I'm almost 100% certain that the word in the question is mis-spelled. HOWEVER - the mis-spelling is so close to several other words that I do not want to make a guess as to what is being asked. FIND OUT HOW THE WORD IS SPELLED CORRECTLY AND THEN RE-SUBMIT THE QUESTION.
Expulsion refers to the act of forcing someone to leave or be removed from a place, organization, or institution. It usually occurs as a consequence of severe misconduct, violation of rules, or breaking the law. The individual who is expelled is typically no longer allowed to be a part of the group or community they were expelled from.
