“Langage” is the name given – in Haitian Voodoo, Voudoun or Voudoo – to the strange words in which the Loa are sometimes addressed, and which traditionally have been used also in oracular utterances from divine sources.

Some meanings would appear to have been passed on as priestly knowledge, but some appear to have been lost .

A part of the vocabulary may be made up of lost or garbled African words, part from other sources; but both African and Amerindian traditions exist of a secret oracular speech, different from that of the people.
