Demonstrative Adjectives

Just like the Demonstrative Pronouns we learned earlier, Demonstrative Adjectives use the exact same four basic words: this, that, these, and those.

Their main purpose is also the same: to indicate the distance (near/far) and quantity (singular/plural) of a noun.

So, what is the difference? The difference lies in their position and how they function in a sentence.

Basic Rules for Demonstrative Adjectives

A word is called a Demonstrative Adjective if it is placed directly in front of the noun it is pointing to.

Remember the basic function of adjectives: their job is to modify (describe) a noun. Therefore, these adjectives cannot stand alone!

DistanceSingular (1)Plural (>1)
NearThis + Singular nounThese + Plural noun
FarThat + Singular nounThose + Plural noun

1. This (Singular / Near)

  • This book is very interesting. (The word this is directly attached to book).
  • I like this city.

2. These (Plural / Near)

  • These apples are sweet. (The word these is directly attached to the plural noun apples).
  • Can you help me carry these boxes?

3. That (Singular / Far)

  • That car belongs to my uncle.
  • Look at that bird!

4. Those (Plural / Far)

  • Those children are playing in the park.
  • I want to buy those shoes.

Comparison: Adjectives vs Pronouns

This is the most common mistake made by beginners. Let’s compare them directly so you won’t be confused anymore:

Case 1: Using This

  • This is a delicious cake. (Demonstrative Pronoun).
    Why? Because this stands alone and is followed by the verb is. It completely replaces the noun.
  • This cake is delicious. (Demonstrative Adjective).
    Why? Because this is directly attached to the noun cake to describe it.

Case 2: Using Those

  • Are those your friends? (Demonstrative Pronoun).
    Why? It stands alone after the helping verb are.
  • Are those boys your friends? (Demonstrative Adjective).
    Why? It is attached directly in front of the noun boys.

Conclusion: If there is a noun directly after the pointing word, then it is a Demonstrative Adjective. If the pointing word stands alone, then it is a Demonstrative Pronoun.
