authoritative

What does "authoritative" mean?
"Authoritative" describes something that commands respect, possesses high reliability, or comes from an expert source. Imagine a judge’s gavel or a textbook written by a leading scientist; it carries an inherent weight that makes people want to listen and believe because it is grounded in deep knowledge or legitimate power. In usage, this word is positive, implying confidence and expertise, unlike "authoritarian," which implies control and oppression. You will often see it paired with words like "source," "tone," or "figure." It suggests that the person or information provided is the definitive standard by which others should be measured.
