The word ‘back’ in Spanish is translated as ‘espalda’ when referring to the body part or a physical location behind something. However, if you are looking to use ‘back’ in a different context, such as returning to a place, the term you would use is ‘volver’.
For example, if you want to say ‘I am going back home,’ you would say ‘Voy de regreso a casa.’ In this case, ‘de regreso’ means ‘back’ in the sense of returning.
In conversations, it’s important to understand the context to choose the correct translation. If you’re talking about someone’s back, ‘espalda’ is the appropriate term. But if you are referring to the action of going back, consider using ‘volver’ for clarity.
