Step by step instructions

The verb abrir has an entirely regular conjugation in the Pretérito Perfecto Simple tense of the Indicativo mood. It means this verb follows the general rules for its group (-ir) without exceptions.

The basis for the conjugation of this verb is its stem, so we have to start by splitting the infinitive into a stem and an ending. It’s easy to do – just remove two letters from the end of the infinitive form to get the ending – one of -ar, -er, -ir. What’s left is the stem. So in case of the verb abrir it’s easy to see that: the stem is: abr- and the ending is: -ir

Use the stem abr- in each person as the basis for the conjugation, the common prefix that each of the forms begins with.

Next, add to this regular stem the endings specific to each person. See the image on the side showing all the six endings. Note both the shapes and colors of the letters. It should help you find patterns and make it easier to remember these endings. Each grammatical person has a specific ending in each of the three conjugation groups -ar, -er, -ir

Add the regular ending -í for the first person singular to get abrí

Once more add the regular ending -iste for the second person singular to get abriste

Like in the previous case add the regular ending -ió for the third person singular to get abrió

And again add the regular ending -imos for the first person plural to get abrimos

And as before add the regular ending -isteis for the second person plural to get abristeis

Again add the regular ending -ieron for the third person plural to get abrieron

This is it! The conjugation is now finished. But don’t end your session yet – it’s important to repeat and practice the material in order to retain it. Check below for suggestions.
