The study of improving the human race by controlling which people are allowed to reproduce, often based on certain traits or characteristics.
Eugenics was a controversial movement that aimed to improve the genetic quality of the human population.
Eugenics is formed from "eu-" (from Greek "eu", meaning good or well) and "genes" (from Greek "genes", meaning born of or produced by). The term refers to the idea of improving the genetic quality of a human population, hence the notion of 'good birth'.
Think of 'eu-' meaning 'good' and 'genes' meaning 'born of' — this helps you remember that eugenics is about promoting 'good birth'.
