50 Tips for Writing.

47. Split infinitives

Good writers occasionally split infinitives to create emphasis, achieve a better wording order or to and avoid confusion. If splitting an infinitive makes it better for you to achieve a clearer meaning, then split away. If you have split infinitives lingering everywhere and they're plain nonsense, listen to your grammar check's sensibility and let it suggest ways for you to fix the mistakes. Emphasizing everything will make the effect useless. If you run spell check, sometimes natural already made split infinitives will show up. If that's the case, re-read your sentence, see if you can format it another way. If not, keep the structure but if you can alternative spilt infinitives, that's a good thing to do for more smoother writing.
