Lexical research is a fundamental part of studying the Khitan scripts and their underlying language. This article examines selected lexical items from the Epitaph of Yelü Yugulin Taishi through comparative philology and textual analysis. Building on established decipherments, it clarifies the meanings of targeted terms and explores their etymological origins. The study aims to interpret obscure expressions in the epitaph, provide lexical references for its in-depth comprehension, and contribute to research on the genetic affiliation between Khitan and related languages.
