Other irregular verbs

hacer (to do, make)

The stem is hic– and it takes the above endings. But in the 3rd person singular, what would be "hico" becomes hizo, changing c to z to maintain the same pronunciation as in the other conjugations.


decir (to say) | traer (to bring)

The stems are dij– and traj– and they take the endings as above except in the 3rd person plural, which loses the "i":

dije   traje
dijiste   trajiste
dijo   trajo
dijimos   trajimos
dijisteis   trajisteis
dijeron   trajeron

Verbs that end in –ducir follow the above pattern with the stem *duj-. For eample, producir (to produce):

di   vi
diste   viste
dio   vio
dimos   vimos
disteis   visteis
dieron   vieron
