Questions & Answers about Нельзя отправлять результаты до нашей проверки.
Why is it нашей проверки instead of наша проверка?
It follows the preposition до (before), which is the focus of this lesson. The preposition до always requires the genitive case. Since проверка (inspection) is a feminine noun, it changes to проверки, and the possessive pronoun наша (our) changes to нашей to match.
Why use the imperfective verb отправлять instead of the perfective отправить?
The word нельзя changes meaning based on the verb aspect. Нельзя followed by an imperfective verb means it is forbidden or you must not do it, which fits perfectly here. If you used the perfective verb (нельзя отправить), it would mean it is physically impossible to send (for example, if your internet is broken).
Is результаты in the nominative case here?
No, it is in the accusative case because it is the direct object of the verb (the thing being sent). For inanimate nouns like результат (things that are not alive), the accusative plural spelling looks exactly the same as the nominative plural.
Where is the word for you in the Russian sentence?
There is not one! The word нельзя is an impersonal word meaning it is forbidden or one cannot. Instead of saying you cannot send, Russian simply says it is forbidden to send. This states a general rule that applies to anyone.
