IPA: /ˌɛkspərˈɡeɪʃən/
KK: /ɛkˈspɜrɡeɪʃən/
The process of removing unwanted or harmful parts from something, especially in written texts, to make it more acceptable or appropriate.
The expurgation of the book removed all the offensive language.
Expurgation → It is formed from "ex-" (meaning out) and "purgare" (meaning to cleanse or purify). The word refers to the act of cleansing or removing undesirable elements from something, often in the context of texts or literature.
Think of 'cleansing' something by removing what is 'out' ('ex-') — that's why expurgation means to cleanse by removing unwanted parts.
