Queen's English refers to the standard form of British English traditionally spoken by the British royal family and the upper class. It is characterized by its clear pronunciation, precise grammar, and a specific vocabulary that often differs from other English dialects.
This form of English is often associated with a certain level of education and social status. While it is not the only way to speak English in the UK, it serves as a model for formal communication and is sometimes used in media and literature to convey a sense of authority or tradition.
