Ser Vs Estar: A Guide For Total Beginners [2025]

English has one verb, "to be." However, Spanish has two: ser and estar. Ser describes what something fundamentally is (a teacher, tall, Mexican), while estar describes how something is right now (happy, tired, in the kitchen). Get this wrong and you'll say things like "I am boring" when you meant "I'm bored."

The good news? There are clear patterns for when to use each verb. Master the DOCTOR and PLACE memory tricks, learn which adjectives completely change meaning depending on the verb, and you'll stop second-guessing yourself every time you need to say "to be" in Spanish.

What Are SER and ESTAR?

Both ser and estar translate to "to be" in English, but they express fundamentally different ideas in Spanish grammar. Ser tells you what something is: its identity, nature, or essential qualities. Estar tells you how something is like its current state, location, or condition.

So technically, ser is permanent or defining, and estar is temporary or changeable. Your nationality? Ser. Your location? Estar. Your profession? Ser. Your mood? Estar. The distinction matters because using the wrong verb can completely change your meaning.

In Spanish, verbs change their form depending on who's doing the action. This is called conjugation. In English, "to be" changes to "I am," "you are," "he is"—Spanish works the same way, but with more variations.

The base forms are ser and estar (both meaning "to be"), but you'll never use these forms in a sentence. Instead, you'll use their conjugated forms based on who you're talking about.

SER (to be)

• Yo soy (I am)
• Tú eres (You are - informal)
• Él/Ella/Usted es (He/She is, You are - formal)
• Nosotros/as somos (We are)
• Vosotros/as sois (You all are - Spain)
• Ellos/Ellas/Ustedes son (They are, You all are)

ESTAR (to be)

• Yo estoy (I am)
• Tú estás (You are - informal)
• Él/Ella/Usted está (He/She is, You are - formal)
• Nosotros/as estamos (We are)
• Vosotros/as estáis (You all are - Spain)
• Ellos/Ellas/Ustedes están (They are, You all are)

Both ser and estar are irregular verbs, meaning they don't follow a predictable pattern. You can't guess these forms—you have to memorize them. Practice these until they're automatic. Write them out, say them aloud, drill them daily. Everything else in this guide builds on knowing these forms cold.

Part 2: When to Use SER

Use the DOCTOR acronym to remember the six main uses of ser. Each letter represents a situation where ser is the correct choice.

D - Descriptions (Essential Qualities)

Use ser for physical descriptions and qualities that define what something is. These are characteristics that don't change day to day.

Examples:

• La casa es gris. (The house is gray.)
• El perro es grande. (The dog is big.)
• Mi hermana es alta. (My sister is tall.)
• El libro es interesante. (The book is interesting.)

O - Occupations

Use ser to state someone's profession or job.

Examples:

• Ella es veterinaria. (She is a veterinarian.)
• Nosotros somos profesores. (We are teachers.)
• Mi padre es arquitecto. (My father is an architect.)

Important: In Spanish, you don't use "un" or "una" (a/an) before occupations. Don't say "Ella es una veterinaria"—just say "Ella es veterinaria."

C - Characteristics (Personality & Inherent Traits)

Use ser for personality traits and qualities that are part of someone's nature.

Examples:

• Él es inteligente. (He is intelligent.)
• Mi hermano es gracioso. (My brother is funny.)
• Tú eres amable. (You are kind.)
• Somos honestos. (We are honest.)

T - Time

Use ser for telling time, stating dates, and identifying days of the week.

Examples:

• Son las tres de la tarde. (It's three in the afternoon.)
• Es la una. (It's one o'clock.)
• Hoy es lunes. (Today is Monday.)
• Es el quince de abril. (It's April 15th.)
• Mañana es mi cumpleaños. (Tomorrow is my birthday.)

O - Origin

Use ser to say where someone or something is from.

Examples:

• Ella es de Rumanía. (She is from Romania.)
• Yo soy mexicano. (I am Mexican.)
• Somos de España. (We are from Spain.)
• Este vino es de Chile. (This wine is from Chile.)

R - Relationships

Use ser for family relationships and to show possession or belonging.

Examples:

• Él es mi tío. (He is my uncle.)
• Somos hermanos. (We are siblings.)
• Es mi libro. (It's my book.)
• Son mis amigos. (They are my friends.)

Special Case: Events and Parties

Even though we use estar for most locations, events and parties are different. Use ser to say where an event is taking place.

Examples:

• La fiesta es en mi casa. (The party is at my house.)
• El concierto es en el estadio. (The concert is at the stadium.)

When to Use ESTAR - The PLACE Method

Use the PLACE acronym to remember the five main uses of estar. Each letter represents a situation where estar is the correct choice.

P - Position/Posture

Use estar to describe physical positioning or posture.

Examples:

• Estoy sentado. (I am sitting.)
• Están de pie. (They are standing.)
• Estás acostado. (You are lying down.)

L - Location

Use estar for where someone or something is physically located. This is one of the most important rules: all physical locations use estar, even if the location seems permanent.

Examples:

• Estoy en Buenos Aires. (I'm in Buenos Aires.)
• Madrid está en España. (Madrid is in Spain.)
• La llave está en la mesa. (The key is on the table.)
• ¿Dónde estás? (Where are you?)
• Estamos en el parque. (We are in the park.)

Even though Madrid will always be in Spain, we still use estar because we're talking about location.

A - Action (Progressive Tenses)

Always use estar to form the present progressive—the equivalent of "-ing" verbs in English. This describes actions happening right now.

Formula: estar + gerund (verb ending in -ando/-iendo)

Examples:

• Estoy estudiando. (I am studying.)
• Ellos están comiendo pizza. (They are eating pizza.)
• ¿Qué estás haciendo? (What are you doing?)
• Estamos trabajando. (We are working.)
• Ella está corriendo. (She is running.)

C - Condition (Temporary States)

Use estar for states or conditions that can change. These are temporary situations, not permanent qualities.

Examples:

• La puerta está abierta. (The door is open.)
• Los platos están sucios. (The plates are dirty.)
• El café está caliente. (The coffee is hot.)
• La radio está rota. (The radio is broken.)
• Estoy enfermo. (I'm sick.)

In Spanish, death is considered a condition, not a permanent state, so you use estar.

• Ella está muerta. (She is dead.)
• Mi abuelo está vivo. (My grandfather is alive.)

E - Emotion (Feelings)

Use estar for emotions and feelings. These are how someone feels at a specific moment, not their general personality.

Examples:

• Estoy feliz. (I'm happy.)
• Ella está triste. (She's sad.)
• Estoy cansado. (I'm tired.)
• Están enojados. (They are angry.)
• ¿Cómo estás? (How are you?)
• Estoy muy contento. (I'm very happy/content.)

The difference matters:

• Soy feliz = I am a happy person (personality trait)
• Estoy feliz = I am happy right now (current feeling)
