Thande said:Mexico is an Aztec name*, albeit the way it's spelled and pronounced in OTL is influenced by Spanish.
So in TTL the name might well still be Mexico, but Diamond might have transliterated it differently to emphasise the difference - what would that look like in Arabic transliterated to our alphabet? Mikhikou, perhaps?
*I think it refers to 'Mexicoatl', the Aztec god of death, or something?
Mikhikou sounds good
