Garner 2003 (†878)Garner, Bryan A. Garner's Modern American Usage (Oxford University Press, 2003).
- evidence (s.v. "evidence" (p. 322)): Testimony is a species of evidence; it refers only to evidence received through the medium of witnesses. Evidence, the broader term, includes all means by which a fact in issue is established or disproved; thus evidence may include documents and tangible objects. . . . Strictly speaking, [evidence and proof ] are not synonymous. Unlike evidence, the word proof applies to the effect of evidence, not to the way in which truth is established. (†2637)
