Here's a breakdown of why:
* Grammatically: "Your" is a possessive pronoun, indicating something belongs to the person you're talking to. "Eyes" is a plural noun referring to the organs of sight.
* Usage: We use "your eyes" frequently in everyday language to:
* Draw attention to someone's eyes: "Your eyes are beautiful."
* Refer to their perspective: "What do you see through your eyes?"
* Direct someone's attention: "Look at that with your eyes."
So, while it doesn't have a singular origin story, its use is deeply rooted in our understanding of language and how we communicate.
