IPA: /ˌpjuːtrɪˈfækʃən/
KK: /pʊtrəˈfækʃən/
The process of organic matter breaking down, especially proteins, by bacteria and fungi, which often produces a bad smell.
The putrefaction of the food left out in the sun created a terrible odor.
Putrefaction → It is formed from "putrefacere" (from Latin, meaning to make rotten) which combines "putris" (meaning rotten) and "facere" (meaning to make or do). The word describes the process of something becoming rotten or decayed.
Think of something that is 'made rotten' — 'putris' means rotten and 'facere' means to make. This helps you remember that putrefaction refers to the process of decay.
