Questions & Answers about ohu 6sie samusireul tteonayo.

What does 오후 6시에 consist of, and how does each part work?

• 오후: “PM” or “in the afternoon.”
• 6시: “six o’clock.” Here, 시 is the counter for hours.
• -에: the time particle meaning “at.” We attach -에 to specific time points.

Why is the hour expressed with a Sino-Korean number in 6시, and could you use a native-Korean number instead?

• Clock hours always use Sino-Korean numbers (일시, 이시, 육시, etc.).
• Native-Korean numbers (하나, 둘, 셋…) are used for counting items or durations (e.g. 한 시간, 두 시간) but not for the o’clock marker.

Why is 사무실 followed by -을 in 사무실을 떠나요? Can we use -에서 instead?

• 떠나다 (to leave/depart) is treated as a transitive verb here, so its “place of departure” takes the object marker -을/-를.
• You can say 사무실에서 떠나요 (treating 떠나다 more intransitively), but 사무실을 떠나요 is the idiomatic choice.
• By contrast, verbs like 나가다 (to go out) normally use -에서: 사무실에서 나가요.

What’s the difference in nuance between 떠나요, 나가요, and 퇴근해요 when talking about leaving the office?

• 떠나다: “to depart/leave” – neutral, formal enough for general use.
• 나가다: “to go out” – focuses on the act of stepping outside.
• 퇴근하다: “to leave work/clock out” – specifically ending your workday.
  Examples:
  • 오후 6시에 사무실을 떠나요 = I depart the office at 6 PM.
  • 오후 6시에 사무실에서 나가요 = I go out of the office at 6 PM.
  • 오후 6시에 퇴근해요 = I get off work at 6 PM.

What speech level is 떠나요, and how could I make it more or less polite?

• 떠나요 uses the 해요체 (polite informal) level, recognizable by the -요 ending.
• More formal: 떠납니다 (합니다체).
• Less formal (casual/반말): drop 요 → 떠나.

How would you say “I leave the office at 6 PM” in casual (반말) Korean?

• 오후 6시에 사무실을 떠나.
• You can even drop 오후 in casual chat if context makes it clear: 6시에 사무실 떠나.

How can I change 떠나요 to past or future tense?

• Past: 떠났어요
  → 오후 6시에 사무실을 떠났어요 (I left the office at 6 PM).
• Future (planned): 떠날 거예요 (polite) or 떠날 거야 (casual)
  → 오후 6시에 사무실을 떠날 거예요 (I will leave the office at 6 PM).

Why is there no subject in the sentence? How do you know who is doing the action?

• Korean often omits the subject when it’s clear from context.
• If you need to specify “I,” add 저는 or 제가:
  → 저는 오후 6시에 사무실을 떠나요.

Can I rearrange the word order—e.g. 사무실을 오후 6시에 떠나요 or 떠나요 오후 6시에 사무실을?

• You can say 사무실을 오후 6시에 떠나요, but it’s more natural to put time first (오후 6시에 사무실을 떠나요).
• The verb must come last; 떠나요 오후 6시에 사무실을 is ungrammatical in standard Korean.

Does 떠나요 here imply a habitual action or a scheduled future event?

• The present tense -아요/어요 form in Korean can express both:
  • Habitual (“I usually leave at 6 PM.”)
  • Scheduled near future (“I’ll leave at 6 PM.”)
• Context (e.g. conversation about your routine vs. tomorrow’s plan) clarifies which.
