Ser vs. Estar (To Be)

Spanish has two verbs for "to be": ser and estar. They are completely different and cannot be used interchangeably.

Ser = permanent, identity, essence

Estar = location, condition, temporary state

This distinction is critical for Spanish learners.

  • Profession: Nosotros somos profesores. (We are teachers.)
  • Characteristics: El cielo es azul. (The sky is blue.)
  • Time & date: Son las tres. (It is 3 o'clock.)

  • How you feel: Estoy cansado. (I am tired.)
  • Current state: La puerta está abierta. (The door is open.)
  • Health/condition: ¿Cómo estás? (How are you?)

  • ser verde = to be green (color) vs. estar verde = to be unripe (condition)
