“Permanent or temporary” won’t always help. Look at the meaning: identity, location, condition, or the way a word changes with each verb.
Mistake 1: using estar for identity
Incorrect: Estoy estudiante.
Better: Soy estudiante.
A profession, nationality, origin, religion, or role normally classifies the person. Use ser: Soy india. Somos ingenieros. Ella es de Madrid.
Mistake 2: using ser for physical location
Incorrect: El banco es cerca de mi casa.
Better: El banco está cerca de mi casa.
Use estar to locate a person, object, or place. A city can exist for centuries and still takes estar: Madrid está en España. This is why permanence is a poor test.
Mistake 3: confusing hay with estar
Hay introduces something: Hay una farmacia en esta calle. Once both speakers know which pharmacy you mean, locate it with estar: La farmacia está al lado del banco.
Do not say hay la farmacia when you mean a known place. The article often gives the clue. Use hay una farmacia, then la farmacia está.
Mistake 4: translating age or possession with either verb
Spanish uses tener for age and possession. Say Tengo veinte años and Tengo un coche. Neither soy veinte años nor estoy veinte años works.
Mistake 5: treating every adjective as fixed
Some adjectives work with both verbs and change meaning.
- Es aburrido. He or it is boring.
- Está aburrido. He is bored.
- Es listo. She is clever.
- Está lista. She is ready.
- Es seguro. It is safe or certain.
- Está seguro. He is sure.
Learn the whole contrast, not an adjective beside one memorised verb.
Mistake 6: describing mood with ser
Use estar for a person's current mood or condition: Estoy cansada. Estamos contentos. ¿Estás bien? A defining personality trait can take ser: Es una persona alegre.
Mistake 7: forgetting agreement
The adjective still agrees with the person or thing. Say Ella está cansada, Ellos están cansados, and Las tiendas están abiertas. Choosing the right verb does not remove gender and number agreement.
Mistake 8: using ser with bien and mal
For condition, use estar bien or estar mal. Say El ejercicio está bien and Hoy estoy mal. To judge character or quality, choose a suitable adjective and meaning: Es una buena idea.
Mistake 9: building the present progressive with ser
Use estar plus the gerund for an action happening now: Estoy estudiando. Están comiendo. Do not say soy estudiando.
Spanish often uses the simple present where English uses a progressive form, so do not force this structure into every sentence. Trabajo en Delhi describes your normal work. Estoy trabajando focuses on what is happening now.
A better decision process
- Decide whether the sentence identifies something or locates and describes its condition.
- Check whether another verb such as tener or hay is actually needed.
- If an adjective works with both verbs, learn the two meanings through a pair of complete sentences.
- Check the verb form and adjective agreement after the meaning is clear.
Short practice
Choose ser, estar, tener, or hay. Conjugate the verb.

- En mi barrio ___ dos parques.
- Nosotros ___ cansados hoy.
- Yo ___ veintidós años.
- La clase ___ a las diez.
- Elena ___ muy lista, pero todavía no ___ lista para el examen.
- Ahora ellos ___ hablando con el profesor.
- La sopa ___ fría.
