Principe Huahua — in Santiagueño Quechua.

Santiago del Estero Quichua or Santiagueño Quechua (Santiagen Quichua) is a vulnerable dialect of Southern Quechua spoken in the province of Santiago del Estero in Argentina. Long-standing migration has also resulted in the presence of the language in other provinces of northeastern Argentina and in Buenos Aires.

It is 81% similar to other Quechuan languages. Its speakers are Native Americans and they mostly work in agriculture. It is the third most widely spoken indigenous language.

There was once another dialect of Southern Quechua in Argentina, that of Catamarca and La Rioja, but it has gone extinct. All were introduced during the Spanish colonial period, as Quechua speakers were transplanted to various parts of the Spanish realm (continuing a practice of the Inca), and Quechua was an official language of Santiago, Catamarca, and La Rioja during the colonial era.
