If (1), "As for the state, these two parties, under the pretence of serving it, converted it into a prize for their contention." If (2), write, "Though served in profession, the state was in reality converted into a prize for their contention by these two parties." In (1) parties is subordinated, in (2) state.
Sometimes the addition of some intensifying word serves to emphasize. Thus, instead of "To effect this they used all devices," we can write "To effect this they used every conceivable device." So, if we want to emphasize fidelity in "The business will task your skill and fidelity," we can write "Not only your skill but also your fidelity." This, however, sometimes leads to exaggerations. See (2).
Sometimes antithesis gives emphasis, as in "You do not know this, but you shall know it." Where antithesis cannot be used, the emphasis must be expressed by turning the sentence, as "I will make you know it," or by some addition, as "You shall hereafter know it."
19. Words should be as near as possible to the words with which they are grammatically connected. See Paragraphs 20 to 29. For exceptions see 30.
20. Adverbs should be placed next to the words they are intended to affect. When unemphatic, adverbs come between the subject and the verb, or, if the tense is compound, between the parts of the compound tense: "He quickly left the room;" "He has quickly left the room;" but, when emphatic, after the verb: "He left, or has left, the room quickly."1 When such a sentence as the latter is followed by a present participle, there arises ambiguity. "I told him to go slowly, but he left the room quickly, dropping the purse on the floor." Does quickly here modify left or dropping? The remedy2 is, to give the adverb its unemphatic place, "He quickly left the room, dropping &c," or else to avoid the participle, thus: "He quickly dropped the purse and left the room," or "He dropped the purse and quickly left the room."
21. "Only" requires careful use. The strict3 rule is, that "only" should be placed before the word affected by it. ...
1 Sometimes the emphatic Adverb comes at the beginning, and causes the transposition of an Auxiliary Verb, "Gladly do I consent."
2 Of course punctuation will remove the ambiguity; but it is better to express oneself clearly, as far as possible, independently of punctuation.
