The 1920s saw many new words and phrases enter the English language as a result of social, technological, and cultural changes following World War 1. The economic turmoil of the postwar period led to terms like "recession" and "redundant" coming into common use. New industries like radio, film, and consumer products spawned vocabularies to describe inventions, media, and leisure activities. Discussions of topics like sex, sexuality, and relationships also expanded the language as taboos were loosening. The 1920s truly was a decade that shaped the English vocabulary through its social, political, and technological upheavals.
