Theoretical models have been proposed to revisit the conceptualization of face as a challenge to the classic politeness paradigm, among which Face Constituting Theory (FCT) (Arundale, 1999) provides a full-range model to explain and explore human facework in interpersonal communication. Based on the framework of Conjoint Co-constituting Model of Communication (Arundale, 1999), FCT conceptualizes face in terms of relational connection and separation in the interactional process between participants. In this paper, the theoretical background, the core notions, and the analytical framework of FCT are presented and reviewed, with the hope to provide implications for future research on face.
