Understanding Split Infinitives in English Grammar

In English grammar, a split infinitive is a construction in which one or more words come between the infinitive marker to and the verb (as in to really try  my best). Also called a cleft infinitive. A  split infinitive  is sometimes regarded as a type of tmesis. I think the evidence is conclusive enough, says editor Norman Lewis: it is perfectly correct to consciously split an infinitive whenever such an act increases the strength or clarity of your sentence (Word Power Made Easy, 1991). Examples and Observations Here are some examples of split infinitives, and descriptions of the term and its uses from other texts to help you better understand their function: To deliberately split an infinitive, puristic teaching to the contrary notwithstanding, is correct and acceptable English.(Norman Lewis, How to Speak Better English.

Stanford University Press, 2001 A 19th-Century Proscription Hostility to the practice of splitting infinitives developed in the nineteenth century. A magazine article dating from 1834 may well be the first published condemnation of it. A large number of similar prohibitions followed. The first to call it a split infinitive was a contributor to the magazine Academy in 1897. (Henry Hitchings, The Language Wars. John Murray, 2011) A False Analogy With Latin The only rationale for condemning the [split infinitive] construction is based on a false analogy with Latin. The thinking is that because the Latin infinitive is a single word, the equivalent English construction should be treated as if it were a single unit. But English is not Latin, and distinguished writers have split infinitives without giving it a thought. Noteworthy splitters include John Donne, Daniel Defoe, George Eliot, Benjamin Franklin, Abraham Lincoln, William Wordsworth, and Willa Cather. Still, those who dislike the construction can usually avoid it without difficulty. (The American Heritage Dictionary of the English Language, 4th edition, 2000)The split-infinitive rule may represent mindless prescriptivisms greatest height. It was foreign. (It was almost certainly based on the inability to split infinitives in Latin and Greek, since they consist of one word only.) It had been routinely violated by the great writers in English; one 1931 study found split infinitives in English literature from every century, beginning with the fourteenth-century epic poem Sir Gawain and the Green Knight . . .. (Robert Lane Greene, You Are What You Speak. Delacorte, 2011) Clarity and Style In fact, an unsplit infinitive may be less clear than a split one, as in He decided to go boldly to confront his tormentor, where it is unclear whether boldly is attached to go or confront or perhaps both. (Jean Aitchison, The Language Web: The Power and Problem of Words. Cambridge University Press, 1997)The condemnation of  the split infinitive  seems so devoid of adequate justification that, personally, I am accustomed to look upon it as merely idiosyncratic. The use of the idiom can be defended on various grounds, not the least substantial of which is the need of allowing language that freedom from purely artificial restraints which it continually and successfully claims. . . .Adverbs of one or two syllables readily adhere to the verb as prefixes, and thus disguise their reprobate individualities. But it is generally assumed that there is no glue strong enough to make such processional words as circumstantially, extraordinarily, disproportionately, and the like,  stick withi n  the split infinitive,  and therefore they must  be trailed after  verbs like cartloads of bricks. The majority of the adverbs in common use, however, do not attain such unwieldy dimensions, and  may  well be admitted within  the split infinitive,  especially if  clarity  of apprehension is promoted  thereby. And  surely the idiom is not to be pilloried if it serves to make the sentence more harmonious—as, for instance, in He decided to rapidly march on the town, where to march rapidly is certainly less pleasing to the ear. From such considerations as these I therefore infer that  the split infinitive  does not merit the censure which critics frequently bestow on it.  (J. Dormer, Split Infinitive. Notes and Queries, January 21, 1905) The Lighter Side of Split Infinitives Would you convey my compliments to the purist who reads your proofs and tell him or her that I write in a sort of patois which is something like the way a Swiss waiter talks, and that when I split an infinitive, God damn it, I split it so it will stay split.(Raymond Chandler, letter to Edward Weeks, Jan. 18, 1947. Quoted by F. MacShane in Life of Raymond Chandler, 1976)
