Alethia is Greek in Origin.

Alethia is an English feminine given name from Greek Aletheia (Αλήθεια), “truth,” literally “unconcealment.” It entered English as a virtue name in the 16th–17th centuries, when classical and moral qualities were favored, and was often spelled Alethea; Alethia is a later and still established variant. The meaning grounds the name in clarity, sincerity, and candor.

Usage is documented among the English aristocracy and Puritan families (e.g., the 17th‑century Aletheia Talbot, Countess of Arundel), then revived in the Victorian era and carried to America, where Alethia appears in 19th‑ and early 20th‑century records. Today it is uncommon but recognizable. Close forms include Alethea (standard English), Aletheia (direct Greek), Aletha, and the rarer Alathea; nicknames include Thea, Allie, and Letha. Not to be confused with Althea, which derives from a different Greek root meaning “healer.”
