Yupik

This term functions as both an ethnonym and a glottonym. When referring to the people, it is used as a proper noun to denote a specific indigenous cultural identity. When referring to the language, it functions as an uncountable noun, similar to other language names like English or Spanish.

Because it is a proper noun derived from a specific ethnic group, it is always capitalized. In linguistic contexts, it is often specified as Central Alaskan Yup'ik or Siberian Yupik to distinguish between different dialects and regional variations.
