Keywords: Lunfardo, Argentina, lexicon, Spanish varieties, language attitudes This investigation explores the Argentinian Spanish variety known as Lunfardo among Argentinians from the greater region of the Rio de la Plata. While texts that have served to record this lexicon date back to the late 19th century, the literature on Lunfardo is sparse in exploring its contemporary status. This study examines quantitative and qualitative data collected from speakers in order to determine the extent to which Lunfardo lexical items are recognized as distinctive from standard Argentinian Spanish, and investigates some of the attitudes of these speakers towards this historically stigmatized variety. The analysis also takes into consideration the potential influence of sociolinguistic factors in speakers' attitudes and levels of lexical recognition of Lunfardo.
