When to use "In" or "Into"

Question

When will I use "In" and when will I use "Into" in making sentences? Does it have a difference? or in can be used interchangeably.

Answer 1

While they are both prepositions, they are not the same thing. See dictionary definitions in and into.

• In - used to indicate inclusion within space, a place, or limits
• Into - toward or in the direction of

Here's some examples to highlight the differences:

He is in the bar vs He walks into the bar
I'm in big trouble vs I'm heading into trouble
