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!".

Pronunciation: /pə'zɛsɪv /
English Description: eager to acquire and possess things especially material possessions or ideas
Chinese Translation: 占有欲强的(zhan4 you3 yu4 qiang2 de)
Spanish Translation: posesivo
STORY: 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."

EXAMPLE SENTENCE:

Fans use it in the possessive to describe a particular character that they have romantic feelings toward.
Never mind that people have been possessive of their stuff and protective of their space forever.
