One of the hardest parts of learning a romance language—especially one like Spanish—is verb conjugation.
In Spanish, the way a verb is conjugated depends on a number of factors, including the subject, the verb tense, and the purpose of the sentence itself. That means that there are actually many versions of each verb, all of which mean something slightly different. And because so much of understanding Spanish revolves around verbs, it’s an important (though pretty confusing) part of learning Spanish as a second language.
If you’re taking the AP Spanish exam, ser is one of the most critical verbs that you need to know—and know how to conjugate. Unfortunately, the conjugations for ser can be pretty tricky. But we’re here to help. In this article, we’ll give you every possible verb conjugation for the Spanish verb ser, which means “to be.” We’ll even give you a quick rundown on what ser means and when to use it!
So… ¡si estan listos, vamos!
It's time to do like Dora and "Come on, vamanos!"

Meaning and Usage of Ser
As we mentioned earlier, ser means “to be” in Spanish. But if you’re studying Spanish, you know that there’s a second verb that means “to be” as well: estar. (We’ll talk about estar in another article, so you don’t need to worry about it now.)
Additionally, ser is an irregular verb. That means it doesn’t follow the normal patterns of conjugations that a regular verb—ike hablar (to speak) or vivir (to live)—do. Unfortunately, there’s no easy tip, trick, or formula to help you nail the ser conjugation each and every time. The only way to make sure you know the ser conjugations is to memorize them.
So how do you know when to use ser?
In general, ser is used to talk about what something is. You can think of ser as a way to talk about a thing’s permanent state or a set of characteristics that don’t change. To show you how this works, here are examples of situations that require you to use ser:
Time and Date
If you’re talking about a specific time (on a clock) or calendar date, you should use ser.
Today is Tuesday.
It’s two o’clock.
Place of Origin and Nationality
Whenever you’re talking about someone’s home country, state, or where they were born, use a ser conjugation.
Claudio is Puerto Rican.
He is from Germany.
Occupation or Profession
Use the appropriate version of ser when speaking about a person’s job, profession, or occupation.
My grandmother was a doctor in Chile.
Adela is an architect.
Religious or Political Affiliation
Use ser when you’re talking about someone’s religion or the political party they belong to.
The president of the United States is Republican.
Martin is a Christian, so he wants to go to a Christian college.
What Something Is Made Of
When describing what something is made of, use ser. If you’re discussing how something is made, you’ll need to use a verb like hacer (to make) instead.
The bicycle is made of metal.
The tickets are made of paper.
Possession
When you’re talking about what something belongs to, use ser. This is how you indicate ownership!
Mitzi is Miguel’s dog.
Those books belonged to Mr. Villareal.
Permanent Relationships of One Person to Another
Use ser to indicate how people are related to one another.
She is Laura’s friend
Mrs. Mariz is Juan’s mother.
Where an Event Is Taking Place
Use a ser conjugation to talk about the time and location of a specific event.
The conference is at seven p.m.
The last World Cup was in Russia.
Essential Characteristics of People and Things
When deciding between ser and estar to talk about characteristics, use ser when you’re talking about permanent, unchanging, and/or essential traits of a person or item.
Colombia is a big country.
José and Clara are friendly.
Generalizations
If you’re talking in large generalities, use a ser conjugation.
The test was very difficult.
It’s fabulous to travel!
