Gracious
Shaiann is a modern American phonetic variant of Cheyenne, the name of an Algonquian people of the Great Plains. While the tribal name likely means 'people of a different language,' the spelling variant Shaiann is often associated with the name Jane or Shae, leading to the interpretation of 'God is gracious.' It represents a contemporary blend of indigenous heritage and modern creative spelling.
