Without A Doubt

毋庸置疑( it is certain ... )

We say "without a doubt" to express that something is certain. "Without a doubt" is often used as a response to a yes-no question. Example: "Are you going to watch the game tomorrow?" Answer: "Without a doubt!" Without a doubt stresses that the speaker strongly believes in the positive response. Example: "Each candidate believes he is without a doubt more qualified to lead the country."
