PLEONASM names redundancy in expression: a phrase whose parts repeat rather than add. Free gift, tuna fish, general consensus. The sharper test runs on truthmakers rather than on ear: two terms make a pleonasm when a single fact makes both true, so the second carries no way of failing on its own. General and standard escapes the charge, since use and authorization get made true by different parties and can lapse apart. Rhetoric tolerates pleonasm as emphasis; a controlled vocabulary cannot, because a term adding no failure mode adds nothing to check.
