1. For someone to offer one entrance to the place where they live. Mom, can I invite some friends over? I already invited Kelly over for dinner tonight—do you want to come too?

2. To visit the place where one lives despite not having been invited. Usually conveys a sense of intrusion. In this usage, a reflexive pronoun is used between "invite" and "to." Can you believe Jeanne just invited herself over and stayed for three hours? So annoying!
