Hello native English speakers. 1. Though we may detest him, we must acknowledge his greatness. 2. No matter how much we detest him, we must acknowledge his greatness. 3. Detest him as we may, we must acknowledge his greatness. 4. Detest we him as we may, we must acknowledge his greatness. Question A: Which is grammatically correct? I guess all are grammatically correct except sentence 4. However, my grammar book states that sentence 4 is also correct. Furthermore, it points out that the concessive adverbial structure introduced by "as" can also form a complex sentence containing an object clause. When the subject of the main clause and the (object) clause are both the same personal pronoun, the subject of the main clause is often omitted. Question B: Look and sentences 4 (4. Detest we him as we may, we must acknowledge his greatness.), here, my question is: Notice the first "we" in sentence 4, which , according to my grammar book, indicates that the first"we" here is the subject of the main clause. Then what is the object clause here?
