1) When you want to talk about something that is happening now.
2) When you want to talk about something that happens on a regular basis.
The present tense of regular verbs is easy to form.
You take the verb in the infinitive (ending AR / ER / IR), take off the AR / ER or IR ending and add on the endings according to whom you want to talk about to the stem.
Here are the endings (in capitals):
HABLAR | VIVIR | COMER |
hablO | vivO | comO |
hablAS | vivES | comES |
hablA | vivE | comE |
hablAMOS | vivIMOS | comEMOS |
hablÁIS | vivÍS | comÉIS |
hablAN | vivEN | comEN |
Por ejemplo:
Yo hablo español - I speak Spanish
Ana vive en Madrid - Ana lives in Madrid
Mis amigos comen cereales - My friends eat cereals
