Short-Form Adjectives in Russian

Overview

Russian adjectives have two forms: the long (full) form used attributively and predicatively, and the short form used only predicatively (as the complement of a sentence). At the A1 level, short-form adjectives are important because several very common words -- должен (must), рад (glad), готов (ready), занят (busy) -- exist primarily or exclusively in short form.

Short-form adjectives agree with the subject in gender and number but not in case (since they are always predicative). They tend to express temporary states, specific situations, or categorical judgments, while long-form predicative adjectives describe more permanent or general characteristics. However, at the beginner level, the practical priority is simply recognizing and using the most common short forms.

The formation is simple: remove the long-form ending and add the short-form ending (or no ending for masculine). The main challenge is that some short forms have stress shifts or vowel insertions that must be memorized.

How It Works

Short-Form Endings

Gender/Number	Long Form	Short Form
Masculine	-ый/-ий/-ой	(no ending)

Plural	-ые/-ие	-ы/-и

Common Mistakes

Using long form where short is required

• Wrong: Он должный работать.
• Right: Он должен работать.
• Why: Должен, рад, and several others exist almost exclusively in short form.

Forgetting gender agreement in short forms

• Wrong: Она готов. (masculine form with feminine subject)
• Right: Она готова.
• Why: Short-form adjectives agree in gender with the subject, even though they have no case.

Incorrect stress on feminine forms

• Wrong: Stressing за́нята instead of занята́
• Right: Many feminine short forms shift stress to the final syllable: занята́, права́, важна́
• Why: Stress shifts in feminine short forms are common and must be memorized.

Practice Tips

• Drill the most common short-form adjectives (должен, рад, готов, занят) across all genders: он должен, она должна, оно должно, они должны.
• Practice expressing obligations and states using short forms in daily conversation: Я готов, Она занята, Мы должны идти.
