Into vs. In To: The Easy Information to Retaining Them Straight

Stuck on the distinction between “in to” and “into”? You’re not alone! Using the single word “into” is often misplaced with two individual words, “in” and “to.” 

In this article, you’ll learn some quick grammar rules that can help you remember how and when to use these words in the English language to avoid this common error. 

Into vs. In To

The quick version:

Use “into” to describe where something is: going inside something else.

Use “in to” based on the verb that comes before it. It can have many meanings, but here’s a quick tip that covers some of them: if you can replace it with “in order to,” use “in to.”

Into Is a Preposition

A preposition is a word that shows a relationship between words in a clause or phrase. When you consider whether or not to use into (the preposition) or in to, consider whether or not the verb is being used to place something in space or time. 

Being a preposition, into also means it denotes a location, and in this case, a movement toward a location—the preposition will have an object creating a prepositional phrase.

In most cases, into will place something inside another object, or into another space.

Example: Kerri stirred the chocolate chips into the cookie dough mix.  

Apart from phrasal verbs, into and in to are pretty easy to figure out.

It can also denote some kind of transformation.

For example: Jim turned into a car.

Remember, in this case, you wouldn’t say, “Jim turned in to a car.”

And if Jim were driving the car and not performing a Kafka-esque transformation, you wouldn’t say, “Jim turned into the driveway,” because that would mean he became a driveway. Which would be kind of weird, right?

“In To” Are Two Separate Words

“In” and “to” are two unrelated words: the adverb “in” and the preposition “to.”

Sometimes they bump into each other (by the bump into, not bump in to each other, because phrasal verbs, those pesky things). And when that happens, chaos ensues. Just remember what we talked about above, though, and you’ll be fine.

“In” and “to” can have many meanings depending on the verb that comes before “in,” but a common one is “in order to.”

“Into” vs. “In To” and Phrasal Verbs

A phrasal verb is a verb made of two words. There are several phrasal verbs that contain “in,” and this is likely why so many make this common grammar mistake.

Here are some of the phrasal verbs containing “in”:

  • Log in
  • Drop in
  • Ended in
  • Chime in
  • Turn in
  • Move in
  • Hand in
  • Join in
  • Give in
  • Get in
  • Chip in
  • Break in
  • Cut in
  • Fill in
  • Hang in
  • Let in

Here’s why this matters:

When “in” is part of a phrasal verb, it’s always “in,” not “into.” Changing it to “into,” even if the preposition would be appropriate,  would change the meaning of the verb.

Here’s an example of a phrasal verb used correctly and incorrectly:

Correct: Can you log in to your computer for me?

Incorrect: Can you log into your computer for me?

Incorrect: Can you login to your computer for me?

Another example:

Correct: I’m going to turn in to bed.

Incorrect: I’m going to turn into bed.

See, that would be weird, because unless you’re Harry Potter, transfiguring into a bed will be tough!

“Into” is also part of a few phrasal verbs, like:

  • Run into
  • Bump into
  • Break into
  • Cut into (I know both break into and cut into are also on the list above, but they have different meanings. You cut into a piece of cake but cut in on a dancing partner)
  • Look into

Here, these prhasal verbs are always “into.”
