Questions & Answers about gonghangeseoneun heubyeoneul mos haeyo.

Why do we have both 에서 and 는 in 공항에서는?

• 에서 marks the place where an action happens (“at/in” for activities).
• 는/은 is the topic particle; here it makes “as for at the airport” and often implies contrast (e.g., “At the airport, you can’t smoke (even if elsewhere you might)”).
• Without 는, 공항에서 흡연을 못 해요 is also correct, just less contrastive.

Can I use 공항에 instead of 공항에서? What’s the difference between 에 and 에서?

• 에: location of existence or destination (used with verbs like 있다/없다, 가다/오다).
• 에서: location where an action/event occurs.
• Smoking is an action, so you need 공항에서, not 공항에.

Is 공항에서는 the same as 공항에선?

Yes. 에선 is the contracted form of 에서는. It’s common in speech and informal writing; both are correct.

Why is there a space in 못 해요? Is 못해요 wrong?

• When 못 is the adverb “cannot,” write it separately from the verb: 못 가요, 못 먹어요, 못 해요.
• In the fixed pattern -지 못하다, it’s written together: 하지 못해요, 피우지 못해요.
• You’ll see 못해요 informally, but as a learner, prefer the spaced form when it’s just 못 + verb.
