Thank you for using the Jiskha Homework Help Forum. In the back of any good textbook (appendix) you should find pattern verbs. Here are the ones used most often?

hablar = yo hablo, tú hablas, él/ella/usted habla, nosotros/nosotras hablamos, vosotros/vosotras hablais, ellos/ellas/ustedes hablan

comer = yo como, tú comes, él/ella/usted come, nosotros/nosotras comemos, vosotros/vosotras comeis, ellos/ellas/ustedes comen
