For example, instead of saying "Yo hablo español" (I speak Spanish), one can simply say "Hablo español." The verb "hablo" clearly indicates that the subject is "yo" (I) because of its specific ending.

Answer 1

Yes, that's correct! In Spanish, the verb conjugation provides information about the subject, which allows speakers to often drop the subject pronoun (like "yo") to make sentences more concise. So, "Hablo español" (I speak Spanish) is perfectly understandable without needing to explicitly state "yo." This is a common feature in many Romance languages, where verb endings carry information about the subject.
