Questions about the Preterite
Q: Why is it eu fiz and NOT eu fizé?
Regular -ar verbs have an accent in the eu form (falei), but irregular verbs do not follow this pattern. The verb fazer is irregular (fiz), so no accent is used.
Q: Why is it ela quis and NOT ela queriu?
The verb querer is irregular in the preterite and uses the stem quis- (quis, quiseste, quis, quisemos, quiseram).
Q: Why is it eu paguei and NOT eu pagé?
Verbs ending in -gar insert a u in the eu form of the preterite to preserve pronunciation:
pagar → paguei (not pagé).
Q: Why is it eles leram and NOT eles leieram?
In Portuguese, verbs like ler and crer form the preterite regularly (li, leu, leram). The -yeron pattern seen in Spanish does not exist in Portuguese.
