New house or bright
Zaivion is a modern American invention, likely created by blending the Basque-derived Xavier with the popular '-ion' suffix found in names like Zion or Orion. It carries the associated meanings of 'new house' from its Xavier roots and 'highest point' from its phonetic connection to Zion.
