Questions & Answers about En el dormitorio de mi hermana hay una alfombra marrón muy suave.
In Spanish:
- hay = there is / there are (introduces the existence of something)
- es = is (describes what something is)
- está = is (describes location or temporary state of a specific thing)
In this sentence, you are introducing the existence of a carpet in the room, so you use hay:
If you were talking about a specific carpet already known, you might say:
- La alfombra está en el dormitorio de mi hermana.
The carpet is in my sister’s bedroom.
No. That word order sounds wrong in Spanish.
The normal patterns are:
- En el dormitorio de mi hermana hay una alfombra marrón muy suave.
- Hay una alfombra marrón muy suave en el dormitorio de mi hermana.
Both are correct. Spanish allows some flexibility, but hay usually comes before the thing that exists (the alfombra), not after it in this kind of sentence.
