Ji Seok-yeong and Ju Si-gyeong were, until approximately 1905, scholarly collaborators who frequently referenced each other's works in the study of the Korean language and letter. However, subsequent to this period, their intellectual trajectories began to subtly but significantly diverge. Their differences extended beyond mere disagreements on isolated issues; rather, they held fundamentally opposing views on the approach to modern linguistic standardization. Ji Seok-yeong placed great emphasis on the preservation of traditional orthographic practices among language users, whereas Ju Si-gyeong advocated for a 'scientific' reform of these practices. This paper undertakes a thorough examination of the texts from the period when Ji Seok-yeong and Ju Si-gyeong were still mutually referencing each other's work. Subsequently, it delineates the specific points of divergence in their views following 1905. Through this analytical lens, the paper endeavors to assess their respective orientations towards the process of modern linguistic standardization.
