According to Kory Stamper, a writer of (of all things) dictionaries at Merriam-Webster, there’s no logical basis for a law that says it’s wrong to wantonly split an infinitive. Even more startling, I can even pick any preposition I like to end a sentence with! And, as if that weren’t enough, its historically and grammatically consistent to drop the apostrophe from the “it-is” contraction and to put one in it’s possessive.
Just another sign that the world of order and certainty is crumbling into chaos! Definitely a good time to practice living in the not knowing.
