Ser vs. estar: the core distinction
Goal: Choose between ser and estar in everyday sentences — including the same adjective with each verb, and where things and events are.
The rule of thumb
Ser says what someone or something is — identity and lasting characteristics. Estar says what condition someone or something is in right now.
A useful test: could this change in an hour? If so, it’s almost certainly estar.
Use ser for…
| Use | Example |
|---|---|
| name, job, nationality, origin | Sou engenheiro. /ˈso(w) ẽ.ʒẽˈɲe(j).ɾu/ I’m an engineer. |
| personality, lasting traits | Ela é alegre. /ˈɛ.lɐ ˈɛ aˈlɛ.ɡɾi/ She’s a cheerful person. |
| marital status | Sou casado. /ˈso(w) kaˈza.du/ I’m married. |
| when and where an event happens | A festa é amanhã. /a ˈfɛs.tɐ ˈɛ a.mɐ̃ˈɲɐ̃/ The party is tomorrow. |
Use estar for…
| Use | Example |
|---|---|
| feelings and moods right now | Tô feliz. /ˈto feˈlis/ I’m happy. |
| temporary states | Tô cansado. /ˈto kɐ̃ˈsa.du/ I’m tired. |
| how something looks or seems right now | Você tá bonita hoje. /voˈse ˈta buˈni.tɐ ˈo.ʒi/ You look nice today. |
| where a person or object is | Meu celular tá na mesa. /ˈmew se.luˈlaʁ ˈta na ˈme.zɐ/ My phone is on the table. |
Same adjective, different meaning
Many adjectives work with both verbs, and the verb changes the message:
| ser | estar |
|---|---|
| Ela é bonita. /ˈɛ.lɐ ˈɛ buˈni.tɐ/ She’s beautiful (that’s how she is). |
Ela tá bonita hoje. /ˈɛ.lɐ ˈta buˈni.tɐ ˈo.ʒi/ She looks lovely today. |
| Ela é alegre. /ˈɛ.lɐ ˈɛ aˈlɛ.ɡɾi/ She has a cheerful personality. |
Ela tá alegre. /ˈɛ.lɐ ˈta aˈlɛ.ɡɾi/ She’s in a good mood (right now). |
This is also why Eu sou cansado /ˈew ˈso(w) kɐ̃ˈsa.du/ is wrong for “I’m tired”: with ser, it describes a permanent trait — something like “I’m a tiring person.” Right now, you’re tired with estar: Tô cansado /ˈto kɐ̃ˈsa.du/.
Where is it? Estar, ser, or ficar
People and things that move → estar
- Onde você tá? /ˈõ.d͡ʒi voˈse ˈta/ — Where are you?
- Meu celular tá na mesa. /ˈmew se.luˈlaʁ ˈta na ˈme.zɐ/ — My phone is on the table.
Events (parties, meetings, games) → ser, for both time and place
- A festa é amanhã. /a ˈfɛs.tɐ ˈɛ a.mɐ̃ˈɲɐ̃/ — The party is tomorrow.
- A festa é na casa do João. /a ˈfɛs.tɐ ˈɛ na ˈka.zɐ du ʒoˈɐ̃w̃/ — The party is at João’s place.
Places that never move (buildings, cities, the bathroom) → usually ficar /fiˈka(ʁ)/
- Onde fica o banheiro? /ˈõ.d͡ʒi ˈfi.kɐ u bɐ̃ˈɲe(j).ɾu/ — Where’s the bathroom?
Ser is also possible for fixed places, but estar is not. You’ll meet ficar properly in lesson 14-02.
In conversation
- Nossa, você tá bonita hoje!/ˈnɔ.sɐ voˈse ˈta buˈni.tɐ ˈo.ʒi/Wow, you look great today!
- Hoje tô muito feliz./ˈo.ʒi ˈto ˈmũj̃.tu feˈlis/I'm really happy today.
- — Você é casado? — Sou, sim./voˈse ˈɛ kaˈza.du/ — /ˈso(w) ˈsĩ/"Are you married?" "Yes, I am."
- A festa é amanhã./a ˈfɛs.tɐ ˈɛ a.mɐ̃ˈɲɐ̃/The party is tomorrow.
- A festa é na casa do João./a ˈfɛs.tɐ ˈɛ na ˈka.zɐ du ʒoˈɐ̃w̃/The party is at João's place.
- Meu celular tá na mesa./ˈmew se.luˈlaʁ ˈta na ˈme.zɐ/My phone is on the table.
- Com licença, onde fica o banheiro?/kõ liˈsẽ.sɐ ˈõ.d͡ʒi ˈfi.kɐ u bɐ̃ˈɲe(j).ɾu/Excuse me, where's the bathroom?
- O café tá frio./u kaˈfɛ ˈta ˈfɾi.u/The coffee's (gone) cold.
Watch out
“Permanent vs. temporary” is only a rule of thumb. Events use ser even though they’re one-off — A festa é amanhã /a ˈfɛs.tɐ ˈɛ a.mɐ̃ˈɲɐ̃/ (“The party is tomorrow”) — and fixed places use ficar, not estar. Learn the location rules above as their own pattern.
Weather right now takes estar. Tá frio hoje. /ˈta ˈfɾi.u ˈo.ʒi/ — “It’s cold today.”
Don’t use estar for buildings.
✗ O restaurante tá na esquina.
✓ O restaurante fica na esquina. /u ʁes.tawˈɾɐ̃.t͡ʃi ˈfi.kɐ na isˈkĩ.nɐ/ — “The restaurant is on the corner.”
Quick check
1. "I'm tired." — Sou cansado or Tô cansado?
Tô cansado. /ˈto kɐ̃ˈsa.du/ (written: Estou cansado. /isˈto(w) kɐ̃ˈsa.du/) Sou cansado would describe a permanent trait.
2. What's the difference between Ela é bonita and Ela tá bonita?
Ela é bonita. /ˈɛ.lɐ ˈɛ buˈni.tɐ/ — She’s a beautiful person.
Ela tá bonita. /ˈɛ.lɐ ˈta buˈni.tɐ/ — She looks nice right now / today.
3. Fill in: A reunião ___ às três. ("The meeting is at three.")
é — events take ser.
A reunião é às três. /a ʁe.u.niˈɐ̃w̃ ˈɛ as ˈtɾe(j)s/
4. Fill in: As chaves ___ no carro. ("The keys are in the car.")
tão / estão — movable objects take estar.
As chaves tão no carro. /as ˈʃa.vis ˈtɐ̃w̃ nu ˈka.ʁu/
