Questions & Answers about saendeuwichie chijeureul neoheumyeon deo masisseoyo.

Why is 에 used in 샌드위치에?

Because 에 marks the place or container that something goes into.

With 넣다 (to put in), a very common pattern is:

• A에 B를 넣다 = put B into A

So here:

• 샌드위치에 = into the sandwich
• 치즈를 = cheese as the thing being put in

If you translated the structure very literally, it would be something like put cheese into the sandwich.

Why is it 치즈를, not 치즈가?

Because 치즈 is the direct object of 넣다.

• 를/을 marks the thing that receives the action
• In this sentence, the action is 넣다 = to put in
• The thing being put in is 치즈

So:

• 치즈를 넣다 = to put in cheese

If you used 치즈가, the sentence structure would usually need a different verb, such as 들어가다:

• 치즈가 들어가면 더 맛있어요 = If cheese goes in / if the sandwich has cheese in it, it’s more delicious

That version is also natural, but it has a slightly different grammatical structure.
