The process or result of being gradually decomposed.
* 1895 , H. G. Wells, The Time Machine Chapter X
A deterioration of condition.
- I fancied at first the stuff was paraffin wax, and smashed the jar accordingly. But the odor of camphor was unmistakable. It struck me as singularly odd, that among the universal decay , this volatile substance had chanced to survive, perhaps through many thousand years.
* bacterial decay
* orbital decay
* particle decay
* radioactive decay
To deteriorate, to get worse, to lose strength or health, to decline in quality.
# (intransitive, electronics, of storage media or the data on them) To undergo , that is, gradual degradation.
# (intransitive, computing, of software) To undergo , that is, to fail to be updated in a changing environment,so as to eventually become legacy or obsolete.
# (intransitive, physics, of a satellite's orbit) To undergo prolonged reduction in altitude (above the orbited body).
- The pair loved to take pictures in the decaying hospital on forty-third street.

(of organic material) To rot, to go bad.
- Damaged on lift-off, Skylab was left in orbit until its orbit decayed .
(intransitive, transitive, physics, chemistry, of an unstable atom) To change by undergoing fission, by emitting radiation, or by capturing or losing one or more electrons.

- The cat's body decayed rapidly.
(intransitive, transitive, physics, of a quantum system) To undergo , that is, to relax to a less excited state, usually by emitting a photon or phonon.
To cause to rot or deteriorate.
- Uranium decays to radium through a long series of steps with a cumulative half-life of 4.4 billion years.
- The extreme humidity decayed the wooden sculptures in the museum's collection in a matter of years.
- Infirmity, that decays the wise.
The act of destroying.
The results of a destructive event.
- The destruction of the condemned building will take place at noon.
- Amid the seemingly endless destruction , a single flower bloomed.
