Circumstantial evidence: evidence obtained from circumstances, which necessarily or usually attend facts of a particular nature, from which arises presumption. According to some authorities circumstantial is distinguished from positive evidence in that the latter is the testimony of eyewitnesses to a fact or the admission of a party; but the prevalent opinion now is that all such testimony is dependent on circumstances for its support. All testimony is more or less circumstantial.

Something incidental to the main subject, but of less importance; opposed to an essential; -- generally in the plural; as, the circumstantials of religion.
