Ouija

Ouija (pronounced wee-juh (sometimes wee-jee (US)))

(1) An instrument in the shape of a board on which is written the alphabet, the numbers 0-9 and the words "Yes", "No" & "Goodbye" (with occasional additions), the characters selected by a small, heart-shaped piece called a planchette.  Board is used during a séance to contact spirits of the dead, the characters selected by the participants collectively placing their hands on the planchette which is then guided by the spirit(s) to the appropriate letter or number.

(2) As Ouija board, a small-scale replica of an aircraft carrier's flight and hangar decks, installed in the in the flight control room and manually updated with scale models as a communications fail-safe.  Used in every US carrier since WWII (although now in the throes of being replaced by electronic versions).

1891: A trademark name granted to the Kennard Novelty Company (US), a compound of the from French oui (yes) and the German ja (yes).  Oui is from the Old French oïl, a compound of o (the affirmative particle) and il (he), akin to o-je (I), o-tu (thou), o-nos (we) and o-vos (you), all ‘yes’ constructed with pronouns.  O and òc are both from the Latin hoc (this) and may correspond to the Vulgar Latin construction hoc ille.  Ja is from the Middle High German ja, from Old High German jā (yes), from Proto-Germanic ja from the primitive Indo-European yē (already).  It was cognate with the Dutch ja, the English yea (yes) and the Latin iam (already).

Although Ouija, as a propriety brand-name, dates only from 1891, similar boards existed in China from circa 1100 BC and have long been part of occult and spiritual practice in the west, attaining great popularity in the mid-nineteenth century and again during WWI and its aftermath.
