Root Explanation

Infiltration → It is formed from "in-" (meaning into) and "filtrare" (meaning to filter). The word describes the process of filtering or permeating into a substance or area.

Think of something moving 'into' ('in-') and 'filtering' ('filtrare') through a barrier — that's what infiltration means.
