Learn Spanish (Latin America): A nosotros no nos importa el dinero.

With verbs like importar (to matter) and gustar (to like), the sentence structure feels backward to English speakers. The thing doing the action is actually the money (el dinero). Because el dinero is singular, the verb is singular (importa). Think of it as "Money is not important to us."

Why does the sentence use both A nosotros and nos?

You are right that it feels repetitive! The pronoun nos (to us) is absolutely required to show who the money matters to. Adding A nosotros at the beginning is optional, but Spanish speakers use it to add emphasis. It is like saying "To us, money doesn't matter."

Why does the word no go between nosotros and nos?

In Spanish, the word no must always go immediately before the pronoun (nos) and the verb (importa). You cannot put it between the pronoun and the verb. The phrase A nosotros is just an extra detail at the start, so no comes right after it to make the main action negative.

Why does the Spanish sentence say el dinero when the English translation is just "money"?
