The preterite: key irregular verbs

🎬 The doodle video for this lesson is coming soon. Subscribe on YouTube to see it first.

Some of the most useful verbs are irregular in the preterite. A handful of them appear in almost every holiday description.

Ir and ser: identical

In the preterite, ir (to go) and ser (to be) have the same forms: fui, fuiste, fue, fuimos, fuisteis, fueron.
Context tells you which: Fui a España = I went to Spain. Fue divertido = It was fun.

Other key irregulars

Learn the yo and él forms first.

Using them

Hice turismo. = I went sightseeing.
Fue increíble. = It was incredible.
Vi muchos monumentos. = I saw lots of monuments.
Worked example

Translate: I went to Mexico and it was incredible.

  1. I went: ir → fui
  2. to Mexico = a México
  3. it was: ser → fue
  4. incredible = increíble

Answer: Fui a México y fue increíble.

Key idea

Ir and ser share preterite forms: fui, fuiste, fue, fuimos, fuisteis, fueron. Learn hice/hizo, tuve/tuvo, estuve/estuvo, vi/vio.
