evidence: Since before the foundation of the Democratic People's Republic of Korea ('DPRK' or 'North Korea') in 1948 a three-tiered system of administrative divisions has existed across the Korean peninsula. This administrative system is primarily based around provinces, counties, and villages, designated by the suffixes –do, -kun, and –ri, respectively, which serve as the basis for North Korean 'country grammar'. The territory of the modern DPRK covers four of the eight Korean provinces (조선팔도 | 朝鮮八道) dating to 1413 AD: Pyong’an, Hwanghae, Hamgyong, and Kangwon. Add –do, pronounced like Homer Simpson’s ‘doh!" sans exclamation mark to the end of each when speaking in Korean become Pyong’an-do, Hwanghae-do, Hamgyong-do, Kangwon-do.
