English UsageGrammar guide

In vs. Into

In usually describes position within an area or container, while into usually marks movement or direction from outside to inside. Some movement verbs allow either in or into with little or no difference, so the distinction is useful but not absolute.

Quick answer

Use in mainly for position; use into mainly for movement or direction toward the inside. Some verbs allow either form, so check the construction rather than applying an absolute rule.
