Etymology

Origin of segregation

First recorded in 1545–55; from Late Latin sēgregātiōn-, stem of sēgregātiō, from sēgregāt(us) “separated” (past participle of sēgregāre “to part from the flock”; see segregate) + -iō -ion

Explanation

Segregation is a system that keeps different groups separate from each other, either through physical dividers or using social pressures and laws. The Latin root literally means “separated from the flock,” and splitting a big flock of sheep into smaller groups is segregation. For many decades in the United States, “separate but equal” was the phrase used to describe the unjust racial segregation of black people and white people. There are harmless types of segregation as well, like "the segregation of dog food and human food in your cupboards."
