Last week we talked about when to use onto (one word) versus on to (two words). As promised, we’re talking about the distinction between into versus in to this week. While some of the same guidelines apply, into can be trickier because it has more definitions and different strategies for remembering which form to use.
Like onto, into (one word) is a preposition that indicates movement. But into can mean so much more.

If you’re questioning whether to use into or in to, start by determining whether the problem sentence fits into one of the definitions or examples below.
