segregation
[C/U] Both
This term carries a heavy emotional and political weight, particularly in the context of human rights and social justice. It describes a forced, structural division that creates a hierarchy of power and access, evoking images of barriers, separate entrances, and systemic exclusion. In technical or scientific settings, the word is neutral and descriptive. It refers to the physical sorting of materials or the biological separation of cells, where the goal is purity or organization rather than social control.
Countable when referring to specific instances or types of separation, such as gender segregation in a school. Uncountable when referring to the general concept or political system of dividing people.
