A fact is a pragmatic truth, a statement that can, at least in theory, be checked and confirmed. Facts are often contrasted with opinions and beliefs, statements which are held to be true, but are not amenable to pragmatic confirmation.The word fact derives from the Latin Factum, and was first used in English with the same meaning: "a thing done or performed", a use that is now obsolete. The common usage of, "something that has really occurred or is the case", dates from the middle of the sixteenth century. Fact is sometimes used as synonymous with truth or reality, as distinguishable from conclusions or opinions. This use is found in such phrases Matter of fact, and "... not history, nor fact, but imagination."
