Euphemisms Definition
A Euphemism is when you substitute language that is less direct and vague for another that is considered to be harsh, blunt, or offensive.
When talking or writing about subjects that we find embarrassing or unpleasant, we often use euphemisms; rather than say that somebody has died, we might say that they 'have passed away'. Some hospitals have 'Special Clinics', where sexually transmitted infections are treated.
