This article deals with the etymology of the name of the city of Curitiba, capital of the Brazilian state of Paraná.
The meaning of Curitiba is well-established among scholars. It signifies "pinhal" or "pinheiral" (lit. 'pine forest' or 'pine grove'), reflecting the landscape that surrounds the city. The primary subject of debate lies in the language of origin of this toponym. Aryon Rodrigues, in an academic article, argues that it ultimately derives from Old Guarani, albeit exhibiting significant influences from the General Language spoken by mestiços originating from São Paulo or Rio de Janeiro. Eduardo de Almeida Navarro, while concurring with Rodrigues regarding the meaning, specifies this language as the Paulista General Language.
