Mountain range or saw-toothed
Cyerra is a modern creative spelling of the Spanish word 'sierra', which refers to a jagged mountain range. It gained popularity in the United States during the late 20th century as part of a trend for nature-inspired names with unique phonetic spellings. The 'Cy-' prefix adds a contemporary flair to the traditional geographic term.
