If you have two clauses joined by a pronoun that is the object of the first clause, but the subject of the second clause, do you treat the pronoun as a subject or object? That's confusing, so for instance: "I will give ten dollars to whomever/whoever mows my lawn." In this instance, "whomever" sounds better to me--an object. But by the same token, if I change the sentence just slightly, but with the exact same structure: "I will give ten dollars to him/he who mows my lawn." In this instance, "he" sounds better to me--a subject, though really nothing has changed. These are, of course, only examples, and there are other instances where this sort of dilemma comes up, and I'm just curious what the rule is as a whole. Thanks.
