Into vs. In To | Difference, Examples & Quiz
Into and in to are pronounced the same, but they have different grammatical functions.
- Into is a preposition used to indicate entry, insertion, collision, or transformation. It can also be used to say that someone is interested in or involved with something. Write “into” as one word when you mean it in one of these senses.
- In to is a combination of two separate words: the prepositions “in” and “to.” The words should remain separate when the sense is separate. For example, in the phrase “call in to see you,” the phrasal verb “call in” is separate from the infinitive verb phrase “to see you.”

Frequently asked questions
- Is it “log into” or “log in to”?
“Log in” is a phrasal verb meaning “connect to an electronic device, system, or app.” The preposition “to” is often used directly after the verb; “in” and “to” should be written as two separate words (e.g., “log in to the app to update privacy settings”).
“Log into” is sometimes used instead of “log in to,” but this is generally considered incorrect (as is “login to”).
- Is it “tune into” or “tune in to”?
“Tune in” is a phrasal verb meaning “watch a TV show” or “listen to a radio show.” The preposition “to” often comes immediately after this phrase; “in” and “to” should be written as separate words when this happens (e.g., “Tune in to the final episode next week”).
“Tune into” is sometimes used instead of “tune in to,” but this is generally considered incorrect.
