In Russian, adjectives change to match the nouns they describe. This means they agree in three ways: gender, number, and case.

Let’s take the word "красивый," which means beautiful, and see how it fits with "дом," meaning house.

1. Gender:

• The word "дом" is masculine, so we use the masculine form of "красивый."
  • Example: Красивый дом (beautiful house).

2. Number:

• If we are talking about one house, we say "красивый":
  • Example: Это красивый дом. (This is a beautiful house.)
• If we talk about more than one house, we change it to the plural form "красивые":
  • Example: Красивые дома (beautiful houses).

3. Case:

• In the nominative case (when we identify something), we say: Это красивый дом (This is a beautiful house).
• In the accusative case (when we talk about seeing something), the adjective changes to "красивого":
  • Example: Я вижу красивый дом (I see a beautiful house).

Practice Exercise:

Now, let's practice changing this sentence from singular to plural and then to the accusative case:

• Singular: Этот красивый дом.
• Plural: ____ (change this).
• Accusative: Я вижу ____ (use the plural form).
