split an infinitive

Insert between particles

To split an infinitive is to insert a word, usually an adverb, between "to" and a verb: to boldly go, to really understand.

Traditional grammar rules prohibited this construction, but the prohibition has largely faded.

Most contemporary usage guides consider split infinitives acceptable when they sound natural, and avoiding them can produce awkward phrasing.
