- Identify the correct conjugations of the verb ser (to be)
- Recognize possession indicated by ser + de
El verbo ser
The verb ser means “to be”. Just as “to be” has an irregular conjugation in English (I am, you are, he/she is…), the verb ser is very irregular in Spanish. Therefore, it is important that you memorize it! When you change the verb depending on the subject, like the example below, you are conjugating the verb. In Spanish to conjugate verbs, you will give them a different form for each of the six subject pronouns.
Examples of conjugating with singular subjects:
Examples of conjugating with plural subjects:
- nosotros somos (We are)
- vosotros sois* (You are)
- ellos son / ellas son / ustedes son (They are / They (feminine) are / You (plural) are)
|ser (to be)|
|yo soy||nosotros somos|
|tú eres||vosotros sois*|
|él es / ella es / usted es||ellos son / ellas son / ustedes son|
* Remember that the “vosotros” form is only used in Spain. The Latin American equivalent is ustedes son.
Up to this point, you have seen ser used in the following ways:
- to identify someone/something
- to ask or say where someone is from (origin)
- To ask and say your profession
- To ask and answer about dates.
- ¿Cuándo es tu cumpleaños?
- Es el primero de marzo.
Possession with ser
Ser is also used to ascribe ownership, in combination with the preposition de (of). Be careful! English uses an apostrophe to say who something belongs to, but in Spanish we have to use a phrase with “de”.
