An authoritative statement is a declaration that carries weight and is usually issued by someone in a position of authority. The term can be broken down into three parts: MANDATE (7 letters), DICTA (5 letters), and FIAT (4 letters). A MANDATE is an official order or command, usually from a higher authority. DICTA is a formal pronouncement or authoritative statement. FIAT is a formal authorization or an order issued by a person in authority. Together, these three terms describe an authoritative statement that carries weight and is issued by someone in a position of authority.
