The Greek prefix a- and suffix -ios work together like our ending “less.” It appears in the Greek words for “harmless,” (akeraios), “blameless,” (anaitios), and “unprofitable” (achreios). More generally, -ios turns nouns into adjectives. So, it literally means "ageless". -- (CW) "Everlasting" is an adjective based on the word that means "age" or "eon." It has the sense of "perpetual" or "ageless." It doesn't really means "eternal or "everlasting" as we used those words today.  See this article. CW - Confusing Word -- The "eternal everlasting" does not capture the specific meaning of the word.
