Into vs In To: What's the Difference?
Quick Answer
"Into" = movement or transformation (one word)
"In to" = "in" is part of a phrasal verb + "to" is separate (two words)
The Key Difference
INTO (one word)
Movement or transformation
"She walked into the room."
"Water turned into ice."
IN TO (two words)
Phrasal verb + infinitive/purpose
"I logged in to my account."
"She came in to talk."
Key: If there's a phrasal verb (log in, hand in, turn in, come in), keep "in" and "to" separate.
