Essential irregular verbs in the Spanish preterite tense: your guide to conversation

As you can see in the examples above, even the most basic actions—seeing, eating, and being—can involve irregular forms. If you want to sound natural and be understood when sharing your travel stories, you have to get comfortable with these essential irregular verbs.

Example in context:

Imagine you are talking about your time in Spain.

Because the verb ir almost always requires a preposition like a (to), it is usually easy to tell the difference. If fui is followed by a location, it means “went.” If it is followed by an adjective or noun, it means “was.”

Notice the change from hiciste to hizo. This spelling change is important because if we wrote hice with a ‘c’ for the third person singular, it would sound like hice-o, which is not correct. The ‘z’ maintains the correct ‘s’ sound.

Cultural example (Cuba):

“Mi amigo hizo una reserva para la cena en La Habana Vieja.” (My friend made a reservation for dinner in Old Havana.)

Let us look at two of the most frequently used verbs in this group: tener and poder.

Example: “Nosotros tuvimos una gran oportunidad de conocer gente local en Guayaquil.” (We had a great opportunity to meet local people in Guayaquil.)

Example: “Yo no pude encontrar un taxi después del concierto.” (I could not find a taxi after the concert.)

Remember that the stems of estar (estuv-) and saber (sup-) follow the exact same ending pattern. If you learn the endings, you just need to memorize the stem change for each verb.

You already saw hacer (hic-) earlier, which also falls into this I-stem category.

Example: “Ella no quiso ir al museo, así que fuimos a un parque.” (She refused to go to the museum, so we went to a park.)

Example: “Tú viniste a mi casa justo a tiempo para la fiesta.” (You came to my house just in time for the party.)

The trick here is that because the stem already ends in a ‘j’ sound, we drop the ‘i’ from the ieron ending. The ending becomes -eron.

Example (Ecuador): “Los guías nos dijeron que la mejor época para visitar las Galápagos es en invierno.” (The guides told us that the best time to visit the Galápagos is in winter.)

If you look closely at the table, you can see that the stem dij- is used throughout, but the ending for the plural ellos/ellas/ustedes is eron, not ieron. This is a must-know rule for all J-stem verbs like traer (trajimos, trajeron) and conducir (condujimos, condujeron).

Example: “Yo vi el atardecer más hermoso desde el Morro en Cuba.” (I saw the most beautiful sunset from the Morro in Cuba.)

Example: “Mi tía me dio un regalo cuando llegué a casa.” (My aunt gave me a gift when I arrived home.)

If you are talking about travel logistics, caber might come up: “Mi maleta no cupo en el compartimento superior.” (My suitcase did not fit in the overhead compartment.)

Notice how the combination of hacer (hice) and ser (fue) creates a smooth narrative flow.

The ability to use puso and dio allows you to describe specific actions related to cooking and flavor, which is a major part of Cuban culture.

Using vimos and pudimos naturally conveys the success of your observations, while vino and quiso help you talk about the guide’s past decisions.

These simple associations can make recall faster when you are speaking quickly.

If you are talking about a specific, finished moment (like a traveler describing an arrival or a single historical event), the preterite is the correct choice.
