Both words are possessive pronouns, meaning they indicate ownership or belonging. They are derived from the word "tum" which means "you." However, they differ in their gender and number:
* Tere: This is the masculine singular form, used when referring to a single male "you."
* Teri: This is the feminine singular form, used when referring to a single female "you."
Here are some examples:
* Tere ghar kaha hai? (Where is your house?) - You are talking to a male person.
* Teri kitaab kaha hai? (Where is your book?) - You are talking to a female person.
