Questions & Answers about dubuneun naengdongsire neoheo dumyeon orae ga.

What does 두부는 mean here, and why use 는 instead of 가/이?

두부는 marks tofu as the topic of the sentence. Using 는 often means “as for tofu…” and can imply a general statement or contrast (e.g., tofu vs. other foods).

• 두부는 = “As for tofu / tofu (in general)…”
• If you used 두부가, it would sound more like you’re focusing on tofu as the specific subject doing something (less “general tip” vibe), and it can feel less like a general rule/advice.

Why is 냉동실에 used, and what does 에 mean?

에 marks a destination/location where something is put or exists.

• With 넣다 (to put in), 에 is the standard particle for “into”: 냉동실에 넣다 = “put (it) into the freezer.”
• 냉동실 specifically means the freezer compartment, not the fridge in general.
