There are three types of verbs in Spanish: verbs that end in –ar, verbs that end in –er, and verbs that end in –ir. You’ve already learned –ar verbs:

yo hablo nosotros hablamos

tú hablas vosotros habláisUd.,él, ella habla Uds., ellos, ellas hablan

Now for –er verbs:

To conjugate–er verbs, start with the infinitive, take off the –er and then add the following endings:Infinitive – er = stem + ending = conjugated verb

comer (to eat)-o -emos comocomemos-es -éis comes coméis-e -en come comen

Notice that the only difference between –er verbs and

–ar verbs is that you use e’s instead of a’s:

-ar -er-o -amos -o -emos-as -áis -es -éis-a -an -e -en

Now for –ir verbs. Drop the –ir and add the following endings:

abrir (to open)-o -imos abroabrimos-es -ís abres abrís-e -en abre abren

Do you see what the difference is between –er and –ir verbs? They’re just alike except for the nosotros and vosotros forms:

-er -ir-o -emos -o -imos-es -éis -es -ís-e -en -e -en

So the only difference between –ar verbs and –er verbs is that you use e’s instead of a’s in the –er verbs. And the only difference between –er verbs and –ir verbs is the nosotros and vosotros forms.

So when you’re conjugating verbs, be sure you know if the infinitive (the form of the verb before you change it) ends with an –ar, –er, or –ir so you’ll know what ending to put on it:

You talk: hablas HABLAR we talk: hablamosYou eat: comes COMER we eat: comemosYou open: abres ABRIR we open: abrimos
