How it's used
This is a formal idiom often used in professional settings, news reports, or serious discussions to emphasize certainty. While it functions as an adjective, it is rarely used to describe simple, everyday objects, appearing more frequently when discussing abstract concepts like ability, intent, or facts. Using it in casual conversation can make you sound overly dramatic or like you are reading from a script.
Examples
