Questions & Answers about Yo siempre estudio japonés temprano.
How do I know to use estudio here instead of estudia?
estudio is the "I" form of the regular verb estudiar (to study). To talk about yourself in the present tense, you take off the -ar ending and add -o. If you wanted to say "he studies" or "she studies", you would use estudia.
Do I have to include Yo at the beginning of the sentence?
No, it is completely optional! In Spanish, the verb ending usually tells you who is doing the action. Since estudio can only mean "I study," you can drop the Yo and just say Siempre estudio japonés temprano. Including Yo just adds a bit of emphasis.
Why isn't the word for Japanese (japonés) capitalized?
