sierra
Synonym discussion
Sense: noun/1
Sierra, mountain range, cordillera, and ridge all describe groups or lines of mountains, but differ in scale, shape, and usage. Sierra specifically implies jagged, saw-like peaks and carries a cultural connection to regions with Spanish influence. Mountain range is the most general and neutral term — a traveller could use it for the Rockies, the Alps, or the Himalayas. Cordillera is a more technical, large-scale term for a system of parallel mountain ranges, such as the American Cordillera that runs from Alaska to Chile. Ridge is narrower, referring to a single long crest rather than a chain of peaks. 'The hikers crossed the sierra into the next valley' uses the precise word for jagged terrain, while 'the mountain range stretched across the horizon' works in any context.

Etymology
Sierra comes from Spanish, where it originally meant 'saw' — the cutting tool with sharp teeth on its edge. Spanish explorers in the 16th century began using the word to describe mountain ranges whose jagged peaks reminded them of a saw's teeth. The fish sense developed later, also named for its saw-like dorsal fin.
