This & That – Japanese Pronouns (Yes Japanese)

これmeans “this.”それ means “that.” あれ means “that over there.” The word you are using to refer to an object will depend on where that object is located. If the object is near you but far away from your speaker, you should useこれ. If the object is far away from you but close to your listener, you should use それ. If the object is far away from both the speaker and listener, あれ is the best choice.
