The word "filth" originates from Old English fȳlþ, derived from fūl (meaning "foul") + the noun-forming suffix -þ (modern "-th"). The root fūl is shared with the modern word "foul," reflecting a longstanding association with dirt, decay, or moral corruption. Over time, the spelling evolved to "filth," but the core meaning of repulsive uncleanliness—both literal and figurative—remained intact.
