Learn Hardcore Spanish (Spain): El suelo de la sala está muy limpio.

In Spanish we generally use the definite article where English often drops it. Suelo is a masculine, singular noun (“floor”), so we say el suelo (“the floor”) rather than just suelo.

What’s the difference between suelo and piso?

Both can translate as “floor,” but in Spain:

Suelo refers specifically to the surface you walk on.
Piso more often means an apartment or a level of a building (“third floor”).
If you want “the floor of the room,” suelo is the most natural choice.

Why de la sala instead of en la sala?

De la sala literally means “of the living room,” indicating possession: “the living-room’s floor.”
En la sala would mean “in the living room,” describing location.
You could say El suelo en la sala está muy limpio, but native speakers typically talk about “the floor of X” with de.

Could I omit de la sala and just say El suelo está muy limpio?

Yes. If the context makes clear which floor you’re referring to, dropping de la sala is perfectly fine.

Why do we use está instead of ?
