Questions & Answers about Proszę wpuszczać te dziewczyny na scenę.
Why do we use te instead of ci for "these girls"?
In Polish, plural demonstrative pronouns depend on gender. We use ci only for masculine personal nouns (groups that include at least one man). Since dziewczyny (girls) falls into the non-masculine-personal category (women, animals, and objects), we must use te.
Is te dziewczyny in the nominative or accusative case here?
It is in the accusative case because the girls are the direct object of the verb wpuszczać (to let in). For all non-masculine-personal nouns in the plural, the accusative case looks exactly identical to the nominative case. So te dziewczyny does not change its form here.
Why is the verb wpuszczać in the infinitive instead of a command form?
Using proszę followed directly by an infinitive (like wpuszczać) is a standard and polite way to give instructions in Polish. It translates literally as "I ask to let in", but is used exactly like "Please let in" in English.
Why do we say na scenę instead of na scenie?
Because this sentence involves motion towards a destination. We use the preposition na plus the accusative case (scenę) when moving onto something. If someone were already standing on the stage without moving onto it, we would use na plus the locative case (na scenie).
