Xenodocheinology is the study of hospitality, particularly in the context of how different cultures and societies extend welcome or reception to outsiders or guests. The term combines Greek roots meaning "to receive" (xeno) and "hospitality" (dochein). This field examines the social, cultural, and psychological implications of hospitality practices and how they shape interpersonal relationships and community dynamics. It can also explore the ethical dimensions of welcoming others in an increasingly globalized world.
