Etymology: "Moldiness" is a plain formation: the adjective "moldy" with the suffix "-ness", which turns an adjective into a noun for a state or quality. "Moldy" itself comes from "mold," the fuzzy fungal growth, and the suffix attaches to the adjective to name the condition of being covered in that growth. The noun has an older pedigree than its modern spelling suggests. Middle English had "mowldnes," a near-identical form, showing that English speakers were describing the state of mouldering things with this same construction for centuries. The word has stayed a straightforward descriptive term, which is why its parts are so easy to read.
