Many believe that something similar to the Jargon existed before European contact — without European words in its vocabulary. There is some evidence for a Chinookan-Nuu-chah-nulth lingua franca in the writings of John Jewitt and in what is known as the Barclay Sound word-list, from the area of Ucluelet and Alberni. Others believe that the Jargon was formed in the great cultural cauldron of the time of Contact and cannot be discussed separately from that context, with an appreciation for the full range of the Jargon-speaking community and its history.
