Spanish Ser vs. Estar: two verbs for "to be", and when to use which

Five lessons on the most-used verbs in the language, followed by graded conversation where you make the ser/estar choice dozens of times per session.

Spanish has two verbs where English has one. Ser is for what something is: identity, origin, profession, personality, what it is made of, what time it is (soy australiano, es médica, son las tres). Estar is for how or where something is right now: location, feelings, temporary conditions, actions in progress and the result of a change (estoy cansado, está en la cocina, estamos comiendo). Most textbooks hand you a mnemonic — DOCTOR for ser, PLACE for estar — and the mnemonics are genuinely useful. They just do not survive contact with a live conversation on their own.

The difficulty is that English speakers have never had to make this decision, so nothing in the mental grammar flags it. Location feels permanent, yet it takes estar (Australia está lejos). A handful of adjectives change meaning with the verb — es aburrido is boring, está aburrido is bored; es listo is clever, está listo is ready — so the wrong verb does not just sound off, it says something else. And hay sits beside both verbs for saying that something exists at all, which is a third choice learners rarely get taught explicitly.

These five lessons walk through ser, estar, the tricky pairs, the progressive (estar + -ando/-iendo) and hay vs. está. The practice that makes it stick happens in the AI tutor: every message you send is scored 0–100 with a correction, and because ser/estar shows up in almost every sentence, one twenty-minute session gives you more graded decisions than a week of worksheets. Recurring slips are tracked in your Error Bank — ser vs. estar (location) is one of the patterns Juntos detects automatically — and resurfaced in spaced-repetition reviews until you get them right without thinking.

What's in this course

  1. SER — the permanent one — Identity, origin, characteristics
  2. ESTAR — the temporary one — Location, feelings, conditions
  3. The tricky pairs — When the same word changes meaning
  4. Estar + -ando/-iendo — What's happening right now
  5. Hay vs. está — 'There is' vs. 'it is (somewhere)'

Each lesson below is the same material used inside the Juntos app, with two of its exercises to try. In the app every lesson has the full exercise set, and the AI tutor grades your conversation practice against what you have learned.

Lesson 1: SER — the permanent one

Identity, origin, characteristics

SER: what something fundamentally IS 🪪

Use ser for the essence — things that define what/who something is. Remember it with DOCTOR:

  • Descriptions — Ella es alta. (She is tall.)
  • Occupation — Soy ingeniero. (I'm an engineer.)
  • Characteristics — Es simpático. (He's nice.)
  • Time/date — Son las dos. (It's two o'clock.)
  • Origin — Soy de Australia. (I'm from Australia.)
  • Relationships — Es mi hermano. (He's my brother.)

Yo ___ de Australia.

I am from Australia.

Show answer

soy — Origin → ser. Soy de Australia.

Mi hermano ___ médico.

My brother is a doctor.

  1. está
  2. es
  3. estar
Show answer

es — Occupation → ser: es médico.

Lesson 2: ESTAR — the temporary one

Location, feelings, conditions

ESTAR: state & place 📍

Use estar for location, emotions, and temporary conditions — how something is right now. Remember PLACE:

  • Position/Location — Australia está lejos. (Australia is far.)
  • Action (progressive) — Estoy comiendo. (I'm eating.)
  • Condition — La comida está fría. (The food is cold.)
  • Emotion — Estoy cansado. (I'm tired.)

The golden rule for you: WHERE something is → always estar. ¿Dónde está el baño? México está en Norteamérica.

Try it

Australia ___ muy lejos de aquí.

Australia is very far from here.

  1. es
  2. está
  3. son
Show answer

está — Location/distance → estar: está muy lejos. This was your exact slip!

¿Dónde ___ (estar) el baño?

Where is the bathroom?

Show answer

está — Location → estar: está.

Lesson 3: The tricky pairs

When the same word changes meaning

Same adjective, different verb, different meaning 🔀

Sometimes both work — but the meaning flips:

  • Él es aburrido = He is boring (personality) vs. Él está aburrido = He is bored (right now).
  • La manzana es verde = The apple is green (its colour) vs. está verde = it's unripe.
  • Ser listo = to be clever vs. estar listo = to be ready.

Rule of thumb: ser = the essence, estar = the current state.

Try it

¡Vámonos! ¿___ listo? (= Are you ready?)

Let's go! Are you ready?

  1. eres
  2. estás
  3. es
Show answer

estás — 'Ready' (a current state) → estar: ¿Estás listo?

Mi abuela ___ muy inteligente. (a defining trait)

My grandma is very intelligent.

  1. está
  2. es
  3. están
Show answer

es — A permanent characteristic → ser: es inteligente.

Lesson 4: Estar + -ando/-iendo

What's happening right now

The progressive: caught in the act 🎬

estar + gerund = something in progress right now:

  • -ar → -ando: Estoy hablando. (I'm talking.)
  • -er/-ir → -iendo: Está comiendo. (He's eating.)

Irregular gerunds: leyendo (reading), durmiendo (sleeping), pidiendo (ordering), diciendo (saying).

A common slip: after cuando, use a normal verb, not the gerund — cuando compro comida, never "cuando comprando". The -ando form always needs estar with it.

Try it

¿Qué estás ___ (hacer)? — Estoy cocinando.

What are you doing? — I'm cooking.

Show answer

haciendo — hacer → haciendo.

No puedo hablar, ___ (comer).

I can't talk, I'm eating.

  1. como comiendo
  2. estoy comiendo
  3. soy comiendo
  4. comiendo
Show answer

estoy comiendo — In progress right now → estoy + comiendo. Never ser!

Lesson 5: Hay vs. está

'There is' vs. 'it is (somewhere)'

Existence vs. location 🗺️

  • hay = there is / there are (existence, new info): Hay un banco cerca.
  • está / están = a specific thing's location: El banco está en la esquina.
Rule of thumb: a / un / una / muchos → hay. el / la / mi / este → está.
¿Hay un cajero por aquí? — Sí, el cajero está al lado del súper.

Try it

¿___ una farmacia cerca de aquí?

Is there a pharmacy near here?

  1. Está
  2. Hay
  3. Es
Show answer

Hay — una farmacia (unspecific, existence) → hay.

¿Dónde ___ el baño?

Where is the bathroom?

  1. hay
  2. está
  3. es
Show answer

está — THE bathroom, specific location → está.
