Final answer:
Sequoia's Cherokee syllabary was a writing system created by a Cherokee leader, enabling the Cherokee to preserve and unite their culture through written communication.
Step-by-step explanation:
Sequoia's Cherokee syllabary is an example of a significant linguistic and cultural achievement for the Cherokee people. Sequoyah, a Cherokee leader, created this writing system despite not being able to read or write in any other language. His work took roughly a decade and resulted in a collection of symbols and characters that represented the syllables of the spoken Cherokee language, which fostered unity and literacy among the Cherokee nation. The implementation of this syllabary enabled the Cherokee to publish newspapers, official documents, and record their rituals and medicines, thus strengthening their cultural identity and providing a means to preserve their culture even after displacement.
