Into or 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’
