USAGE NOTE: Fact has a long history of usage in the sense allegation of fact, as in This tract was distributed to thousands of American teachers, but the facts and the reasoning are wrong (Albert Shanker). This practice has led inevitably to the introduction of the phrases true facts and real facts, as in The true facts of the case may never be known. These usages may occasion qualms among critics who hold that facts cannot be other than true, but they often serve a useful purpose.
