Basillia is Greek in Origin.

Basillia is a rare feminine form of the Basil- names, a variant spelling of Basilia, stemming from Greek Basileios (Latin Basilius) from basileus “king.” Its meaning is “royal” or “regal,” often rendered “queenly” in feminine use.

Attested since Late Antiquity, it appears in Christian tradition via women named Basilia and the martyr Basilissa, while the renown of St. Basil the Great sustained the family of names across the Byzantine and Latin worlds. Through medieval Iberia and Italy it entered Romance usage, persisting in Spanish- and Portuguese-speaking countries as Basilia. Parallel forms thrive elsewhere: Greek Vasiliki (nicknames Vaso, Vicky), Slavic Vasilisa, and Romanian Vasilica; masculine counterparts include Basil, Basile, Vasile, and Vasily. In English, Basillia is uncommon but carries a stately, vintage tone, with approachable nicknames like Lia or Basi and an international network of cognates that highlight its enduring “royal” heritage.
