Learn Spanish (Latin America): Este cuarto tiene una vista hermosísima. - This room has an extremely beautiful view.

To make an adjective mean "extremely" or "super," Spanish adds the suffix -ísimo. Since vista (view) is a feminine singular noun, the adjective hermosa (beautiful) drops its final -a and adds -ísima to match it, becoming hermosísima.

Is there a difference between una vista hermosísima and una vista muy hermosa?

They mean the exact same thing: "a very beautiful view" or "an extremely beautiful view." Using the -ísimo or -ísima ending is just a very common, expressive way native speakers intensify adjectives in everyday conversation instead of always relying on muy (very).

Why is it Este cuarto and not Esto cuarto?

Este is the masculine singular word for "this" when it comes right before a noun (like cuarto). Esto is the neuter version of "this"—you only use it when you aren't naming the specific object, like when pointing and asking "¿Qué es esto?" (What is this?).

Can I use habitación instead of cuarto for "room"?
