authority
uh-THOR-i-tee
/ɔːˈθɒrəti/
An accepted source of expert information or advice; a person with undisputed expertise.
While 'authority' can mean power or government control, in the context of expertise, it refers to a person whose knowledge is so respected that their statements are accepted as definitive truth.
The story behind the word. The word authority is deeply connected to the word 'author.' In ancient Rome, an 'auctor' was someone who brought something new into the world—a creator, builder, or writer. Because they created it, they were naturally trusted as the ultimate source of knowledge about it.
