1. Comer
2. FYI, Tu, without the accent means YOUR,... Tú, would be the adequate response.
3. comes is the appropriate ending.
4. The “an” ending in bailaran is for the Ustedes/Ellos form. “Yo bailaré” is the correct form.
5. Ellos bailarán.
6. Yo hablar is incorrect because the verb is in its original/infinitive form (not conjugated).
Yo hablo is conjugated in the present tense.
Yo hablare would be the correct form if you had included the accent on the “e”. Yo hablaré.
Accents and spelling are crucial and non-negotiable in verb conjugations.
