The term 'kind of address' can refer to four different types of addresses. An email address is a unique identifier for an email account, typically consisting of a username and a domain name. A KEYNOTE address is a speech given at a special event, such as a conference or graduation ceremony. An INAUGURAL address is a speech given by a newly elected leader, usually at the beginning of their term. Finally, a RETURN address is the address printed on the back of an envelope or package, which is used to indicate where it should be sent if it cannot be delivered.
