«Chapurriau como lo han llamado siempre». Origen del glotònim xapurriau a la Franja (primera meitat del s. XX)

“Chapurrear” is defined as “to speak a language with difficulty and make mistakes” (RAE, 2023). This article examines the historical use of the term Chapurriau to refer to the language spoken within the Catalan-speaking region of Aragon (the Franja). It systematically examines its earliest recorded appearances in written public discourse and finds no evidence that Chapurriau appeared in written form before the 20th century. This absence contrasts with historical references to the language as Catalan or Limousin. The article suggests that debates over glottonyms, or clearly associated with the idea of linguistic mixture, are closely linked to its historical loss of functions and can thus be understood as symptoms of its decline.
