IntroductionSilence is a part of all interactions, yet its potential significance within medical education remains underexplored. Existing literature primarily focuses on its use as a skill, leaving a gap in understanding its broader implications. Emerging evidence from higher education suggests that conceptualising silence as a way of being and becoming could enrich personal and professional growth. Unfolding dialogue on equality, diversity and inclusion suggests that silence on inequity can be oppressive. However, medical education has yet to consider the possible implications of conceptualising silence in this way.MethodsWe explore silence through the philosophical lens of acknowledgement. Acknowledgement—communicative behaviour that grants attention to others—is a philosophy with roots in phenomenology. It is concerned with being and becoming, and silence can be part of the communicative behaviour that constitutes acknowledgement. Our aim in exploring the ontological nature of silence (silence associated with being) using acknowledgement is to offer a springboard for practitioners, educators, and researchers to consider how silence is connected with our existence as people.ResultsPositive acknowledgement involves a commitment to turning towards the other and valuing this connection. Silence can be a way of demonstrating this—for example, giving patients the space they need to express their thoughts and emotions. Negative acknowledgement is the opposite and involves dismissing, ignoring or invalidating another's experiences. In the context of silence, negative acknowledgement may involve ignoring a person or group's ideas, or bystander silence when witness to discrimination.ConclusionsWithin this work, we consider the ramifications of conceptualising silence as ontological, rather than purely a skill to be taught. This is a novel way of conceptualising silence, and there is a pressing need to explore this further to expand our understanding of the impact of silence for diverse groups of learners, educators, practitioners and patients.
