Meaning & origin

The name Kassiah is a relatively modern creation, first recorded in 1999, and has always been used for girls. It has never reached the top 1000 ranks, maintaining a low but steady presence. Its peak year was 2006, and recent data shows a stable trajectory with no significant rise or decline. The name likely emerged as a creative spelling of Kasia or Kassia, drawing on the popularity of similar-sounding names like Aaliyah. While not widely used in any specific state, Kassiah appeals to parents looking for a distinctive, modern-sounding name with a soft, feminine sound.

Kassiah appears to be a modern coinage, likely an elaborated spelling of Kasia, which is a Polish and English diminutive of Katherine. Katherine's origin is debated, possibly from Greek 'katharos' meaning 'pure,' or from an earlier name Hekaterine. The specific form Kassiah likely emerged in the late 20th century as a creative spelling variant.
