Learn Hardcore Spanish (Latin America): Nuestra familia celebra en casa.

In Spanish, the possessive adjective must match the gender of the noun. Since familia is a feminine noun, we use nuestra (feminine form). If it were a masculine noun (for example, nuestro libro), we would use nuestro instead.

Why is the verb celebra in singular if familia refers to more than one person?

In Spanish, familia is considered a collective noun and is treated as singular, so we use the third-person singular form celebra.

Could we say Nuestra familia celebramos en casa for "Our family celebrates at home"?

Typically, no. Since familia is singular, we keep the verb in third-person singular to match the singular subject. If you were to use celebramos, you would need the subject nosotros: Nosotros celebramos en casa.

Why do we say en casa without an article?

In Spanish, when talking about one’s own house or going home, the phrase en casa (or a casa) is commonly used without an article. It’s understood from context that this means “at home”.

Is there a difference between celebrar and festejar in this context?

They’re largely interchangeable. Celebrar is slightly more formal, while festejar has a more festive or party-like connotation, but both mean “to celebrate”. Here, celebra conveys that the family is celebrating in general, without necessarily implying a big party.
