In the fields of sociology and political science, authority is the legitimate power that a person or a group of persons possess and practice over other people.[1] In a civil state, authority is made formal by way of a judicial branch and an executive branch of government.[2]

In the exercise of governance, the terms authority and power are inaccurate synonyms. The term authority identifies the political legitimacy, which grants and justifies the ruler’s right to exercise the power of government; and the term power identifies the ability to accomplish an authorized goal, either by compliance or by obedience; hence, authority is the power to make decisions and the legitimacy to make such legal decisions and order their execution.[3] 

to have authority people would have to put any weight on what you have to say, if you just walk up and start talking shit without any preface or argument you're going to look like a complete tool
