Questions & Answers about ¿De dónde es ella? Es colombiana.
Why does the question start with "De" instead of putting "from" at the end?
In Spanish, you can never end a sentence with a preposition like de (from). Instead, it must go right before the question word. So, rather than asking "Where is she from?", you literally ask "From where is she?" (¿De dónde es ella?).
Why do we use "es" instead of "está" here?
Why isn't "colombiana" capitalized?
Why doesn't the second sentence say "Ella es colombiana"?
In Spanish, you often drop the subject pronoun (like ella, yo, or tú) if it is already clear who you are talking about. Since the first sentence specifically asks about ella, the listener already knows who es colombiana refers to.
How would this change if we were talking about a man?
