What is the difference between Ser and Estar?
Both ser and estar mean "to be" in English — but they are used in completely different situations. This is one of the first major hurdles for English speakers learning Spanish.
When to use SER
Use ser for permanent or inherent characteristics:
- Identity: Soy australiano. (I am Australian.)
- Profession: Ella es profesora. (She is a teacher.)
- Origin: Somos de Sydney. (We are from Sydney.)
- Time/dates: Son las tres. (It is three o'clock.)
- Relationships: Es mi hermano. (He is my brother.)
When to use ESTAR
Use estar for temporary states, locations, and conditions:
- Location: Estoy en Melbourne. (I am in Melbourne.)
- Feelings: Estoy cansado. (I am tired.)
- Health: Está enferma. (She is sick.)
- Ongoing actions: Estamos comiendo. (We are eating.)
Quick Memory Trick
Think of it this way: SER = DOCTOR (Description, Origin, Characteristic, Time, Occupation, Relationship) and ESTAR = PLACE (Position, Location, Action, Condition, Emotion).
