As an English teacher, I have been creating content for both Korean learners and global English learners. This blog is where I share the grammar rules I cover in my lessons — and today’s quiz is about two words that look almost identical but mean something very different: in and into.
No rules first. Just the quiz. 👇

Now let’s check! 🎉
Q1: b) into “She walked into the room.” → INTO = movement from outside to inside (she was outside, now she’s inside)
Q2: b) in “He is sitting in the car.” → IN = already inside, no movement (he’s already there)
Q3: b) into “The cat jumped into the box.” → INTO = movement (the cat moved from outside the box to inside)
Q4: b) in “I left my keys in the kitchen.” → IN = location, no movement (the keys are just sitting there)
Q5: b) into “She poured the water into the glass.” → INTO = movement (water moved from outside to inside the glass)
The simple rule 🔍
- IN = already inside, no movement → state
- INTO = moving from outside to inside → action
Ask yourself: is something moving or staying? Moving → INTO Staying → IN
