There is a city in Texas named Amarillo. What is the "correct" pronunciation of that city name - the Spanish way of pronouncing the word, or the way the locals say it?
Or maybe UK folks get it right?
Sequim, WA is an interesting one.
But back Spanish, the word Mexico itself I’ve heard as: \meiko\, \’mehiko\, \’meXiko\, \’meksiko\ and of course \’meksikou\
Somehow those Spaniards brought that change to /x/ to all those Nahuatl place names but they never brought /θ/ to everyday speech in Mexico. I scratch my head at that.
