Meaning & origin
Aletheia, a name drawn from ancient Greek philosophy, embodies the concept of truth. First recorded in U.S. data in 1973, it has never been common but has gained gradual traction, rising since 1993 and reaching a peak rank of 2,895 in 2025. Its rarity is underscored by a 1-in-27,712 incidence. Geographically, it appears most often in Florida, California, and Texas, reflecting broader trends for uncommon, intellectually tinged names. Aletheia appeals to parents seeking a name with depth and a classical foundation, distinct from more familiar Greek-derived names like Sophia or Alexandra.
Aletheia comes from the ancient Greek word ἀλήθεια (aletheia), meaning truth, used in philosophical contexts by Plato and Aristotle. As a given name, it was revived in the 20th century, particularly in English-speaking countries, often chosen for its intellectual and virtuous connotations. Its use remains rare but has seen a slight increase since the 1990s.
