The essential eight

Ser, estar, tener, ir, hacer, poder, querer and saber appear in virtually every exam task. Learn their present, preterite, future and conditional forms before anything else.

Present tense yo irregulars

Many key verbs have irregular yo forms only: tengo, hago, pongo, salgo, vengo, digo, sé, conozco. The other persons follow regular patterns.

Preterite irregular groups

Ser and ir share the same preterite (fui, fuiste, fue...). Tener, estar, poder, poner, saber and querer all follow the same preterite stem pattern: tuv-, estuv-, pud-, pus-, sup-, quis-.

Future irregular stems

Nine key verbs use shortened stems in the future and conditional: tendr-, vendr-, pondr-, saldr-, valdr-, podr-, querr-, sabr-, har-, dir-. The endings are always the same.

Memory strategy

Group verbs by their irregular pattern rather than memorising each separately. Once you know one verb in a group, the rest follow the same pattern.

Turn this into recall

Reading grammar explains the rules — but only active recall builds exam-ready memory. Practice typing these forms with instant feedback.
