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."[10] 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 remedy[11] 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 strict[12] rule is, that "only" should be placed before the word affected by it.*
The following is ambiguous:
"The heavens are not open to the faithful only at intervals."
The best rule is to avoid placing "only" between two emphatic words, and to avoid using "only" where "alone" can be used instead.
In strictness perhaps the three following sentences:
(1) He only beat three,
(2) He beat only three,
