To make an affirmative tú command (telling someone to do something), we conjugate the verb in Box 3
Ex: Hablar= Habla, comer= come
To make a negative tú command (telling someone NOT to do something), we conjugate in the opposite verb form's Box 2 (you will learn how to do this in Spanish 3)
Ex: Don't talk= No hables, Don't eat= No comas
Remember the 8 irregulars
Venir (to come-- ven), decir (to say/ to tell-- di), salir (to leave-- sal), hacer (to do/ to make-- haz), tener (to have-- ten), ver (to see-- ve), poner (to put/ to place-- pon), ser (to be-- permanent-- sé)
