Questions & Answers about Врачи спасают людей и возят их в больницу каждый день.
Why do we use возят instead of везут here?
The phrase каждый день (every day) tells us this is a repeated, habitual action. For transporting someone by vehicle repeatedly, we use the multidirectional verb возить (here, возят for they transport). If the doctors were driving them to the hospital just once on a single trip, we would use the unidirectional verb везти (везут).
Why is the word for people людей instead of люди?
Люди is the subject form (nominative). Here, the people are the direct object of the verb спасают (save), so we need the accusative case. Because people are living beings (animate), their plural accusative form matches their plural genitive form, which is людей.
Why does it say в больницу rather than в больнице?
We use the preposition в with the accusative case when talking about motion towards a destination (answering where to?). Больница (hospital) changes to больницу in the accusative. If we wanted to say someone is already inside the hospital (location, answering where at?), we would use в with the prepositional case: в больнице.
Is каждый день in the nominative case here?
