Learn Spanish (Latin America): Se nos rasgó el papel del marco valioso. - We accidentally tore the paper of the valuable frame.

This sentence uses the accidental se construction. Instead of saying "We tore the paper" (which sounds intentional), Spanish phrases it more like "The paper tore itself on us." The se shows the action was a pure accident, and nos (to us) shows who suffered the consequences.

Why is the verb rasgó in the "he/she/it" form if the English translation says "we"?

In the accidental se construction, the thing getting damaged or lost is the actual grammatical subject of the sentence. Here, the subject is el papel (the paper), so the verb rasgar is conjugated in the third-person singular form (rasgó) to match it. The word nos simply tells us who was affected.

Why use rasgó here instead of rompió?

Rasgar specifically means "to tear" or "to rip," which is the most accurate verb for materials like paper or fabric. Romper is a more general word for "to break." You could use rompió here, but rasgó paints a much more precise picture of torn paper.
