Xaby

Xaby is a diminutive or familiar form of the Basque name Xabier, which is the Basque form of Xavier. The name Xavier itself originates from the Basque place name Etxeberria, meaning 'the new house' or 'new castle'. This place name refers to the village of Javier (Xabier in Basque) in Navarre, Spain, where Saint Francis Xavier was born. The name gained widespread popularity due to Saint Francis Xavier, a co-founder of the Society of Jesus (Jesuits) and a prominent Roman Catholic missionary.

While Xabier is the traditional Basque spelling, Xavier became the more common form internationally, particularly in Romance languages. Xaby, as a short form, is a more modern and informal adaptation, primarily used in Spanish-speaking regions and among Basque communities. It carries the same historical and religious connotations as its longer form but offers a more contemporary and approachable feel.
