Ser vs Estar

Two verbs for 'to be' — and why Spanish needs both.

English uses one verb for 'to be': 'I am tall', 'I am at home'. Spanish splits this into two: ser and estar. Ser is essence (who and what you are). Estar is state (where you are and how you are right now). The difference is the heart of beginner Spanish.

Ser — conjugation

yo soy = I am. tú eres = you are. él/ella/usted es = he/she/you are. nosotros somos = we are. vosotros sois = you all are. ellos/ellas/ustedes son = they/you all are. Memorize like a chant: soy, eres, es, somos, sois, son.

Estar — conjugation

yo estoy = I am. tú estás = you are. él/ella/usted está = he/she/you are. nosotros estamos. vosotros estáis. ellos/ellas/ustedes están. Watch the accents: estás, está, están — all stress the last syllable.

Use ser for…

Name: Soy Ana — I'm Ana. Profession: Es médico — he's a doctor. Nationality: Somos rusos — we're Russian. Origin: Soy de Moscú — I'm from Moscow. Permanent qualities: Es alta — she's tall. Time and date: Son las tres — it's three o'clock.

Use estar for…

Location: Estoy en casa — I'm at home. Wellbeing: Estás bien — you're fine. Temporary states: La sopa está caliente — the soup is hot (right now). Mood: Estoy contento — I'm happy (right now).

Same word, different verb

Es aburrido = he's boring (as a person). Está aburrido = he's bored (right now). Es bueno = he's a good person. Está bueno = it tastes good / he's healthy now. This whole distinction is a Spanish-language philosophy in itself.
