Lost in Translation

The name of the market struck me as unusual and strange.   
Sub meaning below, or poor quality.

Searching through the internet I found Permsap used frequently for names of villas.
I'm told the Permsap means 'more money.' 




Never been quite satisfied with the translation of Sakon City.
Supposedly it means city of cities.
Interestingly the Facebook translation of Sakon City is Sapphire City

The translation at You Tube for สกลนคร is also Sapphire
