2.  To form the tú commands, simply use the él/ella/Ud. form of the verb in the present tense. › Speak! ¡Habla! › Run! ¡Corre! › Walk! ¡Camina! › Study! ¡Estudia! › Look! ¡Mira!

3.  There are eight verbs with irregular affirmative tú command forms. These must be memorized. › decir (to say/tell): di › hacer (to do/make): haz › ir (to go): ve › poner (to put/place): pon › salir (to leave/go out): sal › ser (to be): sé › tener (to have): ten › venir (to come): ven

4.  For reflexive verbs, we attach the reflexive pronouns to the end of the command, adding an accent mark. We place the marks on what was the next- to-the-last syllable before we added the pronoun. › Stand up! ¡Levántate! › Go away! ¡Vete! › Sit down! ¡Siéntate! › Wake up! ¡Despiértate!

5.  The negative of tú commands is formed using the following formula: No + yo form of the verb + opposite vowel + s › Don’t speak! ¡No hables! › Don’t run! ¡No corras! › Don’t walk! ¡No camines! › Don’t study! ¡No estudies! › Don’t come! ¡No vengas! › Don’t drive! ¡No conduzcas!  Note: If the “yo” form of the verb is irregular, the negative tú command for that verb will also be irregular. Stem-changing verbs will also change in the negative forms.

6.  Reflexive verbs use the same formula; however, the reflexive pronoun is placed between the “no” and the command form. › Don’t stand up! ¡No te levantes! › Don’t go (away)! ¡No te vayas! › Don’t sit down! ¡No te sientas! › Don’t fall asleep! ¡No te duermas!

7.  There are five verbs with irregular negative tú commands forms. These must be memorized.  dar (to give): no des  estar (to be): no estés  ir (to go): no vayas  saber (to know): no sepas  ser (to be): no seas

8.  Some spelling changes occur to preserve the sound of the infinitives of the verbs used.  In -car verbs, the c changes to qu. In - gar verbs, the g changes to gu. › JUGAR: Don’t play! ¡No jue gu es! › BUSCAR: Don’t look for…! ¡No bus qu es! › PAGAR: Don’t pay! ¡No pa gu es! › PRACTICAR: ¡No practi qu es!
