"Blend of Joe and Nathan"
The name Joenathan is commonly a male name from the "English" origin.
Joenathan is an English compound given name built from the two established given names Joe and Nathan, written together as a single word. Both elements have long recorded use as English given names, and the joined form appears in United States birth records from 1934. The spelling also sits close to Jonathan, but the Joe element gives the written form a distinct first syllable.
The pronunciation of Joenathan is JO-nuh-thun.
