Ser vs. estar

In Spanish, there are two verbs that mean "to be": ser and estar.

  • Use ser for characteristics and identity (what something is).
  • Use estar for temporary states, conditions, and locations (how someone feels or where something is).

Using ser or estar can even change the meaning of an adjective:

The book is boring.
El libro es aburrido.
The boy is bored.
El niño está aburrido.

Characteristics vs. States

Use ser for natural or permanent traits, and estar for conditions that can change or for locations.

The ice is cold.
El hielo es frío.
The ice is here.
El hielo está aquí.
The coffee is cold today.
El café está frío hoy.

The same applies to being clean (limpio) or dirty (sucio). A cat might be a clean animal by nature (ser), but a house is just clean right now (estar).

The cat is very clean.
El gato es muy limpio.
The house is clean now.
La casa está limpia ahora.

Adjective Agreement

As with ser, adjectives used with estar must match the gender and number of the noun they describe.

(Note: *Agua uses el in the singular for easier pronunciation, but it is a feminine noun. Its adjectives must be feminine!)*

The water is cold.
El agua está fría.
The cars are dirty.
Los coches están sucios.

Open and Closed

Always use estar for physical states like being open (abierto) or closed (cerrado).

The shop is open.
La tienda está abierta.
The museums are closed.
Los museos están cerrados.
