whoever, whosoever

quicumque: quaecumque; quisquis: quaequae. ☞ These pronouns take the indicative, not the subjunctive, in direct and independent clauses; it is a false refinement of modern Latin writers to use the subjunctive, for example, in such cases as the following: quamcunque doctrinae partem sibi examinandam sumsisset (Ruhnken) for sumserat; quicunque appeterent (Muretus) for appetebant; quidquid aetas reliquerit (Muretus) for reliquit (Krebs).
