Demonstratives

this · that · these · those

What are demonstratives?

Demonstratives point to people, things, or places. They show distance (near or far) and number (singular or plural).

this
singular, near — this book (here, close to me)
that
singular, far — that book (there, away from me)
these
plural, near — these books (here)
those
plural, far — those books (there)

Near vs far

Distance from the speaker

Near (this/these)
This is my phone.
These are my keys.
Look at this photo!
Far (that/those)
That is your car.
Those are my friends.
Look at those birds!

Singular vs plural

Demonstratives MUST agree with the noun

Singular
this book / that book (one book)
Plural
these books / those books (more than one)
Uncountable
this water · that bread (always singular form)
Be careful! "this" and "these" sound similar but mean different numbers. Listen for the difference: this /ðɪs/ vs these /ðiːz/.

Two uses: adjective vs pronoun

Demonstratives can describe a noun OR replace it

As an adjective (+ noun)
This book is good.
These shoes are new.
As a pronoun (alone)
This is good.
These are new.

Phone, introductions, on the phone
