Preterite vs imperfect: the Spanish past tenses made easy

You've got the present tense under control. You can talk about your job, your city and your weekend plans. Then someone asks you what you did last summer, and suddenly Spanish hands you not one past tense but two. Preterite vs imperfect: which one do you use?

This is the point where a lot of A2 learners slow down, and I completely understand why. English mostly gets by with one simple past ("I went", "I ate"), so having to choose feels strange. But here's a secret that makes it much easier for us: Hindi already makes the same choice. You just never had to think about it.

In this post I'll give you the core idea, a Hindi trick that does half the work for you, the forms of both tenses (with vosotrosyou allThe informal plural, used in Spain.), the trigger words, the verbs that change meaning, and a quiz at the end. ¡Vamos!Let's go!Used to cheer someone on or get moving.

Preterite vs imperfect: the one-line rule

Keep this in your head:

The preterite tells you what happened. The imperfect tells you what was going on.

The preterite, el pretérito indefinidothe preteriteThe name used in Spain for this past tense., is for finished actions with a clear start or end. Think of it as a photo: one moment, done.

The imperfect, el pretérito imperfectothe imperfectThe past tense for background and habits., is for the background: what things were like, what used to happen, what was in progress. Think of it as a video playing in the background, with no clear end.

• Ayer comí paella.Yesterday I ate paella.One finished action, so preterite. It happened, it's over.
• De niño, Pablo comía paella los domingos.As a boy, Pablo used to eat paella on Sundays.A past habit, so imperfect. It was a regular thing, with no single moment.

The Hindi trick: गया vs जाता था

This is my favourite way to explain it to Hindi speakers, because you already have the feeling for it.

• "मैं कल बाज़ार गया" (I went to the market yesterday) is one finished trip. In Spanish that's the preterite: Ayer fui al mercado.Yesterday I went to the market.One trip, finished, so preterite.
• "मैं हर रविवार बाज़ार जाता था" (I used to go to the market every Sunday) is a habit. In Spanish that's the imperfect: Iba al mercado cada domingo.I used to go to the market every Sunday.A past habit, so imperfect.
• "मैं खाना खा रहा था" (I was eating) is an action in progress. That's the imperfect too: Comía.I was eating.An action in progress, so imperfect. (Or estaba comiendoI was eatingEstar in the imperfect plus the -ing form., which is even closer to खा रहा था.)

How to form the preterite

Regular verbs

Take off -ar, -er or -ir and add these endings. Notice that -er and -ir verbs share exactly the same set.

Watch the accents on the "I" and "he/she" forms. HabléI spokePreterite, stress on the end. and hablóhe or she spokePreterite, stress on the end. are stressed on the last syllable. Without the accent, habloI speakPresent tense, stress on HA. is the present tense! Also notice that the "we" form for -ar and -ir verbs (hablamoswe speak or we spokeSame in present and preterite., vivimoswe live or we livedSame in present and preterite.) looks the same in both tenses. Context tells you which one it is.

The irregulars you'll use every day

A handful of very common verbs are irregular in the preterite. These are the ones to learn first:

Yes, serTo be (permanent)For what something is: identity, origin, profession. and irto goAn irregular verb. share the same preterite forms. FuiI was or I wentPreterite of both ser and ir. can mean "I was" or "I went", and the sentence makes it clear: Fui a Madrid.I went to Madrid.Ir, because of "a Madrid". vs Fue un día increíble.It was an amazing day.Ser, describing the day as a whole.

How to form the imperfect

Good news: the imperfect is one of the most regular tenses in Spanish.

Only three verbs are irregular in the imperfect, and that's the full list:

Notice that the "I" and "he/she" forms are identical in the imperfect (yo hablabaI used to speakImperfect, yo form., ella hablabashe used to speakImperfect, same form.). When it isn't clear from context, Spanish speakers simply add the pronoun.

When to use the preterite

Use the preterite for:

1. A single finished action. Anoche vi una película.Last night I watched a film.One finished action.
2. A series of actions, one after another. Me levanté, me duché y salí.I got up, showered and went out.A sequence of finished steps. Each action pushes the story forward.
3. An action with a clear time limit. Viví en Pune tres años.I lived in Pune for three years.A closed period, so preterite. Even though three years is long, it's a closed box: it started and it ended.
4. The action that interrupts. More on this one below.

Trigger words for the preterite

These words often point to a finished moment:

• ayeryesterdayUsually takes the preterite., anochelast nightUsually takes the preterite., anteayerthe day before yesterdayUsually takes the preterite.
• el año pasadolast yearA finished period., la semana pasadalast weekA finished period.
• una vezonceA single time., de repentesuddenlySomething happened at one moment.
• en 2019in 2019A specific date.

When to use the imperfect

Use the imperfect for:

1. Habits and repeated actions in the past. Cuando era pequeño, jugaba al críquet.When I was little, I used to play cricket.A habit, so imperfect.
2. Descriptions and background. Hacía calor y el cielo estaba azul.It was hot and the sky was blue.Setting the scene.
3. Age, time and feelings in the past. Tenía diez años.I was ten years old.Age takes the imperfect. Eran las ocho.It was eight o'clock.Time in the past takes the imperfect. Estaba nerviosa.I was nervous.A feeling, so imperfect.
4. Actions in progress. Leía el periódico.I was reading the newspaper.In progress, so imperfect.

Trigger words for the imperfect

• siemprealwaysOften takes the imperfect for past habits., a menudooftenA repeated action., a vecessometimesA repeated action.
• todos los díasevery dayA habit., cada veranoevery summerA habit.
• de niñoas a childChildhood habits., cuando era jovenwhen I was youngBackground.
• mientraswhileTwo actions going on at once.

A word of caution: trigger words are hints, not laws. SiemprealwaysUsually imperfect, but not always. can go with the preterite when the period is closed: Siempre la quise.I always loved her.A whole closed period, seen as finished. Focus on the idea first, and use the trigger words as a helpful nudge.

The classic story: background vs interruption

Here's where the two tenses work as a team. In most stories, the imperfect sets the scene and the preterite drops something into it.

• Estaba en la ducha cuando sonó el teléfono.I was in the shower when the phone rang.Background imperfect, interruption preterite.
• Llovía mucho cuando llegamos.It was raining hard when we arrived.Background imperfect, action preterite.
• Mientras cocinaba, se fue la luz.While I was cooking, the power went out.The power cut interrupts the cooking.

Hindi works the same way: "मैं नहा रहा था जब फ़ोन बजा". The ongoing part (नहा रहा था) is the imperfect. The thing that suddenly happened (बजा) is the preterite.

When you tell a story in Spanish, picture a film. The imperfect is the background music and scenery. The preterite is the plot: the things that happen, one after another.

Verbs that change meaning in the past

A few verbs change their meaning slightly depending on which past tense you use. This is A2 to B1 territory, so don't worry if it takes a while to sink in.

• conocerto know a person, to meetChanges meaning in the past.: Conocí a Ana en 2020.I met Ana in 2020.Preterite: the moment you met. vs Conocía a Ana.I knew Ana.Imperfect: an ongoing acquaintance.
• saberto know a factChanges meaning in the past.: Supe la verdad.I found out the truth.Preterite: the moment of finding out. vs Sabía la verdad.I knew the truth.Imperfect: you already knew it.
• quererto wantChanges meaning in the past.: No quise ir.I refused to go.Preterite negative: a refusal. vs No quería ir.I didn't want to go.Imperfect: just a feeling.
• poderto be able toChanges meaning in the past.: Pude terminar.I managed to finish.Preterite: you did it. vs Podía terminar.I was able to finish.Imperfect: you had the ability, but did you?

The logic is the same as always. The preterite is the moment something happened. The imperfect is the ongoing situation.

A note for Spain: "today" uses a third past tense

If you spend time in Spain, you'll hear a lot of he comidoI have eatenThe present perfect. and hemos vistowe have seenThe present perfect.. In Spain, people usually use this present perfect, el pretérito perfectothe present perfectHaber plus a past participle., for things that happened today or in a time period that isn't over yet.

• Hoy he comido paella.Today I've eaten paella.Today, so present perfect in Spain.
• Ayer comí paella.Yesterday I ate paella.Yesterday, so preterite.

Many Latin American speakers would use the preterite for both. You don't need to master this right now. Just don't be surprised when you hear it, and stick to preterite vs imperfect for anything before today.

Common mistakes with the Spanish past tenses

Using the preterite for age and descriptions

"Tuve diez añosI had ten years (wrong here)Age in the past needs the imperfect." sounds natural if you think of English "I was ten", but age is background, so: Tenía diez años.I was ten years old.Age takes the imperfect.

Using the imperfect for a closed period

"Vivía en Delhi cinco añosI used to live in Delhi five years (awkward)A closed period needs the preterite." is a common slip. When you give the length of a finished period, use the preterite: Viví en Delhi cinco años.I lived in Delhi for five years.A closed period.

Dropping the accents

Comióhe atePreterite, stress on the end. vs comíahe was eatingImperfect, stress on the í. vs comoI eatPresent.. These three look close, but the accent changes the tense. Always write them, and say the stress clearly.

Trying to translate "was" and "were" directly

English "was" can be either tense. "It was a great party" (the party as a whole, finished) is Fue una fiesta genial.It was a great party.The whole event, so preterite. "The party was in a big house" (background description) is La fiesta era en una casa grande.The party was in a big house.Background, so imperfect. Think about the idea, not the English word.

A quick summary to save

• Preterite = what happened: finished actions, sequences, closed periods, interruptions. Like Hindi गया, खाया.
• Imperfect = what was going on: habits, descriptions, age, time, feelings, actions in progress. Like Hindi जाता था, खा रहा था.
• In a story, the imperfect is the scene and the preterite is the plot.
• Only serTo be (permanent)For what something is: identity, origin, profession., irto goIrregular in the imperfect. and verto seeIrregular in the imperfect. are irregular in the imperfect.
• Trigger words help, but the idea always wins.

Five questions. Think "photo or video?" before you pick.

Keep going

Preterite vs imperfect isn't something you "finish" learning in a day. It's a feeling that grows each time you tell a little story. Start small: tell yourself, in Spanish, what you did yesterday and what your childhood was like. If the present tense still feels shaky, revisit my guide to Spanish present tense regular verbs first, and when you're ready for the next challenge, look at por vs para.
