Root Explanation

Adsorption → It is formed from "ad-" (meaning to) and "sorbere" (meaning to suck or absorb). The word describes the process of a substance adhering to the surface of another, as if being drawn to it.

Memory Tip

Think of a substance being 'drawn to' ('ad-') the surface and 'sucking' it in ('sorbere') — that's what adsorption means.
