[1829.] The subjunctive is used in parenthetical sentences of restriction: as,

Thus, the ordinary correlative of quī is is, less frequently hīc, ille, īdem. Similarly tot . . . quot are used as correlatives; also quō . . . eō, quantō . . . tantō; quantum . . . tantum; tam . . . quam; totiēns . . . quotiēns; tālis . . . quālis; ubī̆ . . . ibī̆; ut . . . ita, sīc, or item; cum ... tum.
