Learn Russian: Общежитие новое.

In Russian, the present tense of the verb "to be" (am, is, are) is almost always left out. So, instead of saying "The hostel is new", you just say "Hostel new" (Общежитие новое).

Why does the word for "new" end in -ое (новое)?

In Russian, adjectives must match the gender of the noun they describe. The word for hostel, общежитие, is a neuter noun because it ends in -е. Therefore, the default dictionary form of the adjective (новый, masculine) changes to its neuter form, новое, to match it.

How do I know общежитие is a neuter noun?

You can usually tell a Russian noun's gender by its last letter. Most nouns ending in -о or -е are neuter. Since общежитие ends in -е, it falls into the neuter category.

Does общежитие mean a regular hotel?

No, it specifically means a "hostel" or a "dormitory" (like for university students or workers). If you want to talk about a standard hotel, you would use the word гостиница or отель.
