How Regional Dialect Affected the Transformation of the name "Seokdo" to "Dokdo"

Some Japanese scholars have insisted that the island cited as "Seokdo" in the Korean Imperial Ordinance Number 41 of October 25, 1900 is not the present day island known as Dokdo.   Many of the residents of Ulleungdo came from Cholla Province in Korea, and their dialectal variety of Korean transformed the word "Seokdo" to "Dokdo".   The following is a list of place-names from Cholla Province that have also had their names transformed by the dialectal pure Korean of that region. All of the following examples below show the Cholla dialectal version, Dok, and the more common Sino-Korean version of the same place-name, Sok, in parentheses.
