Breakdown of Из нового корпуса до метро идти всего десять минут.
Questions & Answers about Из нового корпуса до метро идти всего десять минут.
Because both prepositions in this sentence require the genitive:
- из
- genitive = out of / from
- до
- genitive = up to / as far as / to
So:
- из нового корпуса = from the new building
- до метро = to the metro
The noun корпус changes to корпуса in the genitive singular, and the adjective новый changes to нового to agree with it.
Because метро is one of those Russian nouns that is usually indeclinable. That means its form does not change by case.
So:
- nominative: метро
- genitive after до: still метро
Even though the case is genitive here, the word itself stays the same.
