Questions & Answers about El piso es liso.

What does piso mean in this sentence?

Piso here means floor (the bottom surface of a room). In most of Latin America piso refers to the floor itself. (In Spain piso can also mean apartment, so be careful with context.)

Why do we use es (from ser) and not está (from estar)?

We use ser to describe inherent or permanent characteristics. Saying El piso es liso tells us that the smoothness is an essential quality of that floor. Using estar would suggest a temporary state, which doesn’t fit well for a floor’s texture.

What exactly does liso mean? Could it be translated as “flat” or “smooth”?

Liso means smooth, emphasizing a surface free of bumps or texture. You can translate El piso es liso as “The floor is smooth.” While flat sometimes works, it usually refers to something being level or horizontal, not necessarily bump-free.

How do I make the sentence plural or feminine?
