Irregular PreteriteIt’s flipping hard!

Box A verbsIt includes the Preterite/Past Tense of 12 verbs: andar (to walk) anduv-, caber (to fit) cup-, decir (to say) dij-, estar (to be-temporary) estuv-, hacer (to do/make) hic-, poder (to be able to) pud-, poner (to put) pus-, querer (to want) quis-, saber ( to know) sup-, traer (to bring) traj-, tener (to have) tuv-, and venir (to come) vin-, as you can see they all have irregular stems. They use a combination of AR/ER/IR ending with NO ACCENT MARKS.

Box A verbsThe verb hacer which in the Preterite/Past Tense is hic- changes the “c” for a “z” in the él, ella. Ud. form.

We drop the letter “i” in (ellos/ellas/Uds.) –(i)eron for ther Preterite/Past of decir “dij-” and traer “traj-”.

Ex: Yo hice, but Ud. hizo

Ex: Ellos dijeron or trajeron
