Your is used before a noun to show that something belongs to the person or people being spoken to. It can be used with one person or many people.
“Your” comes from Old English “ēower,” the possessive form of the plural “ye.” Over time, English simplified the system, and “your” became the standard possessive for both singular and plural “you.”
“Your” is like a grammatical arrow pointing from an object back to the listener. The fact that it works for both one and many people is another sign of how English quietly lost number differences in its pronouns.
