Irregular Verbs in Spanish: A MosaLingua Mini-Guide

So you want to learn Spanish? Learning Spanish irregular verbs is a must! Because yes, there are irregular verbs in Spanish, too. That means that some verbs are conjugated differently, or even take on a different structure, depending on the tense and/or the person you are talking about. In this mini-guide, we’re tackling Spanish irregular verbs, their different forms, and how to conjugate them. You’ll also find a list of the most common Spanish irregular verbs, plus some video tips on how to remember them.

Irregular Verb Forms

In Spanish, there are three irregular verb forms. You have the irregular diphthong verbs, the weak irregular verbs, and then the other irregular verbs in Spanish.

1. Irregular diphthong verbs

Querer for example is an irregular Spanish diphthong verb. What’s different about it? The first e becomes ie in the three singular forms, and in the third person plural form. In other words, in the present tense, this is how it’s conjugated: quiero, quieres, quiere, queremos, queréis, quieren

The rule? An irregular Spanish diphthong verb is a verb in which the root vowel (like the e here) becomes a diphthong in the three singular forms, and in the third person plural form.

• As you saw in the example above, there are some irregular verbs whose root vowel e becomes ie, like the verbs querer or pensar
• then there are verbs whose i also becomes ie, such as adquirir => adquiero, adquieres, adquiere, adquirimos, adquiris, adquieren
• there are verbs whose o becomes ue, like poder => puedo, puedes, puede, podemos, podéis, pueden
• and verbs whose root u also becomes ue, like the verb jugar => juego, juegas, juega, jugamos, jugáis, juegan

Irregular Spanish verbs with a diphthong don’t just occur in the present tense: the simple present, subjunctive and imperative also have them.

As you may have noticed, in the 1^st and 2^nd person plural forms the conjugation is regular.

2. Weak verbs

When a letter becomes two letters, it’s called an irregular Spanish diphthong verb. This is what you just saw in the last section. When the root letter is replaced by a different one, that’s called a weak irregular Spanish verb. More specifically, they are verbs which end in –ir whose root e becomes an i, when there is no i in the ending. Sounds a bit complicated, right? Let’s look at an example to get a better understanding.

The verb pedir, for example, is conjugated like this: pido, pides, pide, pedimos, pedís, piden. In the 1^st and 2^nd person plural forms, there is an “i” in the ending. So, the “e” stays an “e” in the first part of the verb (the root).

This weakening of the verb takes place in the three singular forms and in the 1^st person plural in the present… We also find this weakening in the 3^rd person singular and plural forms in the past historic.
