The development of “bijiao (比较)” from a relative degree adverb into an absolute degree adverb is syntactically reflected in several changes: it no longer requires a contrastive context, can occur in negative constructions, can co-occur with degree complements, and may itself be preceded by an absolute degree adverb. Semantically, its evolution follows a trajectory from entity comparison to category comparison, and ultimately to degree modulation. This process is driven by multiple factors, including the ellipsis and pragmatic inference, the intersubjective demands of communication, and the compensation and redistribution within the system of degree adverbs. It is further shaped by mechanisms such as contextual absorption, reanalysis, and metonymy-driven processes of decategorization and categorization. Overall, this development represents a gradual shift along the continuum formed by the comparative and degree categories, accompanied by a functional transition from externally relational expression of degree to internally scalar ones. Consequently, the function of “bijiao” evolves from a marker of comparative superiority to a modulator of scalar degree, while also acquiring pragmatic functions such as avoidance of absolutization.
