessary subject to have.

Examples:

This was not very fair to me.
That is really cool.
Those were really interesting.
What was the issue with these?

As with many other grammatical concepts in English, there are some rules and circumstances that have to be remembered in order to develop both spoken and written fluency.
