A pseudonym is a fictitious name used by an individual, often an author, to conceal their true identity. Writers like Mark Twain and George Orwell adopted pseudonyms to create a distinct persona or to separate their personal lives from their literary work. This practice allows for greater creative freedom and can help avoid unwanted attention. Pseudonyms can also be used in various fields, such as music and art, where artists may choose a stage name or alias. This can enhance their brand or appeal to specific audiences, allowing them to express themselves without the constraints of their real names.
