The term "formal" refers to a style or manner that adheres to established rules, conventions, or traditions. It is often associated with events or occasions that require a specific dress code, such as weddings or business meetings. In these settings, people typically wear suits or dresses to convey respect and seriousness. In communication, "formal" can describe language that is structured and polite, often used in professional or academic contexts. For example, a research paper or a business email usually employs formal language to ensure clarity and professionalism. This contrasts with informal language, which is more casual and conversational.
