"Orchestra noastră are concert mâine."

Translation: Our orchestra has a concert tomorrow.

[PhilipNikolayev]

Is the Romanian correct? Why is the indefinite article dropped in "are concert" (where I expected "are un concert")?

[crbratu]

In Romanian we use to take away the article when referring to ownership of one piece of something. We say "Eu am casă/ mașină/ bicicletă/ bilet / concert"

[wirwollen]

When in mobile app, there are no prepositions for making the sentence

[Renardo_11]

Why should there be any prepositions if the sentence does not contain any in either language?
