This study investigates the English extra-clausal appearance construction it seems as a discourse-sensitive resource for epistemic stance, integrating insights from Systemic Functional Linguistics and Interpersonal Pragmatics. Using corpus data from COCA, BAWE, and MICASE, the analysis explores how evidential, modal, and subjective meanings are shaped by discourse context—particularly mode and register—and by speakers’ relational strategies. Four semantic-pragmatic categories—perceptual, circumstantial, generic, and conjectural—are identified and situated along a continuum ranging from experiential to epistemically marked uses. Personalization through to me clusters overwhelmingly in conjectural contexts, highlighting its role as a stance-taking strategy that foregrounds subjectivity while mitigating face-threat. The study provides an empirically grounded account of it seems as a flexible interpersonal construction shaped by contextual, epistemic, and relational work. The findings contribute to our understanding of how grammatical constructions function within discourse to manage epistemic stance and interpersonal alignment.
