Koreanic loanwords in Khitan and their importance in the decipherment of the latter

In this article I am surveying several possible loanwords from Koreanic languages (probably Koguryǒ and/or Bo-hai) into the Khitan language. Apart from explaining the origin of some of the Khitan words that have no Mongolic, other Central Asian, or Chinese etymologies, I will demonstrate that these loanwords can shed light on the decipherment of Khitan characters with unknown readings, and therefore advance the reconstruction and reading of the Khitan language itself
