Superluxurious → It is formed from "super-" (meaning above or beyond) and "luxurious" (from Latin "luxuriosus", meaning extravagant or indulgent). The word "superluxurious" describes something that is beyond ordinary luxury, indicating an extreme level of opulence or extravagance.
Think of something that is 'above' ('super-') regular 'indulgence' ('luxurious') — that's why superluxurious means extremely luxurious.
