The name Osias is a boy's name of Greek origin meaning "salvation". Osias and is often added to lists like If You Like Oscar, You Might Love.... and discussed in our forums with posts like "Hunt for our favourite boy names (Alphabet-wise)".
From the experts:
Osias has a Latinate and biblical feel without making an appearance in the Bible. The related Ozias, on the other hand, is a form of Uzziah, found in the Greek and Latin Old Testament, and could make a distinctive path to the nickname Oz or Ozzie--both far cooler, in our opinion, than Oswald.
