Etymology: The past participle "diluted" comes from the Latin "dīluere," meaning "to wash away," built from "dis-" (apart) and "luere" (to wash). Its root is the same one that gives English "lave," meaning to wash or bathe, and "deluge," a great washing-away of water. So the idea at the heart of dilution is literally washing something apart until it loses its strength. Latin "dīlūtus," the form the English word descends from, carried that sense of washing out and dissolving. Over time the physical picture of water flooding over something gave way to the chemical and figurative sense of thinning a substance by adding more liquid, and then to the broader idea of anything weakened in force or quality.
