A command is an instruction or an order to do something. Remember there are four ways of saying 'you' in Spanish, so there are four command forms.
For the TU, USTED and USTEDES forms, remove the -O of the yo form of the present tense before adding the endings.
For the VOSOTROS form remove the -R from the infinitive before adding the ending.
INFINITIVE | TU | USTED | USTEDES | VOSOTROS | |
-ar | hablar | Habla | Hable | Hablen | Hablad |
-er | comer | Come | Coma | Coman | Comed |
-ir | escribir | Escribe | Escriba | Escriban | Escribid |
Por ejemplo:
Marta, habla más despacio > Marta speak more slowly.
David y Pablo comed las verdures > David and Pablo eat your vegetables.
Señor Villatoro pase por aquí > Mr Villatoro come this way
NB: The rules above also apply to verbs which are irregular in the YO form of the present tense and to stem-changing verbs.
