I think you may be confusing the etymology of a word, i.e., where it came from, with its meaning as used by the speakers of a language. Here's a definition from a commonly cited online dictionary of American English: > eugenics > : the practice or advocacy of controlled selective breeding of human populations (as by sterilization) to improve the population's genetic composition https://www.merriam-webster.com/dictionary/eugenics#dictionary-entry-1 https://www.merriam-webster.com/dictionary/eugenics#dictiona... Here's another definition from the Oxford Dictionary of English Third Edition: > eugenics | juːˈdʒɛnɪks | > plural noun [treated as singular] > the study of how to arrange reproduction within a human population to increase the occurrence of heritable characteristics regarded as desirable. Developed largely by Sir Francis Galton as a method of improving the human race, eugenics was increasingly discredited as unscientific and racially biased during the 20th century, especially after the adoption of its doctrines by the Nazis in order to justify their treatment of Jews, disabled people, and other minority groups.
