The term 'A LO-O-ONG TIME' can be described in three different ways. The first is 'EON', which is a geological time period lasting millions of years. The second is 'EONS', which is an even longer period of time, usually referring to the entire history of the universe. Finally, 'AGES' is a more general term that can refer to any long period of time, such as a century or an era. All three terms indicate a very long period of time.
