Superfluity → It is formed from "super-" (meaning above or over) and "fluere" (meaning to flow). The word describes something that flows over or beyond what is necessary, indicating excess or surplus.
Think of something that flows 'above' ('super-') what is needed ('fluere') — that's why superfluity means an excess or surplus.
