Argentina
Buenos Aires Rioplatense Spanish is marked by sh-yeísmo — 'll' and 'y' are both pronounced with a 'sh' sound rather than the 'y' used across most of Latin America. Voseo replaces 'tú' entirely in all casual registers, with corresponding verb form shifts: 'llorás' (not 'lloras'), 'podés' (not 'puedes'), 'sentís' (not 'sientes'). Argentine Spanish clearly articulates final consonants and retains intervocalic 'd', contrasting with the consonant-weakening typical of Caribbean and some coastal Latin American dialects.
