In this lesson we will consider Spanish irregular verbs: irregular subgroups of –ER and –IR verbs, verbs with stem change and exceptional irregular verbs that must be only memorized.

IR – to go, TENER – to have, QUERER – to want/to love, HACER – to do and other irregular verbs and their common characteristics.

Spanish Irregular verb subgroups

  • Subgroups –CER and -CIR:

-CER is a subgroup of –ER group, and –CIR is a subgroup of –IR group. Verbs ending in –CER or –CIR end in –ZCO in conjugation with the pronoun YO:

Conocer – to know, Yo conozco – I know

Aparecer – to appear, Yo aparezco – I appear

Parecer –to look like, Yo parezco – I know

Ofrecer – to offer, Yo ofrezco – I offer

Seducir – to seduce, Yo seduzco – I seduce

Producir – to produce, Yo produzco – I produce

Reducir – to reduce, Yo reduzco – I reduce

With all other pronouns they have ordinary form, e.g. tú conoces, él conoce, nosotros conocemos and so on.

  • Subgroups –NER and –NIR:

-NER is a subrgoup of –ER verbs, and –NIR is a subgroup of –IR group. Verbs with these infinitive endings will end in –GO in conjugation with the pronoun YO:

Tener – to have, Yo tengo – I have

Venir – to come, Yo vengo – I come

Poner – to put, Yo pongo – I put

Suponer – to suppose, Yo supongo – I suppose

Proponer – to propose, Yo propongo – I propose

Verbs with stem change

There are plenty of irregular verbs that have a change in stem in present tense. These changes are: E – IE, U – UE, O – UE, E-I. They are applied for all pronouns apart from nosotros and vosotros.

Tener – to have. This verb has -NER, so the conjugation with YO will be “TENGO” instead of tieno, and E-IE change in stem (apart from Nosotros and Vosotros as it was said before).

Yo tengoI have (own form with yo)
Tú tienesYou have
Él, ella, usted tieneHe, she, you have
