is less common. Word-final intervocalic s-aspiration is more frequent in northern Argentina. For example, esto es lo mismo "this is the same" is pronounced something like , but in las águilas azules "the blue eagles", in las and águilas might remain as no consonant follows: , or become : . The phoneme (written as before or , and as elsewhere) is never glottalized to in the Atlantic coast. That phenomenon is common to other coastal dialects in Latin American Spanish, but not the Rioplatense dialect. Rioplatense speakers always realize it as . In some areas, speakers tend to drop the final sound in verb infinitives and the final in most words. This elision is considered a feature of uneducated speakers in some places, but it is widespread in others, at least in rapid speech. Many Argentinians merge into , meaning that "unsociable" and "uranium" are pronounced the same. is a relatively common allophone of .

This correlates well with immigration patterns. Both Argentina and Uruguay have received large numbers of Italian settlers since the 19th century. According to a study conducted by National Scientific and Technical Research Council of Argentina Buenos Aires and Rosario residents speak with an intonation most closely resembling Neapolitan. The researchers note this as a relatively recent phenomenon, starting in the beginning of the 20th century with the main wave of Southern Italian immigration. Before that, the porteño accent was more like that of Spain, especially Andalusia, and in case of Uruguay, the accent was more like Canarian dialect.
