To Be or Not to Be in Spanish: The Uses of Ser and Estar

Feeling particularly upset? Emotions are usually expressed with "estar."

“To be, or not to be–that is the question:

Whether ’tis nobler in the mind to suffer

The slings and arrows of outrageous fortune

Or to take arms against a sea of troubles

And by opposing end them…”

 Hamlet must have been thinking in Spanish when he pronounced his most famous soliloquy, for there seems to be nothing more confusing to Spanish learners than the use of ser and estar. These verbs are both the equivalent of the English “to be,” and will be the foundation to one too many of your conversations in Spanish.  If you really want to learn Spanish, you need to understand ser and estar. Particularly towards the beginning of your language journey, understanding the differences between ser and estar can be tricky, but let me make it simple. 

Conjugating ser and estar

Because they are both irregular, conjugating these verbs will require memorization. Estar, however, is only irregular for first person singular.


Yo soy

Tú eres

Él/ella/usted es

Nosotros/as somos

Vosotros/as sois

Ellos/ellas/ustedes son


Yo estoy

Tú estás

Él/ella/usted está

Nosotros/as estamos

Vosotros/as estáis

Ellos/ellas/ustedes están
