History & Origin

Casia is chiefly a spelling of Cassia, a Greek name for the fragrant cassia spice, a cinnamon relative, giving it a soft, botanical feel. For some families it may instead echo Kasia, the Polish pet form of Katarzyna. Both routes are plausible, which we note. A girl named Casia near its faint peak in the late two-thousands is a teenager or young adult now.

It rose gently with the wider fashion for warm, plant-inspired names but never became common. The double-S Cassia remains the more familiar spelling.

Did you know? Cassia is a real spice, a cousin of cinnamon, so the name carries a warm, botanical scent along with its old Greek roots.
