Dilapidated
Etymology
From Latin "dilapidare," literally "to scatter like stones": "dis-" ("apart") plus "lapidare" ("to throw stones"), from "lapis" ("stone"). It first meant to squander or waste — as if flinging away one’s resources stone by stone — and only later settled into its modern sense of a structure crumbling into ruin.
