Meaning & origin
Letha is a name that enjoyed modest popularity in the early 20th century, with its peak year in 1903. Despite falling out of regular use since then, its trajectory has been stable, with occasional renewals of interest. The name's etymology is unclear, but it may be connected to the Greek concept of truth through Alethea. Letha has a soft, vintage sound that appeals to those seeking a rare and simple name. While it never reached top-tier popularity, its historical usage offers a glimpse into naming trends of the era.
Letha is of uncertain origin. It may be a variant of Leta, which could derive from the Greek name Alethea, meaning 'truth'. Alternatively, it might be a short form of names such as Letha itself or a feminine form of Leith.
