I walk up Calle Durango, towards Glorieta de Los Insurgentes. Until later this day, I will mis-pronounce the word “Calle” (and a variety of other words) every time — in Spanish, “ll” has a phonetic “y” sound. Spanish words, when spoken natively, meld into a sonic river that is both soft and staccato — kind of an auditory singularity. Compared to the harsh, Germanic notes of English it is very beautiful to listen to.
