Questions & Answers about Această clădire este un muzeu.

Why do we use această here instead of acest?

Această is the feminine form of this. We use it because the noun it points to, clădire, is feminine. If we were pointing to a masculine or neuter noun, we would use acest. For example, acest muzeu means this museum.

How can I tell that clădire is feminine if it does not end in -ă or -a?

Nouns ending in -e are a bit tricky in Romanian because they can be masculine, feminine, or neuter. You just have to memorize the gender of these specific words when you learn them. Knowing that clădire is feminine tells you to use această.

Why does the sentence use un muzeu? Shouldn't it be feminine to match the building?

No, it does not need to match! Clădire and muzeu are separate nouns with their own permanent genders. Clădire is feminine, but muzeu is neuter. Neuter nouns use the masculine article un in the singular. A noun never changes its own inherent gender just because it is compared to another noun in a sentence.

How would I change this sentence to say THAT building is a museum?

To say that instead of this for a feminine noun, you use the demonstrative for distance, which is acea. The sentence would simply become: Acea clădire este un muzeu.
