Preterite vs Imperfect in Spanish

Spanish divides the past tense into two forms: preterite vs imperfect. These forms show past actions from different perspectives: the imperfect describes ongoing or recurrent actions, while the preterite talks about completed ones. To properly use the language, it’s crucial to comprehend the distinctions between these tenses. Hence, this article will help you understand preterite and imperfect forms, their specific uses, and ways to distinguish between them.

Understanding the Basics: Imperfect vs Preterite

Spanish, a language rich in nuances, treats the past carefully, dividing it into two distinct tenses. This distinction, unique and vital to the language’s structure, allows speakers to convey past actions from different angles. So, we will look at the difference between preterite and imperfect.

The preterite is the go-to tense for completed actions. It answers the question, ‘What happened?’ Imagine a specific event, like a concert. You’d say, Fui al concierto [fwi al kon’sjeɾto] (I went to the concert). This sentence implies a clear, finite action. The preterite captures moments in time, offering a clear start and end. It’s straightforward and factual, focusing on the main events and actions.

The imperfect, however, deals with ongoing or habitual actions in the past. It’s like a backdrop, providing context or describing conditions. When you say, Iba al parque cada sábado [’iba al ‘paɾke ‘kaða sa’βaðo] (I used to go to the park every Saturday), you’re not focusing on a single event but a recurring activity. The imperfect paints a picture of continuous or repeated actions without a definite endpoint. It’s about setting the scene or describing regular habits.

When to Use Preterite vs Imperfect: Key Situations

Understanding when to use these tenses is crucial for accurately conveying past actions in Spanish. Below, we delve into specific situations where each is the appropriate choice.

When to Use the Past Imperfect Tense

Talking about imperfect vs preterite rules, the first one is used for various situations that emphasize ongoing actions or states in the past rather than specific events or actions with a clear end. Here are key instances when it is most appropriately used:

  • Past actions without a defined end. This is for actions that were ongoing or had no specific conclusion.

Los niños jugaban en el parque. [los ˈniɲos xuˈɣaβan en el ˈpaɾke] (The children were playing in the park.)

  • Describing people, things, places, and situations in the past. The imperfect is ideal for setting a scene or describing characteristics from the past.

El cielo estaba nublado. [el ˈθjelo esˈtaβa nuˈβlaðo] (The sky was cloudy.)

  • To set the stage for another past action. Often used with estar plus gerund, it sets up a background for an action that interrupts, usually expressed in the preterite.

Estábamos cenando cuando sonó el timbre. [esˈtaβamos θeˈnando ˈkwando soˈno el ˈtimbɾe] (We were having dinner when the doorbell rang.)

  • Repeated or habitual actions in the past. The imperfect captures actions that were regular or habitual in someone’s past.

Cada verano íbamos a la playa. [ˈkaða βeˈɾano ˈiβamos a la ˈplaʝa] (Every summer we used to go to the beach.)

  • Talking about someone’s age in the past. For discussing ages in past contexts, the imperfect tense is often used.

Cuando tenía ocho años, aprendía a nadar. [ˈkwando ˈtenia ˈotʃo ˈaɲos, apɾenˈðia a naˈðaɾ] (When I was eight years old, I was learning to swim.)

  • Telling the time or talking about time in the past. The imperfect is the right choice when indicating the time in a past context.

Eran las tres de la tarde y hacía calor. [eˈɾan las ˈtɾes ðe la ˈtaɾðe i aˈθia kaˈloɾ] (It was three in the afternoon, and it was hot.)

Era muy tarde cuando volví a casa. [ˈeɾa mwi ˈtaɾðe ˈkwando bolˈβi a ˈkasa] (It was very late when I came back home.)

Imperfect Trigger Words

In Spanish, certain words and phrases signal the use of the past imperfect tense. They often indicate habitual actions, ongoing states, or general conditions in the past:

  • Cada [ˈkaða] + [time period] – every [time period]

Cada invierno íbamos a esquiar. [ˈkaða inˈβjeɾno ˈiβamos a esˈkjaɾ] (Every winter we used to go skiing.)

  • Algunas veces [alˈɣunas ˈβeθes] – at times

Algunas veces olvidaba hacer los deberes. [alˈɣunas ˈβeθes olβiˈðaβa aˈθeɾ los ðeˈβeɾes] (At times I forgot to do the homework.)

  • A veces [a ˈβeθes] – sometimes

A veces caminábamos bajo la lluvia. [a ˈβeθes kaminˈaβamos ˈβaxo la ˈʎuβja] (Sometimes we walked in the rain.)

  • Con frecuencia [kon freˈkwenθja] / frecuentemente [frekwenˈtemente] – frequently

Frecuentemente volvía a casa tarde. [frekwenˈtemente bolˈβia a ˈkasa ˈtaɾðe] (I frequently came back home late.)

  • A menudo [a ˈmenuðo] – often

De pequeño comía helado muy a menudo. [de peˈkeɲo ˈkomia eˈlaðo mwi a ˈmenuðo] (I often ate ice cream when I was a child.)

  • Todos [ˈtoðos] + [time period] – every [time period]

De pequeño iba a la escuela todos los días. [de peˈkeɲo ˈiβa a la esˈkwela ˈtoðos los ˈdias] (I used to go to school every day when I was a child.)

  • Casi nunca [ˈkasi ˈnweβa] – almost never

Casi nunca tenía dinero. [ˈkasi ˈnweβa ˈtenia ðiˈneɾo] (I almost never had any money.)

  • Muchas veces [ˈmutʃas ˈβeθes] – many times

Muchas veces no sabía qué responder. [ˈmutʃas ˈβeθes no saˈβia ke resˈponðeɾ] (Many times I didn’t know what to answer.)

  • Mientras [ˈmjentɾas] – while

Tú estudiabas mientras yo limpiaba. [tu esˈtuðjaβas ˈmjentɾas ʝo limˈpjaβa] (You were studying while I was cleaning.)

  • En aquel tiempo [en aˈkel ˈtjempo] / en aquella época [en aˈkeʎa ˈepoka] – at that time

Era muy buen estudiante en aquel tiempo. [ˈeɾa mwi ˈβwen esˈtuðjante en aˈkel ˈtjempo] (I was a very good student at that time.)


When to Use the Preterite Tense

Here are some critical situations where uses of preterite vs imperfect emerge: the preterite is usually the ideal choice for events with clear boundaries. It’s about pinpointing moments or events that are completed without lingering effects in the present. Here are some key scenarios:

  • One-time events and completed actions with specific timing. This usage is for events that started and finished at a particular time. 

Mi hermano volvió a las 8. [mi eɾˈmano βolˈβjo a las oʧo] (My brother came back at 8:00.)

Ayer comí manzanas. [ajeɾ koˈmi manˈθanas] (I ate some apples yesterday.)

  • Actions completed a specific number of times or during a certain period. When actions occur a certain number of times or within a defined timeframe, the preterite is your go-to.

Anoche me desperté dos veces. [aˈnoʧe me ðespeɾˈte ˈdos ˈβeses] (I woke up twice last night.)

  • Specific period actions no longer occurring. The preterite helps talk about actions confined to a particular period, no longer happening.

Viví en Barcelona durante siete meses. [biˈβi en baɾθeˈlona ðuˈɾante ˈsjete ˈmeses] (I lived in Barcelona for seven months.)

  • Describing situational changes. The tense is useful for narrating sudden shifts in situations, especially when contrasted with the ongoing state expressed in the imperfect. It highlights a specific point of change.

No quería tener hijos pero de un día para el otro cambié de opinión. [no keˈɾia ˈteneɾ ˈixos ˈpeɾo ðe un ˈdia ˈpaɾa el ˈotɾo kamˈbje ðe oˈpinjon] (I did not want to have children, but I changed my mind overnight.)

  • When describing actions that were part of a chain of events. It is ideal for listing actions in a sequence, each completed before the next began.

Abrió la carta, la leyó y la tiró a la basura. [aˈβɾjo la ˈkaɾta la leˈʝo i la tiˈɾo a la βaˈsuɾa] (He opened the letter, read it, and threw it into the trash.)

Phrases that Trigger the Preterite

Certain words and phrases in Spanish act as triggers, indicating that the preterite tense is appropriate. They are generally tied to specific time frames or moments in the past and emphasize the completion of an action:

  • Ayer [ˈaʝeɾ] – yesterday

Ayer hizo mucho frío. [ˈaʝeɾ ˈiθo ˈmutʃo ˈfɾio] (It was very cold yesterday.)

  • Anteayer [anteˈaʝeɾ] – the day before yesterday

Terminé el curso anteayer. [teɾmiˈne el ˈkurso anteˈaʝeɾ] (I finished the course the day before yesterday.)

  • Anoche [aˈnotʃe] – last night

Anoche me fui a la cama muy tarde. [aˈnoʧe me ˈfwi a la ˈkama ˈmwi ˈtaɾðe] (I went to bed very late last night.)

  • Entonces [enˈtonθes] – then

No supe qué decir entonces. [no ˈsupe ke ðeˈθiɾ enˈtonθes] (I did not know what to say then.)

  • Desde el primer momento [ˈðezðe el ˈpɾimeɾ moˈmento] – from the first moment

Te amé desde el primer momento. [te aˈme ˈðezðe el ˈpɾimeɾ moˈmento] (I loved you from the first moment.)

  • De repente [de reˈpente] – suddenly

  • El otro día [el ˈotɾo ˈðia] – the other day

Lo vi el otro día. [lo ˈβi el ˈotɾo ˈðia] (I saw him the other day.)

  • Durante + [period of time] [duˈɾante] – for [period of time]

Conjugation Patterns: Imperfect vs Preterite Spanish

Understanding the conjugation patterns of the imperfect and preterite in Spanish is essential for accurately expressing past actions. Here, we’ll explore the conjugation patterns for both tenses, providing a clearer understanding of their differences and applications.

Past Imperfect Tense Conjugations

The past imperfect tense in Spanish has a straightforward set of endings for regular verbs and only a few irregular verbs. Here’s how they are conjugated.

Pronoun-ar conjugation (hablar)-er conjugation (comer)-ir conjugation (vivir)
Yohablaba (I was speaking)comía (I was eating)vivía (I was living)
hablabas (You were speaking)comías (You were eating)vivías (You were living)
Él/ella/ustedhablaba (He/She/You was speaking)comía (He/She/You was eating)vivía (He/She/You was living)
Nosotros/ashablábamos (We were speaking)comíamos (We were eating)vivíamos (We were living)
Vosotros/ashablabais (You all were speaking)comíais (You all were eating)vivíais (You all were living)
Ellos/ellas/ustedeshablaban (They/You all were speaking)comían (They/You all were eating)vivían (They/You all were living)

There are only three irregular verbs in the imperfect tense: ser [sɛɾ] (to be)ir [iɾ] (to go), and ver [beɾ] (to see). Their conjugations are unique and should be memorized:

PronounSer (to be)Ir (to go)Ver (to see)
Yoera (I was)iba (I went)veía (I saw)
eras (You were)ibas (You went)veías (You saw)
Él/ella/ustedera (He/She/You was)iba (He/She/You went)veía (He/She/You saw)
Nosotros/aséramos (We were)íbamos (We went)veíamos (We saw)
Vosotros/aserais (You all were)ibais (You all went)veíais (You all saw)
Ellos/ellas/ustedeseran (They/You all were)iban (They/You all went)veían (They/You all saw)

Preterite Tense Conjugations

When talking about imperfect vs preterite conjugations, the second one is often a bit trickier for learners due to its irregular verbs. Let’s break down the conjugation patterns for regular and irregular verbs.

Regular verbs in this past tense follow consistent patterns, making them easier to memorize. Like in the present tense, there are -ar, -er, and -ir verbs. Here’s an overview:

Pronoun-ar Conjugation (Hablar)-ar conjugation (Comer)-ir conjugation (Vivir)
Yohablé (I spoke)comí (I ate)viví (I lived)
hablaste (You spoke)comiste (You ate)viviste (You lived)
Él/ella/ustedhabló (He/She/You spoke)comió (He/She/You ate)vivió (He/She/You lived)
Nosotros/ashablamos (We spoke)comimos (We ate)vivimos (We lived)
Vosotros/ashablasteis (You all spoke)comisteis (You all ate)vivisteis (You all lived)
Ellos/ellas/ustedeshablaron (They/You all spoke)comieron (They/You all ate)vivieron (They/You all lived)

Irregular verbs in the preterite can be more challenging due to changes in stems or endings. There are several groups of these verbs, and each group has its unique alteration in conjugation:

  • Traer, decir, and -ucir verbs
PronounConjugation (Traer)
Yotraje (I brought)
trajiste (You brought)
Él/ella/ustedtrajo (He/She/You brought)
Nosotros/astrajimos (We brought)
Vosotros/astrajisteis (You all brought)
Ellos/ellas/ustedestrajeron (They/You all brought)
  • Verbs with stem changes. These verbs change their stem in the preterite but keep regular endings. Examples include andar (anduv-), poner (pus-), hacer (hic-/hiz-), etc.
PronounConjugation (Hacer)
Yohice (I did/made)
hiciste (You did/made)
Él/ella/ustedhizo (He/She/You did/made)
Nosotros/ashicimos (We did/made)
Vosotros/ashicisteis (You all did/made)
Ellos/ellas/ustedeshicieron (They/You all did/made)
  • Ser and ir
PronounConjugation (Ser/Ir)
Yofui (I was/went)
fuiste (You were/went)
Él/ella/ustedfue (He/She/You was/went)
Nosotros/asfuimos (We were/went)
Vosotros/asfuisteis (You all were/went)

The preterite is used for specific, completed actions, while the imperfect describes ongoing or habitual past activities. Regular verbs follow predictable conjugation patterns in both tenses, but certain irregular verbs require special attention. Understanding trigger words and the context, along with regular practice, will enhance your Spanish proficiency and ability to share and understand past experiences.


Are there any tricks to remember the irregular verbs in the preterite tense?

Creating mnemonics can be a helpful way to remember irregular verbs. Grouping them by their irregular patterns and associating them with a memorable phrase, song, or image can make recall easier. Additionally, regular practice and repetition through flashcards or apps can reinforce your memory of these verbs.

What common mistakes should I avoid when using preterite and imperfect tenses?

A common mistake is overusing the preterite for ongoing or habitual actions, which should use the imperfect. Also, confusing irregular verb conjugations is frequent. Practice with examples and pay attention to the context of the action to avoid these errors.

Can watching Spanish movies or TV shows help in understanding these tenses?

Absolutely! Watching media in Spanish can significantly improve your understanding of how these tenses are used in everyday language. It provides context and helps you hear how native speakers naturally switch between tenses in conversation. Subtitled content can be beneficial for learners.
