Etymology
The word 'filtration' narrates the story of a basic physical process named for its material tool. Its core, 'filtr-', descends from Medieval Latin filtrum, meaning 'felt', a porous textile made of compressed wool or hair. This material was historically used to strain liquids, giving its name to the action itself. The suffix '-ation', of Latin origin, systematically converts verbs into nouns denoting processes or results. Thus, the literal "process of using felt" evolved into the modern, abstract scientific term for any operation of separating solids from fluids using a porous medium.
