Aloys is a ♂ male name.
Aloys is a Provençal variant of the name Louis, which derived from the Old High German name Ludwig. Aloys could also be a Romance form of the Old High German name Alwis, but this has not been proven.
Aloys could mean “all wise” or “very wise” (from Alwis or Old High German “al” = all + “wîsi” = wise) or “famous warrior” (from Ludwig or Old High German “hlūt” = famous/loud +”wīg” = battle/war).
