What does dehumanization mean?
Dehumanization is the process of denying the humanity of an individual or group — treating people as objects, animals, numbers, or enemies rather than as full human beings with dignity, feelings, and rights. The word pairs the prefix 'de-', indicating removal, with 'human', tracing its roots to the Latin 'humanus' meaning human or humane. Although the practice it describes is ancient, appearing wherever slavery, conquest, or caste systems have flourished, the term itself emerged in the 19th century and gained prominence through scholarship on the Holocaust, colonialism, and modern conflict. Today it is used chiefly in formal and academic contexts — history, psychology, law, and human-rights advocacy — where it carries a strongly negative connotation. Scholars note that dehumanization typically precedes mass atrocity: propaganda first portrays victims as less than human, making cruelty psychologically easier. Understanding the word is essential for recognizing the rhetorical patterns that historically signal danger.
nounThe process or act of depriving a person or group of human qualities, personality, or dignity, treating them as though they were less than human. It is most often discussed in relation to war, propaganda, slavery, and systemic oppression.
- The act or process of depriving individuals or groups of their human qualities, dignity, or individuality.
- A psychological state in which a person comes to perceive others as lacking human attributes such as feelings, agency, or moral worth.
"Propaganda posters during the war relied on the dehumanization of the enemy to make violence seem acceptable."
"Historians trace the genocide to years of systematic dehumanization in official rhetoric."
"Prisoners described the dehumanization of daily life under the regime, where even their names were replaced by numbers."
"Social psychologists study how dehumanization allows ordinary people to justify cruelty toward out-groups."
Rare; the word is almost always used as an uncountable mass noun referring to a general process. A plural form exists but appears mainly in academic texts discussing multiple distinct instances.
"The study compared dehumanizations across three historical conflicts."
The word entered English only in the 19th century, yet the act it names — reducing people to things — is as old as slavery itself.

Etymology of dehumanization
Dehumanization derives from the verb 'dehumanize', formed in English from the prefix 'de-' (indicating reversal or removal) plus 'human', which traces back through Old French to the Latin 'humanus', meaning 'of or belonging to people, humane, cultured'. The noun 'dehumanization' arose in the early 19th century, alongside related formations such as 'humanization'. Cognates sharing the Latin root include 'humane', 'humility' (from 'humilis', 'lowly'), and 'inhuman'; French has 'déshumanisation' and German 'Entmenschlichung' as parallel coinages.
