Mountain range or black
Cierria is a modern creative spelling of Sierra, which is the Spanish word for a mountain range. It is also frequently associated with the Irish name Ciara, meaning dark or black-haired. This specific spelling variation gained some traction in the United States during the late 20th century but remains rare.
