The spoken Yuchi language has changed over time, in part due to relocation. In 1885 in an article in "Science", Swiss linguist Albert S. Gatschet wrote about various linguistic idiosyncrasies in Yuchi. He said that adjectives are not expressed with number, but nouns are, by the addition of the particle "ha" (coming from the original term "wahále", meaning "many"), which made the word essentially plural. He also said that the language was no longer in an archaic state due to the lack of a "dual," and that the language had temporal and personal inflection. Gatschet did much field study and documentation regarding the language. Many of his original vocabulary lists can be found at the National Anthropological Archives or on their website.
