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.decay (dɪˈkeɪ) vb1. to decline or cause to decline gradually in health, prosperity, excellence, etc; deteriorate; waste away2.

code decayThe tendency for computer software to become gradually worse in performance or responsiveness over time, eventually leading to it becoming completely faulty, unresponsive, or unusable. This is either due to software failing to remain up to date and compatible with the operating system in which it operates, or because the software's code has been updated or altered in ways that have introduced more bugs and errors over time. (It doesn't refer to actual physical decay.) If you want to develop programs that people continue to use for years to come, you've got to factor in ways to avoid code decay with each new update, the users will eventually move on to something that works better. A lot of people just let programs sit on their hard drives for years at a time without being updated or upgraded at all, and then are totally flabbergasted when code decay renders them totally unusable down the line.See also: code, decaysoftware decayThe tendency for computer software to become gradually worse in performance or responsiveness over time, eventually leading to it becoming completely faulty, unresponsive, or unusable.

More positively, it represents the death of an old situation before rebirth into a new state.
