Questions & Answers about Поклонники вошли в театр, чтобы увидеть актёра.
Why is the verb вошли used here instead of just шли?
Вошли is a prefixed verb of motion, from войти. The prefix в- specifically means movement into something. While шли just means they were walking, вошли emphasizes the completed action of crossing the threshold into the theater. Notice how the prefix в- pairs naturally with the preposition в.
Since they are going inside the theater, could we use the preposition внутри from this lesson?
No, because внутри indicates a static position (being already inside), not a direction of movement. Because the fans are moving into a destination, we must use в with the Accusative case (в театр). If the sentence said they were waiting inside the theater, then we could use внутри with the Genitive case: внутри театра.
Why is the word for actor актёра instead of актёр?
Актёр is the direct object of the verb увидеть (to see), so it must be in the Accusative case. Because an actor is a living person, it is an animate noun, so its Accusative form matches the Genitive case, adding an -а to become актёра.
Why do we need чтобы? Can't we just say "вошли в театр увидеть"?
