Variant of Zeline or Celine, from Latin 'caelum' meaning 'heaven' or 'sky'.
Zelline is a variant of Zeline or Celine, ultimately from Latin caelum, meaning heaven or sky. That gives the name a lifted, airy association, and the spelling adds a modern decorative gloss to an already elegant sound family.
Celine and related names have long felt refined and softly celestial, and Zelline keeps that atmosphere intact. As a given name, Zelline feels light, graceful, and slightly futuristic. It has enough familiarity to seem accessible, but the initial Z gives it extra sparkle and individuality. The result is a name that feels both elegant and contemporary, with a sky-like openness that suits its etymological roots.
