Alitheah is Greek in Origin.

Alitheah is a contemporary English variant of Alethea/Alithea, ultimately from Greek Alētheia (Αλήθεια), meaning “truth,” from a- “not” + lēthē “forgetfulness/hiddenness.” The form subtly evokes Thea (“goddess”) and Leah, giving it familiar sound while preserving the classical sense of “truth, sincerity, unconcealed.”

The name Alethea entered English use in the 17th century amid interest in classical virtues; it was borne by Alethea Howard, Countess of Arundel, and appeared among Puritans who favored virtue names. Usage waned and then revived in the 19th–20th centuries with renewed taste for Greek-derived names. Alitheah itself is rare and modern, functioning as an embellished or phonetic spelling. Close variants include Alethea, Alithea, Alethia, Aletha, and Letha; internationally it appears as Alethea or Aléthéa (rare). Nicknames and short forms include Thea, Ali, Leta/Letha, and Lettie. Overall meaning: “truthful; one who reveals truth.”
