Superabsorbent → It is formed from "super-" (meaning above or beyond) and "absorbent" (from Latin "absorbere", meaning to suck in). The word "superabsorbent" describes a material that can absorb much more than usual, going beyond normal absorption capabilities.
Think of something that can absorb 'beyond' ('super-') what is typical — that's why superabsorbent materials can take in much more liquid than regular ones.
