Etymology: "Filtrated" is the past tense and past participle of "filtrate," a verb meaning to pass a liquid through a filter so that the clear liquid, the filtrate, is separated from solids. Its own pedigree is a New Latin coinage: "filtrātus," meaning "filtered," is the past participle of the New Latin verb "filtrō," "to filter." That verb is built from "filter" with the verb-forming suffix "-ate," the same ending found in words like "activate" and "separate." The sense of entering quietly through a gap or restricted area, which the definition here gives, is a figurative extension of the physical idea. Water passing through a porous barrier, leaving impurities behind, suggests people or information slipping past checkpoints or screens in much the same way.
