Understanding how adjectives and nouns work together in Russian is really important for making correct sentences. Here’s what you need to know:

1. Noun Gender:

In Russian, nouns can be one of three types: masculine, feminine, or neuter. The gender affects how adjectives look.

• Masculine: For example, "большой" (big) + "стол" (table) = "большой стол" (big table).

• Feminine: "большая" (big) + "книга" (book) = "большая книга" (big book).

• Neuter: "большое" (big) + "окно" (window) = "большое окно" (big window).

2. Cases:

Adjectives also need to match nouns in gender and case. There are several cases, like nominative, accusative, genitive, dative, instrumental, and prepositional.

• Nominative: "красивый" (handsome) + "мальчик" (boy) = "красивый мальчик" (handsome boy).

• Genitive: "красивого" (handsome, in genitive) + "мальчика" = "красивого мальчика" (handsome boy in genitive).

3. Basic Sentence Structure:

In normal Russian sentences, adjectives usually come before the nouns.

• Example: "Красивый дом" means "Beautiful house".

4. Examples of Agreement:

When the gender or case of the noun changes, the adjective has to change too.

• Dative: "красивому" (beautiful, in dative) + "мальчику" means "to the beautiful boy".

• Accusative: "красивого" (beautiful, in accusative) + "мальчика" means "the beautiful boy".

Summary:

To sum it up, always make sure adjectives match nouns in gender and case.

Practice making sentences and pay attention to how adjectives change depending on the nouns they describe. This will help you speak and write in Russian more correctly!
