Old Korean
The boundaries of Old Korean periodization remain in dispute. Linguists sometimes classify the poorly understood languages of the Three Kingdoms of Korea as variants of Old Korean, while others reserve the term for the language of Silla alone. Old Korean traditionally ends with the fall of Silla in 935. This too has recently been challenged by South Korean linguists who argue for extending the Old Korean period to the mid-thirteenth century, although this new periodization is not yet fully accepted. This article itself focuses on the language of Silla before the tenth century.
