Questions & Answers about Менеджер проверит документы к вечеру.
Why do we use к in к вечеру to mean 'by evening'?
The preposition к followed by the Dative case is used to express a deadline or a specific time by which an action will be completed. It literally translates closer to 'towards', but in time contexts like this, it means 'by' a certain time.
What case is вечеру, and how is it formed from the dictionary word?
It is in the Dative case, which is always required by the preposition к. The dictionary form is вечер (a masculine noun ending in a consonant). To form the Dative singular for masculine nouns, you simply add -у, giving us вечеру.
Why is the perfective verb проверит used here instead of the imperfective future будет проверять?
Since the sentence includes a deadline (к вечеру), the focus is on the successful completion and result of the action by that specific time. The perfective aspect (проверит) is needed to show that the checking will be completely finished by evening, not just in progress.
Is the word документы in the Nominative case here?
No, it is in the Accusative case because it is the direct object receiving the action of the verb (what will the manager check?). However, for inanimate nouns like документ, the Accusative plural form looks exactly the same as the Nominative plural.
