Etymology Origin:
The word "filtration" traces back to the Latin filtrum, referring to a porous material (like felt) used to strain liquids. Over time, the term evolved into Medieval Latin filtrare (to filter), later adopted into Old French as filtre. The English suffix -ation was added to denote the process, creating "filtration" to describe the act or method of purifying substances by passing them through a filter. The logic follows the physical action of separation—retaining solids while allowing liquids or gases to pass.
