What does brainwashing mean?
Brainwashing refers to the deliberate, sustained manipulation of a person's mind so that they abandon their existing beliefs and adopt new ones imposed by another party. Unlike ordinary persuasion, it implies coercion through techniques such as isolation, sleep deprivation, repetition, fear, and total control of information, leaving the subject unable to think critically about what they have come to believe. The word entered English during the 1950s, translated from the Chinese expression xǐnǎo ('wash the brain'), amid Western concern over prisoners of war in Korea who appeared to adopt their captors' ideology. Today the term is used most seriously in discussions of cults, authoritarian regimes, and coercive interrogation, though it also appears loosely — and sometimes hyperbolically — to describe intense advertising or partisan media. Because it carries strong negative connotations and implies manipulation rather than genuine conviction, calling something brainwashing is usually a serious accusation. Related forms include the verb 'brainwash' and the adjective 'brainwashed'.
The process of systematically pressuring someone into abandoning their beliefs and accepting imposed doctrines, typically through isolation, repetition, and psychological coercion.
"Survivors of the sect described decades of brainwashing that made them distrust everyone outside the group."
Usually uncountable; when countable, it appears as 'a form/kind of brainwashing'.
Informally and often hyperbolically, any persistent one-sided persuasion regarded as unfairly dominating someone's thinking.
"He joked that twenty years of corporate training had turned into pure brainwashing."
This figurative sense is informal and can sound dismissive or exaggerated.
Rarely used; brainwashing is almost always treated as an uncountable mass noun. When a plural sense is needed, speakers prefer phrases such as 'acts of brainwashing' or 'cases of brainwashing'.
"The report documented several cases of brainwashing carried out by the organization."
The English word 'brainwashing' is a direct translation of the Chinese term 'xǐnǎo' (literally 'to wash the brain'), coined during the Korean War era to describe how prisoners of war seemed to change their loyalties.

Etymology of brainwashing
Brainwashing entered English in the early 1950s as a literal translation — a calque — of the Mandarin term xǐnǎo (洗脑), meaning 'to wash the brain', which was used to describe ideological re-education in China. Journalist Edward Hunter popularized the English term in his 1950 reporting on the Korean War, where it was applied to American prisoners of war who seemed to embrace communist ideology. The first element comes from Old English 'brægen' (brain) and the second from the Germanic root behind 'wash'; despite its recent coinage, both components are ancient native English words. Its formation by translation rather than borrowing makes it a rare example of a modern calque entering mainstream vocabulary.

The noun carries strongly negative connotations and is frequently used in debates about cults, totalitarian regimes, advertising, and media influence; because it implies coercion rather than mere persuasion, applying it figuratively can sound accusatory or exaggerated. It functions primarily as an uncountable mass noun, though it occasionally takes an indefinite article ('a form of brainwashing'). The verb 'brainwash' is more common in everyday speech than the noun itself.
