In past-time Spanish, empezar becomes forms like empecé, empezaba, and he empezado depending on whether the start was completed, ongoing, repeated, or tied to now.
Empezar means “to begin” or “to start.” You’ll use it for classes, projects, jobs, habits, meetings, and stories. Past tenses are where people trip, mostly for two reasons: picking the wrong tense, and missing one spelling change.
This article fixes both. You’ll learn which past tense fits your meaning, how each form looks, and how to build sentences that don’t feel translated.
What Empezar Means In Everyday Spanish
Empezar points to the first moment of something. It works with nouns and with verbs.
- Empezar + noun: Empezamos la clase. (We started class.)
- Empezar a + infinitive: Empecé a estudiar. (I started to study.)
When you move into the past, Spanish asks what kind of “start” you mean: one completed starting point, a routine, a background action, or a start that matters now.
Empezar Past Tense Conjugation Basics In Spanish
This section uses the exact keyword once. Now let’s set your foundation: preterite for a finished starting point, imperfect for routine or background, plus a few compound past forms that show sequence.
Preterite: A Finished Starting Point
Use the preterite when “starting” is treated as a completed event on your timeline. The larger action can keep going, yet the start itself is a completed moment.
- Empecé a trabajar a las ocho. (I started working at eight.)
- La reunión empezó tarde. (The meeting started late.)
- Empezamos el proyecto en enero. (We started the project in January.)
One spelling change appears here: z → c in the yo form: empecé. The rest of the preterite keeps z.
Imperfect: Routine, Background, Or A Start In Progress
Use the imperfect when you describe what used to happen, what was going on, or a start that was unfolding as background. The start is not treated as one completed point.
- Cuando era niño, empezaba las tareas después de cenar. (I used to start homework after dinner.)
- Yo empezaba a entender el tema. (I was starting to understand the topic.)
- Siempre empezábamos con un repaso corto. (We always started with a short review.)
In the imperfect, empezar is regular. No spelling change shows up.

Past Forms That Add Timing And Sequence
Spanish has more than two ways to talk about the past. These come up all the time in school writing and real conversation.
Present Perfect: A Start Connected To Now
Use he empezado when the start matters now, or when the time period is still open.
- He empezado un curso nuevo esta semana. (I’ve started a new course this week.)
- Hemos empezado a preparar el examen. (We’ve started preparing for the exam.)
Past Perfect: A Start Before Another Past Moment
Use había empezado to place the start earlier than a later past action.
- Cuando llegaste, yo había empezado la presentación. (When you arrived, I had started the presentation.)
- Ellos habían empezado a salir juntos antes del verano. (They had started dating before summer.)
Progressive: A Start Happening In The Moment
To show “was starting” as an in-the-moment action, Spanish often uses estar + gerund: estaba empezando.
- Yo estaba empezando a sentirme mejor. (I was starting to feel better.)
- La clase estaba empezando cuando sonó el teléfono. (Class was starting when the phone rang.)
Empezar Past Tense Conjugation With Meaning Shifts
This heading uses the exact keyword a second time, in a natural way. Now use this idea: English often says “started” without telling you what kind of past you mean. Spanish makes you choose, and that choice changes how your sentence lands.
Table Of Past Forms And When They Fit
Use this table to pick a tense based on meaning. It’s broad on purpose, so you can match what you want to say without guessing.
| Form You Use | What It Communicates | Sentence Pattern |
|---|---|---|
| empecé (preterite yo) | A completed starting point | Empecé a + infinitive |
| empezó (preterite él/ella) | One start that moves the story forward | Empezó + noun |
| empezaron (preterite ellos) | A completed start by a group | Empezaron a + infinitive |
| empezaba (imperfect) | Routine or background; not a single completed point | Empezaba + noun / a + infinitive |
| empezábamos (imperfect nosotros) | Repeated habit in the past | Siempre empezábamos con… |
| he empezado | Start tied to now or an open time period | He empezado + noun |
| había empezado | Start that happened earlier than another past event | Ya había empezado + noun |
| estaba empezando | Start happening in the moment | Estaba empezando a + infinitive |
The One Spelling Change: Empecé
The preterite yo form is empecé, not empezé. Spanish spelling keeps sounds consistent, so z changes to c before é.
That change stays only in yo preterite. You still write empezaste, empezó, and empezaron.

How To Choose Preterite Vs Imperfect With Empezar

Table Of Common Mistakes And Clean Fixes
These are the errors that show up in writing and speech. Fix them and your Spanish sounds steadier right away.
| Mistake | Why It Happens | Fix |
|---|---|---|
| empezé | Missing the z → c change in preterite yo | empecé |
| Preterite used for habits | English “started” can hide repeated meaning | empezaba / empezábamos |
| empezaba used with a single time stamp | Imperfect turns the start into background | empecé / empezó |
| Missing a before an infinitive | English doesn’t use the connector | empezar a + infinitive |
| Using ya in every sentence | It can feel heavy when “already” doesn’t matter | Use ya only when timing needs it |
| Mixing empezar and comenzar in one paragraph | Both mean “to begin,” yet switching can feel choppy | Pick one per paragraph |
Accent Marks You Should Not Skip
Empecé has an accent on the last é. Empezó has an accent on the last ó. Those marks show stress and keep your writing correct.
If accents slow you down, type the word once with the accent, then copy it when you need it during practice. Repetition builds the habit.
Self-Check Before You Submit Writing Or Speak
- Preterite for a completed start, imperfect for routine or background.
- empecé with c and the accent mark.
- empezar a stays together before an infinitive.
- Time words match the tense you chose (ayer, cada día, esta semana, antes, mientras).
Three Lines To Memorize
These patterns let you produce dozens of sentences without stopping to think about structure.
- Empecé a + infinitive. (I started to…)
- Empezaba a + infinitive. (I was starting to… / I used to start to…)
- Había empezado a + infinitive. (I had started to…)
