Unit 12 - The Conditional Tense
Lesson 12.2 - Irregular Verbs in the Conditional Tense
Topic:

Only twelve verbs plus their compounds are irregular in the conditional. Practice them in this lesson.

Irregular Verbs in the Conditional

If you already studied the future tense, and you just learned the basics of the conditional in the previous lesson, I have good news.

You already know everything that you need to know about irregular verbs in the conditional.

Let's take tener as an example.

tendrían

Exactly as we did in the future tense, the stem here takes the infinitive tener and changes it slightly to be tendr-.

It is the same stem as the future tense, just with new endings.

That's it.

Same Irregular Verbs, Same Stem Changes

Those twelve verbs that you learned in the future tense are listed here with the same changes in the conditional:

InfinitiveConditional StemMeaningYo Form
tenertendr-would havetendría
ponerpondr-would putpondría
valervaldr-would be worthvaldría
salirsaldr-would go outsaldría
venirvendr-would comevendría

haberhabr-would havehabría
sabersabr-would knowsabría
quererquerr-would wantquerría
hacerhar-would doharía
decirdir-would saydiría

Compound verbs that end with one of these verbs share the irregularity.

For example, the verb mantener meaning to maintain is a compound from tener so it looks like this:

Conditional Tense of poder means could

One very common irregular verb from the list above is poder.

The meaning here makes a lot of sense, because would be able to is really just could.

Example:

Could you help me with the luggage?
¿Podrías ayudarme con las maletas? Play Audio


All the verbs in the exercises use one of these altered stems, so let's get some practice.
