formal
In daily conversation, "formal" is often used as the opposite of "casual." For example, wearing a suit is formal, while wearing jeans is casual. When talking about language, "formal English" refers to the way people speak or write in professional settings, such as business emails or academic essays, where slang and contractions (like "don't" or "can't") are usually avoided. Be careful not to confuse "formal" with "official." While a formal request follows strict rules of etiquette, an official request is one that comes from a person in authority.
