Why Roberts flubbed the oath: The curse of split infinitives

Among these fetishes is the prohibition against “split verbs,” in which an adverb comes between an infinitive marker like “to,” or an auxiliary like “will,” and the main verb of the sentence. According to this superstition, Captain Kirk made a grammatical error when he declared that the five-year mission of the starship Enterprise was “to boldly go where no man has gone before”; it should have been “to go boldly.” Likewise, Dolly Parton should not have declared that “I will always love you” but “I always will love you” or “I will love you always.”

Any speaker who has not been brainwashed by the split-verb myth can sense that these corrections go against the rhythm and logic of English phrasing. The myth originated centuries ago in a thick-witted analogy to Latin, in which it is impossible to split an infinitive because it consists of a single word, like dicere, “to say.” But in English, infinitives like “to go” and future-tense forms like “will go” are two words, not one, and there is not the slightest reason to interdict adverbs from the position between them.
