The genitive is the most difficult case and the most common - you meet it in nearly every sentence. Its most fundamental meaning is possession, the English “of” or apostrophe-s, and Russian expresses it purely by changing the noun’s ending, with no preposition needed.
The core idea: “of”
English shows possession two ways: friend’s car (apostrophe-s) or car of the friend (preposition). Russian does neither - it just puts the possessor in the genitive: машина друга (literally “car of-friend”, where друга already means “of friend”).
The word order matters: the possessor comes after the thing possessed. “This is Michael’s car” is Это машина Майкла (car of Michael), never Это Майкла машина.
A useful hint: whenever English would say or imply “of”, Russian tends to use the genitive.
Singular endings
Masculine and neuter take -а / -я; feminine takes -ы / -и. The soft variants (-я, -и) keep a soft consonant soft, and -и also appears after the seven consonants г к х ж ч ш щ.
| Gender | Nominative | Genitive | Meaning |
|---|---|---|---|
| Masc | друг | друга | of a friend |
| Masc | брат | брата | of a brother |
| Masc (inanimate) | дом | дома | of the house |
| Masc (soft) | отель | отеля | of the hotel |
| Masc (-й) | чай | чая | of tea |
| Neut | молоко | молока | of milk |
| Fem | сестра | сестры | of a sister |
| Fem | мама | мамы | of mum |
| Fem (inanimate) | машина | машины | of the car |
| Fem (soft) | тётя | тёти | of an aunt |
| Fem (soft) | кровать | кровати | of the bed |
| Fem (7-cons) | книга | книги | of the book |
Note the feminine genitive singular looks identical to the nominative plural (машины) - a coincidence of endings, not the same form.
Names
Names with a clear gender ending decline: Александр → Александра, Сергей → Сергея, Анна → Анны, Мария → Марии, Наташа → Наташи. Names without a clear Russian gender ending do not change: Это машина Мэтью (Matthew’s car), Это машина Меган (Megan’s car). Shorten them and they can decline: Мэтт → Мэтта.
Beyond possession
The dedicated lesson focuses on possession and the endings, but the genitive has several other everyday uses (from the overview):
- Absence - нет + genitive, in all tenses: У меня нет денег (I have no money), не было, не будет.
- Quantity - after много, мало, несколько, and numbers from five up: много времени (a lot of time).
- Comparison - больше времени (more time), меньше времени (less time).
- After prepositions - без (without), для (for), около (around/near), из (from), от (from), до (until), после (after), у (at/by).
Lessons worth keeping
- Genitive is everywhere and means “of”: possession, absence, quantity. When English implies “of”, reach for genitive.
- Endings: masculine/neuter -а/-я, feminine -ы/-и (soft-stem and post-г/к/х/ж/ч/ш/щ take the soft/-и variant).
- Word order: possessor after the possessed (машина брата, not брата машина).
- Absence uses нет + genitive across past, present, and future; quantity words and numbers 5+ trigger it too.
- Names that lack a clear gender ending stay unchanged even in the genitive.
