Abstract This study argues that the development and functions of the Chinese pragmatic marker (PM) Xle are best understood through a constructional approach. In this construction, X (usually a monosyllabic verb or adjective) combines with le, a current relevant state marker, to form Xle, which conveys a negative evaluative stance—such as impatience, frustration, or disapproval—regardless of X’s original meaning. Repetition of Xle intensifies emotional expression rather than creating redundancy. Focusing on the diachronic development of bale, the earliest attested Xle form, the study shows how it shifted from a syntactic predicate to a stance-taking PM through reanalysis, analogy, and subjectification. Mapping Xle within a constructional network, the paper highlights how form-meaning pairings drive its multifunctionality and alignment with speaker intention. This approach offers broader insights into the emergence of evaluative stance within a dynamic linguistic system.
