Other forms: possessives
Being possessive means you're being a little selfish about people or things in your life: you're clinging to them tightly and saying "Mine!"
Being possessive isn’t a good thing — possessive people are usually insecure and controlling. For example, you're being possessive of your pooch if you won't let anyone else play with it. A friend might be possessive of you if they get jealous when you hang out with other people. But in grammar, possessive is less creepy: a possessive word indicates ownership, like the word “dog's” in the sentence "Your dog's bowl just spilled on the carpet."
