"Variant of Alexandria"
The name Xandria is commonly a female name from the "Greek" origin.
Xandria is a variant of Alexandria with the opening syllable dropped and the Greek letter xi kept as an X, the same way the shorter forms Xander and Xandra render it. It belongs to the Alexander and Alexandra family of names rather than to a separate root.
Alexandria means "Truthful one.".
The pronunciation of Xandria is ZAN-dree-uh.
