Questions & Answers about Я купил костюм этого бренда.
Why is этого бренда in the genitive case here?
In Russian, to express “a suit of this brand,” you put бренд in the genitive to show possession. So этого бренда literally means “of this brand.”
What case is костюм in, and why does it look like the nominative form?
Костюм is the direct object of купил, so it should be in the accusative. For inanimate masculine nouns, the accusative singular is identical to the nominative singular. That’s why костюм doesn’t change its ending.
Why is the verb купил perfective past rather than imperfective покупал?
Perfective aspect (купил) indicates a completed, one-time action (“I have bought”). Imperfective (покупал) would emphasize the ongoing or habitual nature of buying without confirming its completion.
Could I say костюм от этого бренда instead of костюм этого бренда?
Yes. Костюм от этого бренда (“a suit from this brand”) is a perfectly correct and commonly used alternative. Using от plus genitive often feels more conversational.
Why aren’t there any articles like “the” or “a” in this Russian sentence?
