Here’s something that occasionally pops up: Is it into or in to?
Into is a preposition that tells the reader where. “Frank went into the café.” “Betty dove into the pool.”
In to is used when the where is understood—and to communicate intent. “Frank went in to order lunch.” “Betty dove in to escape the zombie horde.”
If there’s still some confusion, try reading the sentence out loud. Chances are, you’ll hear the difference right away.
