Spanish irregular verbs in the first person

Spanish verbs can be divided into several groups. The division is quite more complex than a simple differentation between regular and irregular verbs.

Why? Because for example stem-changing verbs are something between regular and irregular verbs. And so are the verbs that we will see today, as actually, in this case only the first person is different, the rest of them follows the general rules, as we might see in the example below:

Poner verb

As you see, in fact, only the "yo" person is different from the rest, which is why I always call this kind of Spanish verbs “semi-irregular verbs”. I will divide them into different groups so that it will be easier to remember them.

Spanish verbs with -ECER termination

Change in the 1st person Example Meaning Conjugation
C--> ZC Agradecer To be thankful (Yo) agradezco, (Tú) agradeces, (Él, Ella, Usted) agradece (Nosotros) agradecemos, (Vosotros) agradecéis, (Ellos, ellas) agradecen
C--> ZC Parecer To seem Parezco, pareces, parece, parecemos, parecéis, parecen
C--> ZC Ofrecer To offer Ofrezco, ofreces, ofrece, ofrecemos, ofrecéis, ofrecen

Other verbs that follow the same pattern are, for example: padecer (to suffer from a disease), crecer (to grow, to rise), amanecer (to begin to get light ), enriquecer (to enrich ) and much more.

Spanish verbs with – UCIR termination

Change in the 1st person Example Meaning Conjugation
C--> ZC Traducir To translate (Yo) traduzco, (Tú) traduces, (Él, Ella, Usted) traduce (Nosotros) traducimos, (Vosotros) traducís, (Ellos, ellas) traducen
C--> ZC Conducir To drive (a vehicle) Conduzco, conduces, conduce, conducimos, conducís, conducen
C--> ZC Producir To produce Produzco, produces, produce, producimos, producís, producen

It’s good to know that the verbs wchich terminate on -UCIR are special for one more reason.

They are irregular in a past tense called pretérito indefinido. And since they are iregular instead of saying traducí you have to use the form traduje to say, in this case, I did translate.

Other popular verbs that follow the same rule are, for example: reducir (to reduce), introducir (to introduce), seducir (to seduce) or deducir (to deduce, to work out).

The – GO form in the first person

The verbs in the list below have in common one thing: in the first person the form “go” appears.

Change in the 1st person Example Meaning Conjugation
GO Salir To leave (Yo) salgo, (Tú) sales, (Él, Ella, Usted) sale (Nosotros) salimos, (Vosotros) salís, (Ellos, ellas) salen
GO Poner To put Pongo, pones, pone, ponemos, ponéis, ponen
GO Traer To bring Traigo, traes, trae, traemos, traéis, traen
GO Caer To fall Caigo, caes, cae, caemos, caéis, caen
GO Hacer To do Hago, haces, hace, hacemos, hacéis, hacen
GO Satisfacer To satisfy Satisfago, satisfaces, satisface, satisfacemos, satisfacéis, satisfacen
GO Valer To be worth Valgo, vales, vale, valemos, valéis, valen

Verbs with the irregular first person – other cases

And finally there are also verbs where the first person is not regular but it doesn’t follow any specific pattern. We could say that these forms are the real irregular forms.

Verb Meaning 1st person Conjugation
Dar To give Doy (Yo) doy, (Tú) das, (Él, Ella, Usted) da (Nosotros) damos, (Vosotros) dais, (Ellos, ellas) dan
Caber To fit Quepo Quepo, cabes, cabe, cabemos, cabéis, caben
