"Form of Cheyenne"
The name Chyanne is commonly a female name from the "Native American" origin.
Chyanne is a respelling of Cheyenne, an English given name taken from the name of the Cheyenne people, a Native American nation of the Great Plains. The spelling changes the vowel of the middle syllable; the name itself is the same one, not a new coinage or a blend of two elements.
Cheyenne means "An Algonquian tribe of the Great Plains. Capital city of Wyoming.".
The pronunciation of Chyanne is shy-AN.
