When Jane authored the first Grammar Tip on this subject in 2009, her intention was to provide simple, concise guidance on the most commonly encountered uses of the words into and in to. But she knew that at some point we would need to explore this topic in more depth. Since issuing that Grammar Tip, we have responded to 247 questions from readers on a wide variety of situations regarding the use of into vs. in to! So, there is no better time than now to go into more depth on this topic.
How does one know when to use into or in to?
1. One of the main uses of the preposition into is to indicate movement toward the inside of a place.

Mom drove the car into the garage.
2. Into can indicate “in the direction of.”

3. Into can refer to a state or condition.

4. Into can indicate occupation or involvement.
The couple went into farming.
Unfortunately, her brother got into drugs.
5. Into can imply introduction, insertion, or inclusion.

6. Into can indicate a point within time or space.

As you can see, there are many different situations where it is correct to use the word into. However, sometimes the words in (adverb) and to (preposition) just happen to find themselves neighbors, and they must remain separate words.
