What is the origin of the name Ouija as it relates to the infamous boards of the same name?

There are many theories, none of which are confirmed. Some say it is a conjunction of the french "oui" (yes) and the german ja (also yes). Another is that it came to the inventor of the board during a seance and it is an Egyptian word that means "good luck".

What is the origin of the name Ouija as it relates to the infamous boards of the same name?
There are several theories about the origin of the term "Ouija". According to one of these, the word is derived from the French "oui" (for "yes") and the German "ja" (also for "yes"). An alternative story suggests that the name was revealed to inventor Charles Kennard during a Ouija s茅ance and was claimed to be an Ancient Egyptian word meaning "good luck." It has also been suggested that the word was inspired by the name of the Moroccan city Oujda. Despite its common usage, "Ouija" is a registered trademark[citation needed] (but the term "Ouija Board" has been abandoned as a registered trademark[citation needed]).
