28. Irregular Verbs in the Past — Part 2
Source: video
Part 2 finishes the irregular preterites: a few one-off "miscellaneous" verbs (caber, poder, saber, querer), the ver/dar pair, the stem-changing -ir verbs that change only in the third person, the y-insertion verbs (leer, creer, oír), and the yo-only spelling changes for -car, -gar, -zar verbs.
Key Rules
Caber → cupe, poder → pude, saber → supe, querer → quise — all share the same irregular pattern as Part 1.
Ver and dar use the regular -er/-ir preterite endings but without accents: vi, viste, vio… and di, diste, dio….
- Stem-changing
-ir verbs (sentir, pedir, dormir…) keep regular endings but change e→i or o→u only in él/ella and ellos.
Leer, creer, oír insert a y in the él/ellos forms and require accents on most other forms (to keep two adjacent vowels pronounced separately).
- Yo-only spelling changes:
-car → -qué, -gar → -gué, -zar → -cé.

Notes & Gotchas
Saber in the preterite (supe) often means "I found out" rather than "I knew."
Querer in the preterite (quise) implies the wanting is over; no quise = "I refused."
Poder in the preterite (pude) = "I managed to" / "I could (and did)." Don't confuse with the conditional podría ("I could / would be able to").
- The 3rd-person stem changes for
-ir verbs in preterite mirror the same letter changes seen in present tense (pedir → pide → pidió).
- The yo spelling changes (
-qué, -gué, -cé) preserve the consonant sound of the infinitive.
