Splitting infinitives is done so frequently today that it sounds more natural. Consider:
"I was hoping to completely finish the project before the teacher called on me"
From the Oxford A–Z of Grammar and Punctuation by John Seely:
split infinitive
The infinitive is the form of the verb made by adding to to its stem:
to go
Some traditionalists say that you should never place anything between the to and the stem. They argue that since the infinitive is a part of the verb it should never be split. So it is wrong to say to boldly go. You should instead say to go boldly or boldly to go.
There is no grammatical justification for this so-called 'rule', and people have been splitting infinitives for centuries. Indeed sometimes it is impossible to convey your meaning unless you do split an infinitive. For example:
Everyone else thought they were too young to really cope with adult responsibilities.
If you move really to another position you change the meaning of the sentence:
Everyone else thought they were too young really to cope with adult responsibilities.
Everyone else thought they were too young to cope really with adult responsibilities.
I was hoping to finish the project completely
before the teacher called on me.
I agree that sometimes splitting infinitives sound better, but it happens less often than most people think, and to my ear, this is certainly not one of the cases.
I'm old-fashioned this way, but split infinitives are like nails on chalk to me. I try to avoid using adverbs, but if an adverb is necessary, I try to place it after the verb it is modifying, not before.
Another recent habit is the infinitive split with a negative: "I asked him to not do that any more," rather than: "I asked him not to do that any more."
An unsplit negative can sometimes lead readers down a garden path, but that usually indicates a need to rethink the sentence, for example to reframe it without a negative: "I asked him to stop doing that."
