Adjectives

They agree with their noun in gender, number and case — twenty-four forms, though many are identical.

-ого is said /əvə/. That г is a /v/ in every one of these endings.

The masculine accusative depends on animacy — see Nouns & gender.

Short forms

Many adjectives have a second, shorter set used only as a predicate:

Он бо́лен. — He is ill. (not больно́й, which suggests a chronic condition)

Short forms carry a temporary state; long forms a permanent quality. Он злой is a nasty man; он зол is a man who is currently angry.

Comparison

• -ее: но́вый → нове́е
• irregular: хоро́ший → лу́чше, плохо́й → ху́же, большо́й → бо́льше

Than is either чем or the genitive on its own:

• Он вы́ше, чем я.
• Он вы́ше меня́. — "taller of me"

Superlative: са́мый in front, agreeing — са́мый но́вый.

Adverbs

Take the neuter short form: хоро́ший → хорошо́, бы́стрый → бы́стро. That is also why so many impersonal expressions look like neuter adjectives — хо́лодно, жа́рко, ску́чно — because that is exactly what they are.
