Learn Spanish (Latin America): Eres de Colombia.

In Spanish, you can often leave out the subject pronoun (like tú for 'you') because the verb itself tells us who is doing the action. The word eres specifically means 'you are,' so we don't need to say Tú eres de Colombia unless we want to add emphasis.

Why do we use eres here?

Eres comes from the verb ser (to be). We use forms of ser when talking about identity, professions, and origin. Since this sentence is about where someone is originally from, we use eres.

Is it wrong if I say Tú eres de Colombia just to be safe?

Not at all! Saying Tú eres de Colombia is perfectly correct. As a beginner, it is fine to include the pronoun tú while you get used to the verb endings. You will just hear native speakers drop it most of the time because the verb already makes the subject obvious.

Does the word de always mean 'from'?

It often means 'from' when talking about origin, but it can also mean 'of.' Whenever you want to say you are from a place in Spanish, the correct pattern is always a form of the verb ser followed by de and the location.
