Goal:
Learn how to form negative tú commands.
Negative Tú Commands
• Regular Verbs A negative tú command is used to tell a friend, family member,
or someone with whom you are familiar not to do something. Read and study
the chart.
Infi nitive
Present Tense
Negative tú Commands
hablar
yo hablo
¡No hables tanto! (Don’t talk so much!)
correr
yo corro
¡No corras tanto! (Don’t run so much!)
dormir
yo duermo
¡No duermas tanto! (Don’t sleep so much!)
EXPLANATION:
To form a negative tú command, drop the -o ending of the present
indicative and add these endings: for -ar verbs, add -es; for -er and -ir verbs, add -as.
• Verbs with Spelling Changes Study the negative tú commands for -car, -gar, and
-zar verbs.
Infi nitive
Present Tense
Negative tú Commands
tocar
Yo toco la cámara.
¡No la toques! (Don’t touch it!)
apagar
Yo apago las luces.
¡No las apagues! (Don’t turn them off!)
comenzar
Yo comienzo la escena.
¡No la comiences! (Don’t start it!)
EXPLANATION:
Verbs that end in -car, -gar, and -zar have the same spelling
changes as in the yo form of the preterite: the c changes to qu, the g to gu, and, the
z to c. These changes are necessary to keep the correct pronunciation. Also note that
pronouns with negative tú commands appear before the verb.
• Irregular Verbs Some verbs have irregular negative tú commands. Study
these below.
dar
ir
saber
estar
ser
Infi nitive
(to give)
(to go)
(to know)
(to be)
(to be)

no seas
Negative tú
Command
(don’t give)
(don’t go)
(don’t know)
(don’t be)

EXPLANATION:
Verbs whose yo form in the present indicative does not end in -o,
such as doy, voy, sé, estoy, soy, have irregular negative tú commands. These must be
memorized.
