Questions & Answers about Чью ставку они подняли во время аукциона?
Why is "whose" written as чью in this sentence?
Чью is the feminine accusative form of чей (whose). Just like adjectives, the pronoun чей has to match the gender, number, and case of the noun it describes. Since it describes ставку, which is a feminine noun in the accusative case (the direct object), it takes the feminine accusative form чью.
What is the dictionary form of ставку?
The nominative dictionary form is ставка, which means a "bid", "stake", or "rate" (it comes from the verb ставить, meaning "to put" or "to place"). It is in the accusative case here (ставку) because it is the direct object being acted upon by the verb подняли.
Why does the phrase во время require the next word to be аукциона instead of just аукцион?
Во время is a fixed phrase meaning "during" (literally "in the time of"). When used as a preposition, it always requires the noun that follows it to be in the genitive case. Because аукцион is a masculine noun ending in a consonant, it takes the genitive ending -а, becoming аукциона.
Could we use the imperfective verb поднимали instead of the perfective подняли here?
