The best case is a syllabary with how the word was pronounced a few years previous.

> Around 1809, ... Sequoyah began work to create a writing system for the Cherokee language. ... He worked on the syllabary for twelve years before completion and dropped or modified most of the characters he originally created.

> After the syllabary was completed in the early 1820s, it achieved almost instantaneous popularity and spread rapidly throughout Cherokee society.[4] By 1825, the majority of Cherokees could read and write in their newly developed orthography. ...

> Albert Gallatin ... believed [the syllabary] was superior to the English alphabet in that literacy could be easily achieved for Cherokee at a time when only one-third of English-speaking people achieved the same goal.[6] He recognized that even though the Cherokee student must learn 85 characters instead of 26 for English, the Cherokee could read immediately after learning all the symbols. The Cherokee student could accomplish in a few weeks what students of English writing might require two years to achieve.
