“In much of Argentina, where Lionel Messi lived until he was 13, native speakers replace the ‘y’ sound with a ‘sh’ sound. Yo, the personal pronoun for ‘I,’ becomes ‘sho,’ and calle, which other Spanish speakers would pronounce ‘ka-yay,’ becomes ‘ka-shey.’ The sound gives Argentine Spanish a slurry softness that resembles aspects of the Portuguese spoken in Brazil. More important to this story, that ‘sh,’ and the fact that Messi has retained it all his life, has at times been the sole lifeline between the greatest soccer player in the world and the country he plays for.” NY Times
