Reading the rest of the Act also confirms that, as relevant here, there are only two ways to set up an Exchange in a State: establishment by a State and establishment by the Secretary. §§18031(b), 18041(c). So saying that an Exchange established by the Federal Government is “established by the State” goes beyond giving words bizarre meanings; it leaves the limiting phrase “by the State” with no operative effect at all. That is a stark violation of the elementary principle that requires an interpreter “to give effect, if possible, to every clause and word of a statute.” Montclair v. Ramsdell, 107 U. S. 147, 152 (1883). In weighing this argument, it is well to remember the difference between giving a term a meaning that duplicates another part of the law, and giving a term no meaning at all.
