Russian Noun Endings

Common endings by gender and case, singular forms

How the systems relate

Nouns

Decline by case

Change endings based on role in sentence. Gender and animacy live here.

Adjectives

Mirror the noun

Match the noun's case, gender, and number. The noun is the source of truth.

Verbs

Completely separate

Conjugate by person and number. No cases, no gender (except past tense). Aspect lives here only.


Accusative animate rule: For animate nouns (living things), accusative = genitive. For inanimate nouns, accusative = nominative. This applies across all genders. You only need to decide once per noun.
Masculine Ends in a consonant, -й, or -ь
Case Singular ending Example, солда́т (soldier)
Nominativesubject / dictionary form (none) солда́т
Accusativedirect object / target (none, inanim) -а (anim) солда́та
Genitiveof / belongs to / absence солда́та
Dativeto / for / recipient солда́ту
Instrumentalwith / by means of -ом -ем солда́том
Prepositionalabout / at / in (after prep) -и (soft) солда́те

Soft stem variant (e.g. учи́тель): -я / -ю / -е / -ем / -е follows the same pattern, just softened.

Feminine Ends in -а, -я, or -ь
Case Singular ending Example, ка́рта (map)
Nominativesubject / dictionary form ка́рта
Accusativedirect object / target ка́рту
Genitiveof / belongs to / absence ка́рты
Dativeto / for / recipient -и (soft/ь) ка́рте
Instrumentalwith / by means of -ой -ей ка́ртой
Prepositionalabout / at / in (after prep) -и (soft/ь) ка́рте

Feminine -ь nouns (e.g. ночь): genitive, dative, prepositional all take -и. Instrumental takes -ью.

Neuter Ends in -о or -е
Case Singular ending Example, сло́во (word)
Nominativesubject / dictionary form сло́во
Accusativedirect object / target -о / -е (= nominative always) сло́во
Genitiveof / belongs to / absence сло́ва
Dativeto / for / recipient сло́ву
Instrumentalwith / by means of -ом -ем сло́вом
Prepositionalabout / at / in (after prep) -и (soft) сло́ве

Neuter accusative always equals nominative, animate/inanimate distinction does not apply.


Patterns worth internalizing

Free endings

Neuter accusative = nominative always. Masc/neuter dative and genitive share the same vowel (-а/-у hard, -я/-ю soft). Less unique information than the tables suggest.

7-letter spelling rule

After г к х ж ш щ ч, write и not ы. Looks irregular, is actually phonetic. Affects genitive and plural frequently.

Hard vs soft stem

Hard stems take -а, -у, -ом, -е. Soft stems take -я, -ю, -ем, -е. Same pattern, just one step softer. The stem tells you which column to use.

Gender is the codebook

You don't memorize endings independently. You learn the gender once, then the ending is predictable. Gender = the key that unlocks the right row.

Adjectives follow nouns

Whatever case, gender, and number the noun takes, the adjective matches. The noun decides, adjective agrees. Aspect lives on verbs only -- nouns never have it.

Common irregular plurals

друг → друзья́, челове́к → лю́ди, ребёнок → де́ти. Small list, high frequency -- worth memorizing explicitly.
