"Variant of Jeremiah"
The name Ermias is commonly a male name from the "Hebrew" origin.
Ermias is the Amharic and Tigrinya form of Jeremiah, the name of the biblical prophet, which entered Ge'ez and Amharic usage by way of the Greek Ieremias and ultimately the Hebrew Yirmeyahu. It is an established personal name in Ethiopia and Eritrea. Its appearance in United States birth records does not mark the invention of the name, only its arrival in this particular data set.
Jeremiah means "Praised highly by God, Exalted by God.".
The pronunciation of Ermias is er-MEE-ahs.
