For example:
Dave walked into the store. -- Where did Dave walk? Intothe store.
"In" is also a preposition that sometimes finds itself near "to" in a sentence.
For example:
Dave walked in to buy a soda. -- Where did Dave walk? In.
In this case, "to" is an infinitive as it is followed by the simple form of the word "buy".
