As also ar-verbs and ir-verbs the er-verb type has regular and irregular forms. We now have a look at the regular ones.

First we need to find the stem of the verb that is done by removing the standard verb ending of the infinite (not changed) form. The stem of comer (to eat) is com (-er was removed). Then the conjugate endings are put in place:

yo como   tú comes   él come   ella come   nosotros comemos   nosotras comemos   vosotros coméis   vosotras coméis   ellos comen   ellas comen I eat you eat he eats she eats we eat (masculine) we eat (feminine) you eat (masculine) you eat (feminine) they eat (masculine) they eat (feminine)

Here you find now a summary of all three conjugation types. As you can see the basic logic is the same. Now it's up to you to get them into your head:

-ar   habl-o   habl-as   habl-a   habl-amos   habl-áis   habl-an

-er   com-o   com-es   com-e   com-emos   com-éis   com-en

-ir   recib-o   recib-es   recib-e   recib-imos   recib-ís   recib-en
