de·cay′er n.Synonyms: decay, rot, decompose, putrefy, spoil, molder, disintegrate
These verbs refer to the gradual process by which something breaks down or falls apart as a result of natural causes. Decay has wide application but often suggests partial deterioration short of complete destruction: "A decaying dam is an accident waiting to happen" (George Black).
Rot and decompose are closely synonymous with decay, but rot often emphasizes loss of structural integrity while decompose generally stresses breaking down into chemical components: The rotting timbers gave way under the added weight. When grass clippings decompose, they return nutrients to the soil.
Putrefy denotes an advanced stage of organic breakdown that is offensive to the senses: "Large numbers of cows and oxen ... were left to putrefy on mud flats after the floods receded, attracting rats" (John F. Burns).
Spoil usually refers to the process by which perishable substances become unfit for use or consumption: Fish will spoil quickly if not refrigerated.
To molder is to crumble to dust: The shawl had moldered away in the trunk.
Disintegrate refers to the reduction of something to particles, fragments, or constituent elements: The sandstone façade had disintegrated from exposure to wind and rain.
