Questions & Answers about El cuadro está arriba del sofá.
Spanish uses estar for location in most cases, so when you say where something is, you normally use está:
Use ser for identity, origin, profession, and other more permanent descriptions, but not for ordinary physical location.
A useful shortcut is:
- ser = what something is
- estar = where something is / how something is
So here, the sentence is about the picture’s position, which is why está is correct.
Cuadro can mean several related things depending on context, including:
- painting
- picture
- framed picture
- sometimes even frame
In this sentence, it most naturally means a picture or painting hanging above the sofa.
So cuadro is a slightly broader word than just one exact English word. The context tells you which English translation fits best.
