Is the country México or Méjico? addresses the spelling of the noun México. However, it does not address the pronunciation. I have heard México pronounced both as if it was written with a "x" (as English speakers pronounce it) and as if it were written with a "j". To make things more complicated, some old Spanish words written with an "x" were in fact pronounced as if they were written with a "j" (which is what was addressed by the Royal Academy of the Spanish Language that changed the spelling of words in 1754, as far as I understand).
So, my question is:
- In which countries people more predominantly pronounce México with the "x" sound and which ones pronounce it with a "j" sound, regardless of the spelling?
- How was the noun México pronounced historically? Was it originally pronounced with the "j" sound and then evolving, in some countries, to be pronounced with an "x" sound because of its spelling?
