Maps of Thailand and Isaan ...

[Marsilius]

On another topic below our dearest Moderator and Orator made a mistake regarding the Thailand 'area' of Isaan ... i.e. he referred to Isaan as being a Thailand 'province'.

Rather than calling Isaan a "province" (which, as you have convincingly explained, it isn't) or an "area" (which merely stresses its geographical coherence), there is surely a better word yet - "region". Unless that word has, in the overall structure of Thai government and administration, a specific meaning that rules it out of consideration, I'd choose it because it goes beyond the anodyne "area" by correctly implying that there are various broad cultural (including linguistic and socio-economic) characteristics that the constituent provinces of Isaan (though diverse in many detailed matters) have in common.
