Is it an important past tense? Heck, yes! You’ll need it if you want to talk about past actions. For this reason, in this guide, I’ll focus on providing you with crucial information about the preterite tense in Spanish.

As you may already know, the present tense has many stem-changing verbs in Spanish. Verbs with spelling changes in the present tense will also have changes in the preterite tense. 

Here are the verbs and the subject pronouns you need to watch out for:

  • First person singular (yo) 
    • Verbs that end in ‘-car’, ‘-gar’, ‘-zar’.
  • Third person singular and plural 

You can see the changes you have to make in the graphic below:

Take Note: Accent marks are key for the Spanish preterite conjugations. In writing situations, you only need to add the proper accent mark. However, when it comes to speaking, make sure to adjust your pronunciation. Check the examples below. 

Yo canto.
I sing.

Él cantó.
He sang.

Irregular verbs in the preterite tense

Unlike the imperfect tense in Spanish, the preterite has many irregular verbs. These irregular verbs have significant changes on their stems and they also use slightly different endings

With the exception of ser and ir, the endings for irregular verbs are:

SubjectIrregular ending
Yo-e
-iste
Él / Ella / Usted-o
Nosotros-imos
Vosotros-isteis
Ellos / Ellas / Ustedes-ieron

Irregular endings do not have an accent mark. Can you tell why? Because the irregularities of these verbs are more than enough to indicate that they are in the preterite form. 

Here are some patterns of irregular verbs in the Spanish preterite tense. 

Verbs with ‘uv’ in the stem

  • Estar – Estuv
  • Andar – Anduv
  • Tener – Tuv

Verbs with ‘u’ in the stem

  • Saber – Sup
  • Poder – Pud
  • Poner – Pus
  • Caber – Cup
  • Haber – Hub

Verbs with ‘i’ in the stem 

  • Hacer – Hic
  • Venir – Vin
  • Querer – Quis
  • Decir – Dij

Derivatives of ‘traer’ and verbs with a ‘-ducir’ suffix

  • Conducir – Conduj
  • Traducir – Traduj
  • Producir – Produj
  • Traer – Traj
  • Atraer – Atraj

So to conjugate these verbs, you can follow this formula:

[Irregular stem] + [irregular ending]

What did you guys do on Saturday?

Lo siento, tuve mucho trabajo.
I’m sorry, I had a lot of work.

Nosotros estuvimos enfermos.

Ser and ir are also irregular verbs. In fact, in the preterite tense, these verbs have the same conjugation. The context can help you tell which verb is being used. 

PersonSerIr
Yofuifui
fuistefuiste
Él / Ella / Ustedfuefue
Nosotrosfuimosfuimos
Vosotrosfuisteisfuisteis
Ellos / Ellas / Ustedesfueronfueron

Helen fue al cine.
Helen went to the movies.

Louise fue la mejor maestra que tuve.
Louise was the best teacher I ever had.

Take Note: Since they have the same conjugation, it can be hard to tell if we’re referring to ser or ir. However, unlike ‘ser’, ir is always followed by the preposition ‘a’ (to). This can be an easy and quick way to tell which verb is being used. 

When to Use the Spanish Preterite 

As a Spanish past tense, the preterite refers to past actions and events. However, this tense conveys that those actions ended or were completed at some point in the past. 

We use the preterite in Spanish to talk about:

  • Actions that were completed in the past.
  • Actions that began or lasted a specific period of time in the past.
  • Sequence of events or actions completed in the past.

Sentences in the preterite tense

Below I’ve provided examples to clarify and illustrate each of these uses for the preterite tense in Spanish and various situations in which you can use them.

Actions that occurred or began at a specific point in the past or lasted a specific amount of time

(Subject pronoun) + [Verb in the preterite]

I already washed and dried the dishes.

Mis vecinas pintaron y remodelaron su casa.

Take Note: In Spanish, ‘desayunar’ is a verb used to say ‘to eat breakfast’, which is why we don’t need to explicitly use ‘comer’.

Trigger Words for Preterite

Here is a table with some common time markers that work with the preterite tense:

SpanishEnglish
YaAlready
AyerYesterday
El año pasado*Last year
Hace*Ago
AnocheLast night
HoyToday
Esta mañanaThis morning
En ese momentoIn that moment
Una vez*One time
En 1950*In 1950
La semana pasadaLast week
El 8 de julio*On July 8
El otro díaThe other day

Some notes about these triggering words:

  • You can replace ‘año’ with months and days. Just make sure the article matches the gender of the noun you use. 
  • Hace’ needs to be followed by an amount of time. 
  • Una vez’ is a singular form. You can change the number in Spanish to say how many times an action happened (e.g. dos veces, tres veces, etc). 
  • All dates in Spanish are trigger words for the preterite. 

Keep in mind that trigger words are a great help, but they’re not mandatory. Additionally, since Spanish is so flexible, they can be placed before or after the verb in preterite. 

La semana pasada vi a Claudia.
I saw Claudia last week.

Lauren renunció hace tres años.
Lauren quit three years ago.

Hoy no fuimos a la oficina.
We didn’t go to the office today.

Take Note: Just like in English, hoy (today) can be a trigger word for the preterite tense. This is because some actions you did today are already finished. However, this use is more popular in Latin American Spanish. In Spain, you would use hoy with the present perfect tense

How to Tell When to Use Preterite or Imperfect in Spanish

The imperfect tense in Spanish is another past tense. This leads to a common question– how do you know if you have to use preterite or imperfect? 

Before I give you the explanation, check the examples below. 

Tip: don’t focus on the translation because it’s likely to be the same for both examples. Instead, focus on the Spanish sentences and check all the elements surrounding the verb. If you need help, jump to the graphic below. 

Cuando era niña, jugaba con mis hermanos.
When I was a kid, I played with my brothers.

Ayer jugué con mi hermanito.
Yesterday I played with my little brother.

Do you see the difference? 

We use imperfect tense to describe actions that we did frequently in the past. These can be habits or events that took place so often that we cannot tell the specific moment when they happened or how many times they happened.

Put another way to help you remember this rule, if we can’t perfectly point out a moment in time when the event or action took place, then it must be imperfect.

That’s the idea I’m delivering with example #1. Playing with my brothers was something I did frequently, so I cannot tell you a date or how many times we played together. 

On the contrary, the preterite in Spanish is way more specific. It tells you exactly when I played with my brother and it also implies how many times I did this action…at least just for yesterday! I’m a better sister than that! 

Hopefully, this graphic helps you see this distinction:

Key Points

When talking about the past, the Spanish preterite refers to complete past actions. Here are some rules and key points that you need to keep in mind:

  • We use the preterite tense to refer to:
    • Actions that have a clear ending or beginning.
    • A sequence of past actions. 
    • Actions that were clearly finished in the past. 
  • Some -IR stem changing verbs in the present tense also have spelling changes in the preterite. This change only affects the third person singular and plural. 
  • Verbs ending in -car, -gar and -zar have a consonant change when being conjugated to the first person singular. 
  • Irregular verbs in the preterite tense have major changes in their stem and their endings are slightly different from regular verbs. 
  • Trigger words for the preterite tense refer to a specific moment in time. 

We Spanish speakers also learn the preterite in school. But, why don’t we struggle with this tense like many Spanish learners do? Because we use it all the time by speaking the language! So, to master the preterite, you need to practice a lot! You can start by taking this conjugation preterite quiz.
