Questions & Answers about Неужели вы накупили столько шариков?
How does the prefix на- change the meaning of купить in this sentence?
The prefix на- adds the meaning of accumulating or gathering a large quantity of something. While купить simply means to buy, накупить implies buying a whole lot of something, hoarding, or stocking up.
The current lesson is about the prefix на- taking the Genitive case. Is шариков in the Genitive because of накупили?
In this specific sentence, шариков is in the Genitive plural primarily because it directly follows the quantity word столько (so many). However, even if you removed столько, you would still say вы накупили шариков (Genitive) rather than using the Accusative. Verbs with the accumulative на- prefix naturally take the Genitive to express 'a large quantity of [something]'.
What nuance does Неужели add that makes it different from just asking a normal question?
Неужели expresses genuine surprise, disbelief, or doubt, functioning much like 'Did you really...?' or 'Is it possible that...?' in English. Without it, the sentence would just be a neutral request for information.
Why use шариков (little balls) instead of a specific word for balloons?
