Demonstrative Adjectives
We use demonstrative adjectives to talk about specific examples of a noun. These are a kind of determiner.
The demonstrative adjectives are:
- this
- that
- these
- those
Although these look exactly like the demonstrative pronouns, when placed in front of a noun they function as demonstrative adjectives.
Usage
We use them to talk about whether a noun is singular or plural, near or far.
| singular | plural | |
| near | this | these |
| far | that | those |
When we talk about a singular or non-countable noun, we use this if the noun is close to us (in space or time), or that if the noun is far away (in space or time):

Usage vs Speaker
Which word you use will depend on the speaker, who must use their own frame of reference. In this example the noun being talked about is the same but the two speakers use a different demonstrative adjective because one is close whilst the other is distant:
