Aleithiah is in Origin.
Rooted in Greek aletheia "truth," from a- "not" + lethe "forgetfulness, concealment," Aleithiah is a modern elaboration of the classical Aletheia/Alethea. The core name entered English in the 16th–17th centuries as a learned virtue name, appreciated by both Puritans and the aristocracy; a notable bearer was Lady Alethea (Aletheia) Talbot, Countess of Arundel. The meaning evokes "unconcealed truth" or "truthfulness."
Aleithiah adapts the base with a contemporary -iah ending, giving it a biblical-tinged look without changing the Greek meaning. It remains rare, appearing sporadically in late 20th–21st century use in English-speaking countries. Close variants include Alethea, Aletheia, Alethia, Alithea, Aleithia, and Aleitha; short forms and nicknames include Thea, Letha, and Lettie. Common pronunciations mirror Alethea: uh-LEE-thee-uh or ah-LAY-thee-uh; Aleithiah is often rendered uh-LEE-thee-ah. Parents choose it for its luminous virtue sense and distinctive, lyrical profile.
Aleithiah does not appear in any of the birth registries or name datasets we track. This usually means it's either extremely rare, a regional/traditional name not captured by official statistics, or a brand-new coinage. Use it knowing your child will almost certainly be the only one in the room.
