Use ser for what something is: identity, origin, profession and characteristics: soy de Texas, es maestra. Use estar for how something is right now and where it is: estoy cansado, está en casa. The old “permanent vs temporary” rule breaks often; “what it is vs how it is” works better.

To be or not to be? That’s the question! And Spanish does it in style with not one, but two verbs meaning “to be.” Let’s talk about ser and estar, a troublesome pairing for beginners and advanced students alike.
Do you know how to use ser and estar in Spanish? If you’ve been learning Spanish for some time, you’ve definitely come across these two verbs. Before we go in-depth, here’s a quick way of differentiating between them: ser tells you what something is, while estar tells you what something does (or how something is). Check out the 5-minute video and examples below:
To be or not to be… in Spanish
You’ll often use soy (the first-person present of ser) to talk about what or who you are, and estoy (the first-person present of estar) to talk about what you are being or doing. For example:
- Soy aburrida/o (I am boring) vs. Estoy aburrida/o (I am bored)
- Soy cansada/o (I am a tired person) vs. Estoy cansada/o (I am tired now)
- Soy feliz (I am a happy person) vs. Estoy feliz (I am happy now)
- Soy callada/o (I am a quiet/silent person) vs. Estoy callada/o (I am being quiet)
- No soy lista/o (I am not clever) vs. No estoy lista/o (I am not ready)
- Soy guapa/o (I am good-looking) vs. Estoy guapa/o (I look good)
Big difference, no? 👀
Ser and estar in Spanish
A better way to think about it: ser is what something is, while estar is how or where it is right now. Identity versus state. Save these rules for whenever you’re in doubt about ser or estar in Spanish:
We use ser for:
- Date – Hoy es el 3 de septiembre (Today is September 3rd)
- Occupation – Soy profesora de español (I’m a Spanish teacher)
- Characteristics (physical characteristics, qualities, and personality traits) – Ella es muy bonita (She is very pretty)
- Time – Son las seis y media de la mañana (It is 6:30 am)
- Origin (place of origin) – Soy de México (I am from Mexico)
- Relationships – Ellas son mis tías (They are my aunts)
We use estar for:
- Position – Tus lentes están en la mesa (Your glasses are on the table)
- Location (geographic and physical location) – Estoy en casa (I am at home)
- Action (to describe what someone is doing or what is happening) – Estamos comiendo pizza (We’re eating pizza)
- Condition (or state of something/someone) – ¿Están enfermas? (Are you all sick?)
- Emotions (and feelings) – Ella está triste hoy (She is sad today)
Key takeaways
- Ser is typically used to describe the nature or identity of someone or something, the WHAT. We also use the verb for time and events.
- Estar is typically used to refer to a state of being that isn’t necessarily intrinsic, the HOW. We also use the verb to talk about the location of someone or something.
Why permanent versus temporary breaks
Here is the proof in one sentence: está muerto, he is dead. Nothing is more permanent than being dead, and Spanish uses estar. The permanent versus temporary shortcut cannot explain its most famous example. It gets you through some sentences and leaves you guessing on others.
The rule that works: what it is versus how it is
Ser is what something is: identity. Estar is how something is right now, or where it is: state and location.
- Soy Hannah. My identity. Ser.
- Estoy cansada. How I am today. Estar.
- Soy profesora. What I am. Ser.
- Estoy en Monterrey. Where I am. Estar.
- Soy de Estados Unidos. Origin is identity. Ser.
Run está muerto through it: death is a state you are in, not an identity you have. So estar. The identity question gets it right where the permanence question gets it wrong.
Words that change meaning with the verb
Some adjectives mean something different depending on which verb you pick.
- Es aburrido: he is boring. Está aburrido: he is bored.
- Es lista: she is smart. Está lista: she is ready.
- Es bueno: he is a good person. Está bueno: a comment on how someone looks.
Get aburrido backward at a party and you have called yourself a boring person when you meant the party was slow.
Will people understand you if you mix them up?
Yes, almost always. Soy cansada sounds odd, but nobody gets lost. Getting this right is polish, not survival, so do not let it stop you from talking. It is worth the effort because ser and estar show up in nearly every sentence you say.
Frequently asked questions
Not reliably. Está muerto uses estar, and nothing is more permanent than that. The rule that holds up: ser for identity, estar for state and location.
Location takes estar. Where something is counts as how it is right now, not what it is.
Origin is part of identity, so it takes ser.
Es bueno is about someone’s character: he is a good person. Está bueno comments on how someone looks.

Somebody taught you that ser is for permanent things and estar is for temporary things. That person meant well, and that rule is why you cannot use ser and estar. Here’s the proof in one sentence. Está muerto. He’s dead. I cannot think of anything more permanent than being dead. And Spanish uses estar. This permanent temporary rule cannot survive contact with that most famous example.
So, let me give you the version of the rule that actually works, one that finally made it click for me after I moved to Mexico. Ser is what something is. Estar is how something is doing or where it is. Identity versus state. What it is versus how it is right now. Soy Hannah. That’s my identity. Ser.
Estoy cansada. That’s my state today. Estar. Soy profesora. What I am. Estoy en Monterrey. Where I am. Identity ser.
Location and condition. Estar. And here’s why this beats the old rule. Está muerto. Permanent? Completely. But death is a state you are in, not an identity you have. So, estar.
Now the fun part, because this is where Spanish gets genuinely expressive. Some words change meaning depending on which verb you pick and Mexicans play with this constantly. Ser aburrido means to be boring as a person. Estar aburrido means to be bored right now. Getting those backward at a party and you’ve just called yourself a boring human being instead of saying that the party is slow. My students have done this in front of the host. Ser listo. Ser listo.
To be clever. Estar listo. To be ready. Es lista. Means she’s smart. Está lista. Means she’s ready to go. One verb choice.
Totally different compliment. And the one everyone eventually steps on. Ser bueno versus estar bueno. Es bueno. He’s a good person. Está bueno. Is a comment on how someone looks. If you’ve ever meant to call someone kind and accidentally called them hot, you’ve discovered this verb pair the traditional way.
Tell me in the comments or wherever you’re listening which of these pairs got you. Mine was aburrida. Quick pause on the grammar patrol. Will Mexicans understand you if you mix them up? Yes. Almost always. Soy cansada instead of estoy cansada sounds odd, but nobody’s lost. This is just a polish, not survival, so don’t let it stop you from speaking.
But it is the high value polish because ser and estar show up in practically every sentence you will ever say. So here’s your drill out loud wherever you are. I say the English, now you pick the verb before I do. I’m a teacher. Identity. Soy profesora. Say yours. Soy and your job.
I’m tired. Estar. Estoy cansada. I’m at home. Location. Estoy en casa. I’m from the United States. Origin is identity.
Soy de Estados Unidos. The coffee is hot. Condition right now. El café está caliente. If you caught yourself pausing on any of those, good. The pause is the question working. What is it or how it is? The pause gets shorter every time you speak.
This is the actual path to fluency with this pair. Use, not memorization. Charts do not build reflexes. Speaking builds reflexes. That is precisely what we do in coaching at Speak Better Spanish. The ser versus estar is one of the first reflexes we train because it pays off in every single sentence. If you want a plan for your own Spanish, where you are, what to train next, I offer a free Spanish roadmap session. No pressure and you leave with a plan either way.
