This page: Learn the forms of the verb ser (to be) in Spanish.



Grammar Lesson

There are two forms of the verb "to be" in Spanish. One is ser, which we will learn in this lesson, and the other is estar, which we will learn in next week's lesson. We will also learn more about the differences in use between ser and estar in next week's lesson. The verb ser is an irregular verb. The forms are listed in the table below. A different form of the verb is used depending on the subject. Click on the forms of the verb in the table below to hear the pronunciation and repeat.

The verb ser (to be)
Subject pronouns Form of ser English translation
yo ► soy I am
► eres you are
usted, él, ella ► es you are/he is/she is
nosotros, nosotras ► somos we are
vosotros, vosotras ► sois you are (used in Spain only)
ustedes, ellos, ellas ► son you are/they are

Note: Remember that the subject pronoun doesn't necessarily have to be used in a sentence if it is clear who the subject is based on the context or verb form. For example, with the verb soy, it is obvious that the subject is yo so the subject is generally not used. The subject may still be used, however, for emphasis.



Section 1
Select the correct form of the verb for the subject.

1. Yo      

2. Nosotros      

3. Usted      

4. Tú      

5. Ellos      

6. Ustedes    

7. Vosotros      

8. Marco      
Since it's a man's name, treat it like "he" (él).

9. Susana      
Since it's a woman's name, treat it like "she" (ella).

10. Los estudiantes (The students)      
Since it's plural, treat it like "they" (ellos).



Section 2
Fill in the blank with the correct verb form. (inteligente = intelligent)

1. Él inteligente.    

2. Yo inteligente.    

3. Usted inteligente.    

4. David inteligente.    

5. Tú inteligente.    

6. Nosotros inteligentes.    

7. Él inteligente.    

8. Ellos inteligentes.    

9. Ustedes inteligentes.    

10. Vosotros inteligentes.    

11. Los niños (the children) inteligentes.    

12. Susana inteligente.    



Making verbs negative in Spanish is very easy. Just add the word "no" before the verb.

  • Examples:
  • No soy de México.
  • Ella no es de Perú.
  • Los niños no son de Colombia.

Section 3
Change the sentence to negative. Don't forget to use correct capitalization, accents and punctuation, or the computer will mark it as incorrect.

1. Eres de Argentina.

2. Somos de Colombia.

3. Marco es inteligente.

4. Ustedes son de Costa Rica.

5. Luis y yo somos estudiantes.


Question Formation

Forming questions is also easy in Spanish. Just change the word order by putting the verb first. If there is no subject (the verb is already first), all you need is to put question marks. In Spanish an upside-down question mark (¿) is used at the beginning of the question as well as a regular question mark (?) at the end. In some sentences the subject can go right after the verb or at the end of the sentence. If a verb has an object or adverb, however, the subject usually goes after the object or adverb.

  • Examples:
  • ¿Eres de México?
  • ¿Es ella la profesora? (Is she the teacher?)

Often Spanish-speakers don't even change the word order for a question. They use the normal sentence word order and just add question marks (to written text) and question intonation (to spoken questions). We also do this in English when we are confirming something ("Maria is from Mexico?").

  • Examples:
  • ¿María es de México?
  • ¿Los niños son de Perú?


Find the Mistake

Find the mistake in the sentence and re-write it correctly in the space. Don't forget to use correct capitalization, accents and punctuation, or the computer will mark it as incorrect.

  • Example:
  • Ella son inteligente. → Ella es inteligente.

1. Mike y yo son de Australia.

2. Eyos son de California.

3. Soi de Colombia.

4. Francisco es no de Argentina.

5. Eres de China?
Be careful with this one! The error is in the punctuation. What punctuation is required for questions in Spanish?



Write a few sentences with the forms of the verb ser.

  • Examples
  • Soy de Illinois. (I am from Illinois.)
  • Mi mamá es alta. (My mom is tall.)
