Ready for a blast from the past?
As you may know, Spanish has two past tenses: preterite and imperfect. It’s often tricky to know which to use when, since they both refer to actions in the past. Fortunately, several general guidelines exist to help you realize when to use preterite vs imperfect.
It’s also helpful to know which Spanish phrases trigger the use of either the preterite or the imperfect, so we’ll take a look at those later.

Preterite vs Imperfect Conjugation Rules
Preterite and Imperfect tenses are both related to the past, but they function differently.
The preterite tells you precisely when something happened in the past, while the imperfect tells you in general terms when an action took place with no definite ending.
Here’s a quick look at how to conjugate regular verbs in the preterite and imperfect forms.
(Be sure to check out our post on All You Ever Needed to Know About Spanish Simple Past Tense Verbs for a thorough rundown of both regular and irregular preterite verb conjugations.)
Preterite: Regular -ar Verbs
For example: hablar (to talk) becomes yo hablé, tú hablaste, él/ella/Ud. habló, nosotros hablamos, and ellos/Uds. hablaron
Preterite: Regular -er and -ir Verbs
Correr (to run): corrí, corriste, corrió, corrimos, corrieron
Abrir (to open): abrí, abriste, abrió, abrimos, abrieron
Imperfect: Regular -ar Verbs
So, hablar in this form becomes hablaba, hablabas, hablaba, hablábamos, hablaban.
Imperfect: Regular -er and -ir Verbs
Correr (to run): corría, corrías, corría, corríamos, corrían
Abrir (to open): abría, abrías, abría, abríamos, abrían
Phrases that Trigger the Preterite
A handful of words and phrases indicate specific time frames that signal the use of the preterite (vs imperfect). Let’s take a look at some of them!
una vez – one time/once
el otro día – the other day
ayer – yesterday
anoche – last night
la semana pasada – last week
el mes pasado – last month
el año pasado – last year
en ese momento – at that moment
durante (cinco) siglos – for (five) centuries
desde el primer momento – from the first moment
ayer por la tarde – yesterday afternoon
hoy por la mañana – this morning
hace (diez) años – (ten) years ago
hace (tres) días – (three) days ago
Verbs that (Almost) Always Use the Preterite
Furthermore, verbs used to discuss events with a certain beginning and end are almost always used in the preterite. Por ejemplo:
casarse – to marry
graduarse – to graduate
cumplir años – to have a birthday
llegar – to arrive
darse cuenta de – to realize
morir – to die
decidir – to decide
nacer – to be born
descubrir – to discover
salir – to leave

El Preterito Imperfecto
On the other hand, you’ll be using the imperfect tense to talk about past actions without a definite end. Perhaps they are yet to be completed or they refer to a general time in the past. The imperfect form is typically used for: habitually repeated actions; time and dates; someone’s age in the past; characteristics; and mental or physical states.
Phrases that Trigger the Imperfect
Lucky for you, there are also a bunch of words and phrases that tend to signal that a verb should be used in the imperfect!
a menudo – often
frecuentemente – frequently
rara vez – rarely
a veces – sometimes
generalmente – usually
siempre – always
algunas veces – at times
mientras – while
todos los años – every year
cada día – every day
muchas veces – many times
todo el tiempo – all the time
con frecuencia – frequently
casi nunca – almost never
por lo general – generally
todos los días – every day
de vez en cuando – once in a while
por un rato – for a while
en aquella época – at that time

Preterite vs Imperfect Examples
These past tense forms are often used to talk about an ongoing action or event that was interrupted. Here, the interrupted action uses the imperfect tense, while the interrupting action uses the preterite.
Caminaba a la biblioteca cuando me encontré con el amor de mi vida.
I was walking to the library when I met the love of my life.
Juana y Alberto hablaban de la reunión cuando llegué a la oficina.
Juana and Alberto were talking about the meeting when I got to the office.
Preterite vs Imperfect Statements
The rule of thumb for determining which tense to use is that the preterite talks about what you did, and the imperfect talks about what you were doing or what you used to do. Notice how the meaning changes for these verbs in the preterite vs the imperfect.

I met the president of the organization.
|Conocía al presidente de la organización.|
I knew the president of the organization.
|Ya supieron del concierto.|
