Visitor, caller, guest, visitant are terms for a person who comes to spend time with or stay with others, or in a place. A visitor often stays some time, for social pleasure, for business, sightseeing, etc.: a visitor at our neighbor's house. A caller comes for a brief (usually) formal visit: The caller merely left her card. A guest is anyone receiving hospitality, and the word has been extended to include anyone who pays for meals and lodging: a welcome guest; a hotel guest. Visitant applies especially to a migratory bird or to a supernatural being: a warbler as a visitant.
