Non-verbal communication plays a fundamental role in the

expression of agreement and disagreement in English, shaping interaction

beyond the spoken word. Drawing on theories of face (Goffman, 1967),

preference organization (Pomerantz, 1984), politeness strategies (Brown,

Levinson, 1987), and contextualization cues (Gumperz, 1982), this article

investigates how multimodal signals contribute to alignment and

opposition. The analysis highlights six main channels of non-verbal

communication: gestures, facial expressions, gaze, posture, proxemics,

and paralinguistic features. Findings suggest that agreement is typically

realized through immediacy and convergence, including nodding, smiling,

sustained gaze, forward posture, reduced distance, supportive intonation,

and rhythmic synchrony. Disagreement, conversely, is characterized by

delay, withdrawal, and divergence, such as gaze aversion, backward

posture, crossed arms, softer or slower speech, and hesitancy markers. In

cases of strong opposition, emphatic gestures, loudness, and falling

intonation reinforce the stance. The integration of multiple channels

reveals that meaning is negotiated not by words alone, but by the

integration of multimodal cues. This underscores the need to view

communication as an embodied practice where non-verbal behavior is

indispensable for interactional success. The study contributes to

pragmatics and conversation analysis by demonstrating how agreement

and disagreement are managed through coordinated non-verbal resources,

with implications for intercultural communication and language pedagogy.
