Kasiya is Polish, Slavic in Origin.

Kasiya is a modern cross‑cultural given name, most often feminine, that draws on two older roots. It aligns with Hebrew Keziah/kezia (from a word for the cassia tree) and with Greek/Latin Cassia, both evoking the fragrant “cinnamon” spice and, by extension, sweetness and warmth. The form also echoes Polish Kasia, the familiar diminutive of Katarzyna (Katherine), adding an alternate pathway to the meaning “pure.”

In use, Kasiya reads like a contemporary elaboration - Kasia + the expressive -ya ending - found in English-speaking countries from the late 20th century onward. Its deeper story reaches back to the Book of Job, where Keziah is one of Job’s daughters, and to the 9th‑century Byzantine abbess and hymnographer Kassia/Kassiani. Related variants and spellings include Kasia, Kassia, Cassia, Keziah, Kezia, Kasiyah, and Kasyah. Compact nicknames include Kasi and Sia.
