The Yugtun or Alaska script is a syllabary invented around the year 1900 by Uyaquq to write the Central Alaskan Yup'ik language. Uyaquq, who was monolingual in Yup'ik, initially used indigenous pictograms as a form of proto-writing that served as a mnemonic in preaching the Bible. However, when he realized that this did not allow him to reproduce the exact words of a passage the way the Latin alphabet did for English-speaking missionaries, he and his assistants developed it until it became a full syllabary. Although Uyaquq never learned English or the Latin alphabet, he was influenced by both. The syllable kut, for example, resembles the cursive form of the English word good.
