Questions & Answers about Estudio español en la biblioteca durante media hora.

Why does the sentence start with Estudio instead of Yo estudio?

In Spanish, subject pronouns are often omitted because the verb ending already shows who is doing the action.

• Estudio = I study
• The -o ending tells you it is first person singular: I

So Estudio español... is completely natural.
You could say Yo estudio español..., but yo is usually only added for emphasis, contrast, or clarity.
