Questions & Answers about Mi hermana rebelde escondía sus notas terribles.
Why translate escondía as "used to hide" instead of just "hid"?
How do we get the ending for escondía?
I thought notas meant "notes". Does it also mean "grades"?
Yes! While notas can mean "notes" (like musical notes or written messages), in a school context, it is the standard word for "grades" or "marks" on a test or report card.
Why is it sus notas (plural) if it's talking about one sister ("her")?
In Spanish, possessive adjectives like su or sus must match the amount of the things being owned, not the owner. Because she is hiding multiple grades (notas), you have to use the plural sus, even though there is only one sister doing the hiding.
