This study offers a critical investigation of the ethical, phenomenological, and communitarian dimensions of the gift by bringing Marcel Mauss’s theory of reciprocity into dialogue with Edmund Husserl’s phenomenology of intersubjectivity. Through this interdisciplinary encounter, the research illuminates the moral horizons and ontological structures that underpin the very notion of giving. Using a library-based research design and a hermeneutic, conceptual-phenomenological methodology, the study engages primary philosophical texts and key interpretive commentaries to reveal how the act of giving forms a moral and ontological matrix in which otherness contributes to the constitution of selfhood and the conditions of human co-existence. The analysis and discussion were guided by Phenomenological Ethical Relationality Theory, which emphasizes the interplay between self, other, and communal lifeworld’s in the emergence of moral meaning. Findings show that the gift transcends economic exchange, disclosing a lived intentionality rooted in empathy, responsibility, and communal interdependence. By integrating classical phenomenology with African communitarian ethics—particularly Ubuntu and Ujamaa—the study demonstrates that giving is a moral necessity that sustains personhood, strengthens social harmony, and grounds ethical life in reciprocal relationality. The study concludes that a phenomenology of the gift reorients ethics and socio-economic practice toward generosity, mutuality, and shared human flourishing. The paper recommends further exploration of gift game theory to model reciprocity in ethical and social systems, and proposes extending the concept of the gift to ecological relations, envisioning environmental sustainability as an act of moral reciprocity toward the earth and future generations.
