Imperatives are used to give commands, orders and instructions, eg Do your homework! Sit down!
The form used depends on who is being spoken to (tú, vosotros, usted or ustedes) and if the command is positive (stand up!) or negative (don't stand up!).
To form positive commands for the tú form, just take the -s off the tú form of the present tense. For example:
These verbs have irregular imperatives in the tú form:
decir (to say) → di
hacer (to make/do) → haz
salir (to go out) → sal
ser (to be) → sé
tener (to have) → ten
eg ¡Ten cuidado! (Be careful!)
To form positive commands for the vosotros form, change the -r at the end of the infinitive to a -d:
hablar (to speak) → hablad
correr (to run) → corred
eg ¡Terminad el trabajo! (Finish the work!)
The third person singular (él/ella/usted) or plural (ellos/ellas/ustedes) form of the present subjunctive is used for formal commands, eg ¡Tome! (Take!), ¡Estudien! (Study!).
The present subjunctive form is used for all negative commands. For example:
tú | vosotros | usted | ustedes | ||
---|---|---|---|---|---|
-ar verbs | estudiar (to study) | no estudies | no estudiéis | no estudie | no estudien |
-er verbs | beber (to drink) | no bebas | no bebáis | no beba | no beban |
-ir verbs | decidir (to decide) | no decidas | no decidáis | no decida | no decidan |
