The term 'xenophobe' is a modern construction built from ancient Greek components. The first element, 'xeno-', originates from the Greek word xenos, which carried a complex meaning encompassing "stranger," "guest," and "foreigner," reflecting the ancient social relationship with outsiders. The second element, '-phobe', derives from phobos, the Greek personification of fear and panic, meaning "flight" or "terror." When combined in the late 19th to early 20th century, these parts logically create the meaning "one who fears the stranger or foreigner." The word's formation follows a clear Greco-Latin model used in scientific and psychological terminology, where a classical root specifies the object of the fear indicated by the suffix '-phobe'.

Structure: xeno (foreign, strange) + phobe (one who fears) - xeno: From Greek xenos, meaning "foreign, strange, guest." Acts as a combining form in English. - phobe: From Greek -phobos, meaning "fearing," from phobos "fear, panic, flight." Acts as a noun-forming suffix denoting a person with a specific fear.
