Stem-changing verbs (e to ie)

The "e to ie" Change

In Spanish, some verbs have a little twist when you conjugate them in the present tense: the vowel e in the stem changes to ie.

For example, take the verb empezar (to start). Instead of saying "yo empezo", you change the e to an ie:

I start the new project today.
Yo empiezo el nuevo proyecto hoy.

This vowel change happens for almost all subjects (I, you, he, she, they), but it skips nosotros (we).

SubjectEmpezar (to start)
yoempiezo
empiezas
él, ella, ustedempieza
nosotrosempezamos
ellos, ellas, ustedesempiezan
Does he start the business with you?
¿Él empieza el negocio contigo?

More Stem-Changing Verbs

Several other common verbs follow this exact same pattern, such as comenzar (to begin), preferir (to prefer), and entender (to understand).

They begin the new business.
Ellas comienzan el nuevo negocio.
I prefer the new idea.
Yo prefiero la idea nueva.
The intelligent student understands the plan.
El estudiante inteligente entiende el plan.

Planning Projects

The verb pensar means "to think," but it is also used to talk about your plans and intentions. Just use a conjugated form of pensar followed by a second verb in its original, unconjugated form.

I plan to start the business.
Yo pienso empezar el negocio.
He plans to start an excellent project.
Él piensa empezar un proyecto excelente.
