The term 'has permission' can be summarized by the three-letter word 'MAY'. This word is used to indicate that someone has the authority or right to do something. It is often used in the context of asking for permission to do something, such as 'MAY I go to the store?' or 'MAY I borrow your pen?'. It can also be used to indicate that something is allowed or permissible, such as 'You MAY leave now' or 'You MAY not enter this area'.
