Adjectives in Russian

An adjective's ending always matches the gender of the object they describe:

masculinefeminine neuterplural
-ый*-ая -ое-ые
вкусный супtasty soup вкусная курицаtasty chicken вкусное мясоtasty meat вкусные тортыtasty cakes

*Masculine nouns can also have other ending such as -ой and -ий; -ый is most common.

There are also soft adjectives, whose masculine forms end in -ний. These simply use soft vowels (я, е, и, ю) in place of hard ones (а, о, ы, у) in every grammatical case.

masculinefeminine neuterplural
-ий-яя -ее-ие
средний ребёнокmiddle child средняя школаmiddle school среднее имя*middle name
*имя is an irregular noun- it appears feminine but is neuter.
средние сиденьяmiddle seats

Adjectives can be shortened for simple, subject-adjective sentences (for example: that building is old; this woman is kind; my dog is cute).

Like nouns and pronouns, adjectives change with grammatical case. These are in their nominative forms.

Comparative adjectives

There are a few way to compare nouns using adjectives.

Using более more / менее less + чем than

Этот суп менее вкусный, чем тот.This soup is less tasty than that one.

Ее картина более красивая, чем его скульптура.Her painting is more beautiful than his sculpture.

As you can see, the adjective still matches the gender of the noun.

Using the ending ее + чем

Тот суп вкуснее, чем этот.That soup is tastier than this one.

Notice the pronouns are switched- this ending always means more.

Ее картина красивее, чем его скульптура.Her painting is more beautiful than his sculpture.

Many adjectives undergo consonant mutation using this ending.

Using the genitive case in place of чем

Этот суп менее вкусный того.This soup is less tasty than that one.

Ее картина красивее его скульптуры.Her painting is more beautiful than his sculpture.

The adjective самый means (the) most. It can be used with other adjectives, with both matching the gender of the noun:

самый молодой сынyoungest son самая большая собакаbiggest dog само66е маленькое яйцоsmallest egg самые старые девушкиoldest girls
