Possessive Pronouns in Tagalog grammar are words used to indicate possession or ownership of one thing or person by another. They are used to replace a noun that has already been mentioned or understood, and maintain a relationship between the thing or person that owns and the thing or person that is owned. In Tagalog, possessive pronouns have two categories: singular and plural. Some common examples of Tagalog possessive pronouns are “ko” (my), “mo” (your), and “nya” (his/her).
