Putrify' is a verb which means to decay or decompose, usually in a foul-smelling manner. It is caused by the action of bacteria and other microorganisms on organic matter. Putrify is a natural process that occurs when organic matter is exposed to air and moisture, allowing bacteria and other microorganisms to break down the material. This process can be accelerated by warm temperatures and high humidity. Putrify is often associated with the smell of rotting food or garbage, as well as the smell of decaying animal or plant matter.
