How to Say "to start" in Spanish
The most common Spanish word for “to start” is “comenzar” — use this general verb for starting almost any action, activity, or event, especially in formal contexts..
comenzar
koh-men-SAR/ko.menˈsaɾ/

Examples
Comenzamos el proyecto la próxima semana.
We start the project next week.
Comienzo mi dieta el lunes.
I start my diet on Monday.
¿A qué hora comienza la película?
What time does the movie start?
Ellos comenzaron a estudiar después de la cena.
They began to study after dinner.
The E > IE Stem Change
In the present tense, the 'e' in the middle of 'comenzar' changes to 'ie' (comienzo, comienzas) except for the 'we' (nosotros) and 'you all' (vosotros) forms, which remain comenzamos.
Starting an Action
When you use 'comenzar' to say you are starting another action, you must connect the two verbs using the little word 'a': 'Comenzar a + verb' (e.g., Comienzo a correr).
Forgetting the 'A' Connector
Mistake: “Comienzo estudiar ahora.”
Correction: Comienzo **a** estudiar ahora. (Always use 'a' before the next verb.)
Past Tense Spelling Trick
Mistake: “Yo comenzé (pronounced 'ko-men-SEH').”
Correction: Yo com**e**ncé. (The 'z' changes to a 'c' in the 'yo' form of the past tense to keep the sound correct.)
empezar
/em-peh-SAR//em.peˈsaɾ/

Examples
La película empieza a las ocho.
The movie starts at eight.
La clase empieza a las nueve.
The class starts at nine.
¿A qué hora empieza la película?
What time does the movie start?
Empecé un nuevo trabajo la semana pasada.
I started a new job last week.
The 'e' to 'ie' Change
In the present tense, the 'e' in 'empezar' changes to 'ie' for most forms (yo, tú, él, ellos). Notice how 'nosotros' and 'vosotros' keep the original 'e'. Think of it as a 'boot verb' because the forms that change make a boot shape in the conjugation chart!
The 'z' to 'c' Spelling Rule
To keep the right sound, the letter 'z' changes to 'c' before an 'e'. You'll see this in the 'yo' form of the preterite past tense ('empecé') and all forms of the present subjunctive ('empiece', 'empieces', etc.).
Forgetting the Stem Change
Mistake: “Yo *empezo* la tarea.”
Correction: Yo *empiezo* la tarea. Don't forget that the 'e' changes to 'ie' in the present tense for most forms.
iniciar
ee-nee-SYAR/i.niˈsjar/

Examples
Vamos a iniciar la discusión después del café.
We are going to start the discussion after coffee.
Necesitamos iniciar la reunión a las diez en punto.
We need to start the meeting exactly at ten o'clock.
El presidente inició una nueva investigación sobre el caso.
The president began a new investigation into the case.
Transitive Use
When you use 'iniciar' in this way, it always needs to 'start' something directly. For example, 'iniciar el coche' (start the car).
Confusing Start/Begin
Mistake: “La clase inicia a las tres.”
Correction: La clase empieza a las tres. ('Empezar' or 'comenzar' are usually better when the subject starts by itself, like a class or a movie.)
arrancar
/ah-rrahn-KAHR//araŋˈkar/

Examples
Mi coche viejo tarda en arrancar con el frío.
My old car takes a while to start in the cold.
El coche no quiere arrancar en las mañanas frías.
The car doesn't want to start on cold mornings.
Espera un momento, el ordenador está arrancando.
Wait a moment, the computer is booting up.
Spelling Change Alert
In the 'I' form of the past tense (Preterite), the 'c' changes to 'qu' (arranqué). This ensures the word still has a hard 'k' sound.
Avoid 'arrancé'
Mistake: “Escribí 'arrancé' ayer.”
Correction: Escribí 'arranqué' ayer. We use 'qu' to keep the hard 'c' sound before the letter 'e'.
abrir
ah-BREER/aˈβɾiɾ/

Examples
El restaurante abre a mediodía.
The restaurant starts/opens at noon.
Van a abrir una nueva tienda de café en mi barrio.
They are going to open a new coffee shop in my neighborhood.

/en-TRAR//enˈtɾaɾ/

Examples

She starts her new job next week.

Starting an Action
To mean 'to start doing something,' you must follow 'ponernos' with the preposition 'a' and then the action verb (infinitive): ponernos a + [action].
Missing the 'a'
Mistake: “Vamos a ponernos estudiar.”
Correction: Vamos a ponernos A estudiar. (The 'a' is required to link 'ponerse' to the following action.)
ponerme
/po-NER-me//poˈneɾme/

Examples

I have to start reading this book.
Tengo que ponerme a estudiar para el examen final.

The Essential 'A'
When 'ponerme' means 'to start doing something,' you MUST follow it with the small word 'a' and then the activity's verb (infinitive): 'ponerme a + infinitive'.
Forgetting the Preposition
Mistake: “Voy a ponerme leer el libro.”
Correction: Voy a ponerme a leer el libro. (The 'a' is required for the meaning 'to start.')
