Etymology: Aloysius is a given name, not a common noun, and its history runs through a surprisingly long chain of languages. It is a Latinized form of "Aloys," a name from Occitan, the language of southern France. Occitan "Aloys" is itself a variant of "Louis," so the name is essentially the Latin dress of a familiar French royal name, which traces back to the Germanic name "Hludwig," meaning roughly "famous fighter." Because "Aloys" and "Louis" descend from the same source but reached English along different routes, they count as doublets, two forms of one word that entered a language separately. "Louis" carried the French royal line into English, while "Aloysius" took on Latin endings because the name was used in ecclesiastical and scholarly settings, most famously for the Jesuit saint Aloysius Gonzaga, whose Latinized name spread widely through Catholic Europe.
