Irregular Yo form verbs and others

The present indicative tense has a lot of irregular verb conjugations. It is easiest to learn once you understand that there is generally a pattern to the irregularities.

Verbs that are irregular in the yo form only.

caer (to fall) → caigo, caes, cae, caemos, caéis, caen
conocer (to know) conozco, conoces, conoce, conocemos, conocéis, conocen

There are a bunch of verbs that are like conocer. The irregularity is that you need to add a z just before the last c.

aborrecer (to hate) desconocer (be be ignorant of) ofrecer (to offer)
agradecer (to thank) establecer (to establish) parecer (to seem)
aparecer (to appear) estremecerse (to shudder) permanecer (to remain)

While there are more irregular verbs in Spanish, they tend to be compound verbs that contain the previous irregular verbs as a base.

As you learn new verbs, look for a possible root verb that you may already know.
