Questions & Answers about Hablas mucho.
How do we know it means "you speak" if there is no word for "you" in the sentence?
The ending -as on the verb hablas tells us exactly who is speaking: "you" (informal singular). In Spanish, it is very common to drop the pronoun tú (you) because the verb ending already gives us that information.
How do we build this verb form from its dictionary version?
The base verb (infinitive) is hablar (to speak). Because it is a regular -ar verb, you drop the -ar ending to get the stem habl-, and then add -as for the tú (you) form, creating hablas.
Why doesn't mucho change its ending here, like in muchas gracias?
How do you pronounce the beginning of hablas?
The letter "H" is always completely silent in Spanish. You pronounce this word exactly as if it were written "ablas".
