Ser and estar (AQA GCSE Spanish): Revision Notes
Ser and estar
Understanding the difference between ser and estar is crucial for Spanish learners, as both verbs mean "to be" in English but are used in completely different situations. Both verbs are irregular, which means their conjugations don't follow the standard patterns, so you'll need to memorise them carefully.
Because these verbs are completely irregular, there are no patterns to help you - you must memorise each form individually. This makes them challenging for beginners, but they're absolutely essential for speaking Spanish correctly.
The present tense of ser
The verb ser is used to describe permanent or inherent characteristics. Here are its present tense forms:
| English | Spanish |
|---|---|
| I am | soy |
| you are (informal) | eres |
| he/she/it is | es |
| we are | somos |
| you are (plural) | sois |
| they are | son |
When to use ser
Ser describes things that are generally permanent or unchanging about a person, object, or situation. This includes fundamental characteristics that define who or what something is.
Nationality and origin When talking about where someone is from, you always use ser because nationality is a permanent characteristic.
Example: Nationality
- Soy británico/a. (I'm British.)
- Es francesa. (She's French.)
- Somos mexicanos. (We're Mexican.)
Occupation and profession Someone's job or profession is expressed with ser, as it represents what they do as their main activity.
- Es profesor. (He's a teacher.)
Colour, size, and physical characteristics Permanent physical attributes that don't change regularly are described with ser.
- Es rojo. Es pequeño. (It's red. It's small.)
Personality traits Character traits and personality features that are consistent over time use ser.
- Son trabajadores. (They're hard-working.)
Telling the time Time expressions always use ser because time is a permanent, objective fact.
- Son las tres. (It's three o'clock.)
Certain adjectives always go with ser, including joven (young), viejo (old), barato (cheap), and caro (expensive). These never change to estar, regardless of context.
The present tense of estar
The verb estar focuses on temporary states, conditions, and locations. Here are its present tense forms:
| English | Spanish |
|---|---|
| I am | estoy |
| you are (informal) | estás |
| he/she/it is | está |
| we are | estamos |
| you are (plural) | estáis |
| they are | están |
When to use estar
Estar describes temporary situations, feelings, locations, and conditions that can change. It answers questions about how someone feels or where something is located.
Illness and health conditions When someone feels unwell or describes a temporary health state, estar is used.
- Estoy enfermo/a. (I'm unwell.)
Temporary appearance How someone looks at a particular moment, especially when it's different from usual, uses estar.
- Estás guapo/a. (You look handsome/beautiful.)
Feelings and emotions Emotional states that can change throughout the day are expressed with estar.
Example: Emotions
- Estoy contento/a porque gané un premio. (I'm happy because I won a prize.)
- Está triste hoy. (He's sad today.)
- Estamos nerviosos antes del examen. (We're nervous before the exam.)
Location and position Where someone or something is located always uses estar, regardless of whether it's temporary or permanent.
- Mi madre está en el jardín. (My mother is in the garden.)
Key distinction: Pay attention to phrases like ser listo (to be clever - a permanent trait) versus estar listo (to be ready - a temporary state). The same adjective can have completely different meanings depending on which verb you use!
