Definitions for "Attributed"

when used following the author's name in the citation of a quotation, it means regarded as belonging to, written or said by, etc.; to regard as characteristic of a person or thing. A quotation cited with an author's name followed by the word attributed was not necessarily said or written by that person but is commonly regarded as the author anyway because it seems to be in their style, something they would or could have said. The main point in cases of this type of attribution is that the citation of the author is either not certain or admittedly incorrect.
