Stuck on the distinction between “in to” and “into”? You’re not alone! Don’t worry, though, I’ve got you covered.
You have probably come across the phrases me either and me neither in both writing and conversation. Have you ever wondered which is correct? Let’s look at the grammar behind these expressions. Note that unlike pairs such as either vs. Neither, these two phrases don’t have precise meanings. Although widely used, they are idiomatic as. Dive onto the bed. Dive on to the bed. (This is wrong because 'to the bed' is not the prepositional phrase. The prepositional phrase is 'onto the bed.' ) Dive on to sleep for an hour. (This one is correct because 'to' marks the infinitive verb 'to sleep.' In other words, 'to' has its own role to play in the sentence.) Move on to the next chapter. However, onto is more or less the standard form in US English and in the specialized mathematics sense. Nevertheless, it is important to maintain a distinction between the preposition onto or on to and the use of the adverb on followed by the preposition to: she climbed on to (or onto) the roof but let's go on to (not onto) the next point.
The quick version:
Into vs. In To
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.”

“In To” vs. “Into” Is Hard Because of Phrasal Verbs
A phrasal verb is a verb made of two words. There are several phrasal verbs that contain “in,” and this is the beginning of all our troubles.
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
Plural word of tidy. 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:
In Vs On Grammar
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?
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.”
Into Is a Preposition
Past form of cook. Apart from phrasal verbs, into and in to are pretty easy to figure out.
Into is a preposition, which means it denotes a location, and in this case, a movement toward a location.
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.”
