Etymology
Origin of authority
First recorded in 1200–50; earlier auct(h)oritie, from Latin auctōritās “power, influence, prestige,” equivalent to auctor “authority, originator, supporter” ( see author) + -itās -ity
Explanation
If you have the authority to do something, you have the right or power to do it. You are the big cheese. Or, if you know more about a topic than most, you are an authority on that topic. Giving someone authority grants them the power to make important decisions or have accepted opinions. When you leave your kids with a babysitter, you give her the authority to put them to bed at 7 p.m., no matter how much they insist you let them stay up until midnight. You'll feel more confident leaving the babysitter in charge of bedtime decisions if she's written two books on the subject and is an authority, or renowned expert, on children's sleep habits. Being an authority on children's sleep habits helps your babysitter enforce that 7 p.m. bedtime, but it may not convince the kids.
