What does decaying mean?
"Decaying" is the present participle and gerund of the verb "decay," describing something in the process of gradual deterioration. In its most literal sense it refers to the decomposition of organic matter — fruit, leaves, wood, flesh — broken down by bacteria and fungi. By extension it applies to buildings, cities, and infrastructure crumbling into disrepair, and more abstractly to declining values, institutions, health, or influence, as in "a decaying empire." The word carries a connotation of slow, often irreversible decline rather than sudden collapse, which gives it a melancholy or critical edge in literary and journalistic use. It derives, via Old French, from the Latin "decadere," meaning "to fall away," making it a sibling of words like "decadence" and "cadence." Its versatility across physical, social, and abstract registers makes it an essential word for describing entropy in both nature and civilization.
Undergoing gradual rotting, decomposition, or decline.

Etymology of decaying
"Decaying" comes from "decay," which entered English from Old North French "decaïr," itself derived from Late Latin "decadere" — formed from "de-" (down, away) and "cadere" (to fall). The same Latin root "cadere" produced English words such as "cadence," "cascade," "accident," and "chance," all sharing the underlying sense of falling. The verb has been part of English since at least the late Middle Ages, with its participial form following regular modern conjugation.
