The word "su" in Spanish possesive determiners
The word "su" has a lot of meaning such as: his, her, your (formal), their. How can I discriminate them? Please help me with this! Gracias!
Context. Think of this: "The word "mine" has a lot of meanigs such as: mía, mío, mías, míos. How can I discriminate them?"
In "Vi a Pedro y a Juan saliendo de su casa" is impossible to determine the owner. Pedro? Pedro and Juan? Juan? Another person??? You need the rest of the story.
