Dark, black, or mountain range
Cierrah is a modern creative spelling of Sierra or Ciara. It draws from the Spanish word for a mountain range with jagged peaks and the Irish name Ciara, meaning dark-haired or dark-complexioned. This specific spelling adds a decorative 'h' and is much rarer than its traditional counterparts.
