Euphemism is a polite expression used in place of a rude, harsh, or embarrassing statement to avoid offending or humiliating someone. Euphemisms are made up of three Greek morphemes meaning "good voice act/result" and are used to soften expressions like "died" to "passed away" or describe someone as attending "remedial classes" rather than being "corrective". Common euphemisms include replacing "garbage man" with "sanitation engineer", calling the elderly "senior citizens" rather than "old people", and referring to pregnancy as being "in the family way".
