IT MEANS

WHAT ARE YOU STUDYING?

¿Qué estudias? without tu

What do you study? is better than
What are you studying?

Que estuduias

"¿Qué estudias tú?" in Spanish translates to "What do you study?" in English.

To understand this sentence, let's break it down:

- "¿Qué" means "What" in English. It introduces a question.
- "estudias" means "do you study" in the second-person singular form, which refers to "you" in English. It comes from the verb "estudiar" meaning "to study."
- "tú" means "you" in English, specifically emphasizing "you" as the subject of the sentence.

So, putting it all together, "¿Qué estudias tú?" is a direct question asking someone about the subject they study.
