Questions & Answers about Через неделю наш менеджер будет руководить этим проектом.
Why is этим проектом in the Instrumental case?
The verb руководить (to lead, direct, or manage) always requires its object to be in the Instrumental case. This is a key feature of several management and interest verbs in Russian. As a result, the Nominative phrase этот проект must change to its Instrumental form, этим проектом.
Why do we use the imperfective future будет руководить instead of a perfective verb?
Managing or leading is an ongoing process rather than a single, one-time completed action. Using the imperfective future (a conjugated form of быть plus the infinitive) emphasizes that the manager will be engaged in the continuous activity of directing this project.
Why does the preposition через mean in here, and what case does it take?
While через often means across or through in physical space, when talking about time it translates to in (meaning after a certain amount of time has passed). It is always followed by the Accusative case. Here, the feminine noun неделя changes to the Accusative неделю.
Could I use руководить if I am physically leading someone, like guiding a friend through a crowd?
No, руководить is specifically used for managing, directing, or being in charge of something abstract like a business, a team, or a project. If you are physically guiding someone, you would use a verb of motion like вести.
