Adjective Agreement in the Nominative Case

1. The Golden Rule: Adjective-Noun Agreement

In Russian, adjectives are not one-size-fits-all. They must "agree" with the noun they describe in three ways: gender, number, and case.

For today, we are only focusing on the nominative case, which is the case for the subject of a sentence. Think of it this way: the noun is the "boss," and the adjective must change its ending to match the noun's gender (masculine, feminine, neuter) and number (singular, plural).

Let's begin with a video that breaks down these changes clearly.

The key idea is that we look at the last two letters of the adjective to determine its form. Let's see how this works for each gender.

2. Adjective Endings: Gender and Number

We'll continue with the same video, breaking it down by gender. As you watch, pay attention to the example phrases, especially those that relate to your interests, like интересный сериал (interesting series) or новые друзья (new friends).

Masculine Adjectives (Мужско́й род)

The masculine singular form is the "dictionary form" of an adjective. It most often ends in -ый or -ий. A small group of adjectives have a stressed ending -ой.

Examples:

• но́в**ый** фильм (a new film)
• хоро́ш**ий** вопро́с (a good question)
• больш**о́й** успе́х (a big success)

Feminine Adjectives (Же́нский род)

Feminine adjectives are easy to spot: they almost always end in -ая.

Examples:

• но́в**ая** рабо́та (a new job)
• интере́сн**ая** исто́рия (an interesting story)
• больш**а́я** соба́ка (a big dog)

Neuter Adjectives (Сре́дний род)

Neuter adjectives typically end in -ое.

Examples:

• но́в**ое** зда́ние (a new building)
• интере́сн**ое** интервь́ю (an interesting interview)
• хоро́ш**ее** настрое́ние (a good mood)

Plural Adjectives (Мно́жественное число́)

Finally, for plural nouns of any gender, adjectives end in -ые or -ие.

Examples:

• но́в**ые** друзья́ (new friends)
• интере́сн**ые** иде́и (interesting ideas)
• хоро́ш**ие** но́вости (good news)

3. Understanding the Rules: Hard, Soft, and Spelling

You may have noticed that there are sometimes two possible endings (e.g., -ый or -ий for masculine). The choice depends on the last consonant of the adjective's "stem" (the part before the ending). While this might seem complex, it follows a few predictable rules, much like reaction rules in chemistry.

This article from Mango Languages has a fantastic table that organizes these rules clearly.

Here is a visual summary of those rules, which can be a great reference.

The main takeaway is the 7-letter spelling rule: After the consonants г, к, х, ж, ч, ш, щ, you cannot write the letter ы. You must write и instead. This is why we have хороший (not хорошый) and хорошие (not хорошые).

4. Practice

Let's try putting this into practice. For each pair, change the adjective in parentheses to agree with the noun.

1. (но́вый) + компью́тер (m.) → ?
2. (интере́сная) + кни́га (f.) → ?
3. (хоро́шее) + кино́ (n.) → ?
4. (но́вые) + видеои́гры (pl.) → ?
5. (большо́й) + дом (m.) → ?
6. (ма́ленькая) + иллюстра́ция (f.) → ?

Excellent! You're now able to describe nouns using adjectives.

Conclusion

In this lesson, you've learned one of the most fundamental rules of Russian grammar.

Key Takeaways:

• Adjectives must agree with nouns in gender and number (and case).
• The basic endings in the nominative case are:
  • Masculine: -ый, -ий, -ой
  • Feminine: -ая, -яя
  • Neuter: -ое, -ее
  • Plural: -ые, -ие
• The choice between endings like -ый/-ий depends on spelling rules related to the adjective's stem.

Preview of the next lesson:
Now that you can make adjectives agree in the nominative case (e.g., Э́то интере́сная кни́га), the next logical step is to use them as direct objects. In the next lesson, we will learn how to match adjective endings to noun gender in the accusative case, so you can say "I am reading an interesting book" (Я чита́ю интере́сн**ую** кни́г**у**).
