The word "Gentilism" has its origins in Latin. It comes from the Latin word "gentilis", meaning "of or belonging to the same family or clan" or "of the same nation". In medieval Latin, the term evolved to refer specifically to "one who is not a Christian" or "a pagan". From there, the word entered Middle English as "gentilisme" in the 14th century, and later transformed into "Gentilism" as it is known today.
