Questions & Answers about Прохожий купил мороженое у продавца.
What is the case and role of мороженое in this sentence?
мороженое is in the accusative case because it’s the direct object of the verb купил. As a neuter noun, its nominative and accusative forms are identical.
Why is продавца in the genitive case after у?
The preposition у always requires the genitive case and here indicates the source or “seller” from whom something is bought: “bought … from the seller.”
Is мороженое really a noun? It looks like an adjective.
It began as a neuter adjective meaning “frozen,” but in modern Russian it’s substantivized—fully functioning as a noun—yet it keeps the adjective declension pattern.
Why is купил in the past tense masculine form?
Russian past‐tense verbs agree in gender and number with their subject. Прохожий is masculine singular, so the verb takes the masculine singular ending -л.
Could we say покупал instead of купил?
Yes, but the meaning shifts by aspect. Купил is perfective (completed action: “did buy”), while покупал is imperfective (process or habitual: “was buying” or “used to buy”).
How would you ask “What did the passerby buy?” in Russian?
You’d say Что купил прохожий? Here что is the accusative interrogative “what,” and you can invert word order (verb before subject) for a question.
Does word order matter in Прохожий купил мороженое у продавца?
Russian word order is flexible. The neutral order is Subject-Verb-Object-Adverbial. But you could say У продавца прохожий купил мороженое to emphasize у продавца (“from the seller”).
Why are there no articles (a/an/the) in this sentence?
Russian doesn’t use articles. Definiteness or indefiniteness is inferred from context or added with demonstratives (e.g., это мороженое for “this ice cream”).
What exactly does прохожий mean and what are its grammatical properties?
прохожий means “passerby” (someone walking by). Grammatically it’s an animate masculine noun, here in the nominative singular as the subject.
If прохожий were the object, would its form change?
Yes. Animate masculine nouns take a genitive‐like form in the accusative. So the object form would be прохожего.
