Aeon

Ancient Greek concept

The word aeon, also spelled eon, originally meant "life", "vital force" or "being", "generation" or "a period of time", though it tended to be translated as "age" in the sense of "ages", "forever", "timeless" or "for eternity". It is a Latin transliteration from the ancient Greek word ὁ αἰών, from the archaic αἰϝών meaning "century". In Greek, it literally refers to the timespan of one hundred years. A cognate Latin word aevum or aeuum for "age" is present in words such as longevity and mediaeval.
