This paper investigates a semiotic analysis of facial expressions in Tiv conversation. The aim of the seminar is to examine nonverbal communicative functions of facial expressions in Tiv conversations using Paul Ekman’s theory of universal facial expressions as a theoretical framework. While Ekman posits that certain facial expressions such as anger, joy, fear, and contempt are biologically innate and universally recognised; This study applies his model within a semiotic framework to explore how these expressions are culturally interpreted and deployed in Tiv interpersonal communication. Data were drawn from 10 respondents in naturalistic Tiv interactions and analysed semiotically to reveal how these expressions function as icons, indexes, and symbols that complement or replace verbal speech. The study identifies key facial expressions such as Duchenne smiles, furrowed brows, and jaw clenching as semiotic signs that index emotional states and social intentions. The findings reveal that facial expressions in Tiv conversations serve as structured communicative tools, functioning both as complements to speech and as independent conveyors of meaning. These expressions are used to affirm, contradict verbal statements, and they play crucial roles in emotion regulation, respect signaling, and social alignment. For instance, tightened lips often signal restrained disagreement, while a turned-away face may indicate subtle disapproval. The study further finds that although facial expressions are universal in form, their use and interpretation are deeply rooted in Tiv cultural norms, especially within age, gender, and hierarchical relationships. The research concludes that facial expressions are indispensable to Tiv discourse, functioning as a silent language of cultural performance and emotional negotiation. It recommends the inclusion of nonverbal communication in linguistic and anthropological studies of African languages and calls for the training of cultural mediators to recognise these signs. Future research should expand to include other nonverbal modalities such as gestures and eye movement across diverse Tiv-speaking communities
