The phoneme /1/ (as calle=street, apellido=last name, Have= key or caballo= horse) has disappeared in many zones of Spanish America to give place to the "yeismo", a linguistic phenomenon characterized by the predominance of the /y/ over other phonemes like /1/. Because of this, the word calle is pronounced caye, apellido=apeyido, Ilave=yave and caballo=cabayo.
