Hmmm I mean more like the position that person is in, rather than an adjective: an esteemed newspaper pays the expert food critic to write a column, the reader turns to this column for guidance on a restaurant's food, it is the critic's duty to serve a knowledgeable piece of reasoned advice for the reader. If the reader hasn't heard of the critic, they can still put some faith in their views because the [position of authority] the esteemed newspaper has put them in should ideally guarantee they know their potatoes.
>>695 they do this for a living which gives them [authority on the subject] ?
