Describing something that spreads out or moves from one area to another, often in a gradual way.

Diffusive → It is formed from "dis-" (meaning apart) and "fundere" (meaning to pour). The word describes the action of pouring apart or spreading out.
Think of something that 'spreads out' ('dis-') like pouring water ('fundere') — that's why diffusive means spreading out.
