Learn Spanish (Latin America): Ella es de Colombia.

Yes! In Spanish, you can often drop the subject pronoun (like ella) because the verb es already tells us we are talking about a third person. You usually include ella for emphasis, or to make it clear you mean "she" instead of "he" (él) if it isn't obvious from the context.

Why do we use "es" in this sentence?

Es is the form of the verb ser (to be) used for él (he), ella (she), and usted (formal you). We use ser to talk about identity and origin, like what country someone is from.

How does the word "de" work here?

The word de means "of" or "from". In Spanish, you express where someone is from by using the formula ser + de + [place]. So, es de Colombia translates to "is from Colombia".

How do you pronounce the double L in "Ella"?

In most of Latin America, the double L sounds like the English "y" in "yes", making ella sound like "eh-yah". In some places, like Argentina and Uruguay, it sounds more like the "sh" in "shoe".
