Questions & Answers about yaksok siganeul malhae juseyo.

What does each part of 약속 시간을 말해 주세요 mean, grammatically?

• 약속 시간: “appointment time” (noun + noun; a compound meaning “time of the appointment”)
• 을: object marker attached to 시간 (because 시간 ends in the consonant ㄴ)
• 말해: “say/tell” in the -아/어 form from 말하다 → 말해 (하 + 어 → 해 contraction)
• 주세요: polite request “please do [that] (for me),” from 주시다 + 어요 → 주세요
• Subject (“you”) and indirect object (“to me”) are understood from context and omitted, which is normal in Korean.

Why is it 시간을 (with 을) and not 시간를 or just 시간?

• 을/를 is the object marker: use 을 after a consonant (시간 ends with ㄴ), 를 after a vowel.
• You can omit the object marker in everyday speech: 약속 시간 말해 주세요 is also natural. Keeping 을 makes it a bit clearer or more formal.

Is 약속 시간 written with a space, or can I write 약속시간?

Both are seen. In standard spacing, many noun–noun compounds are written with a space unless they’re very lexicalized. 약속 시간 (spaced) is a safe, standard choice; 약속시간 (no space) also appears often in practice. You won’t confuse anyone with either.

Why is it 말해 and not 말하여 or 말해요?

• 말하다 + 어 contracts to 말해. In the request pattern V-아/어 주세요, you need the -아/어 form, so 말해 주세요 is the right shape.
• 말하여 is grammatically correct but sounds overly formal/old-fashioned.
• 말해요 by itself is just the polite present (“[someone] speaks/says”); it’s not a request. The “please” request is specifically 말해 주세요.

What does 주세요 add compared to just 말해 or 말하세요?

• 말해: casual imperative (“say it”), fine with close friends, can sound blunt.
• 말하세요: polite imperative but still directive (“say it”).
• 말해 주세요: polite and soft request (“please tell me [do the telling for me]”). This is the most common, friendly request form to someone you don’t know well.

What’s the difference between 말해 주세요, 알려 주세요, and 말씀해 주세요?

• 말해 주세요: “Please tell (me).” Neutral, very common in speech.
• 알려 주세요: “Please let me know/inform me.” Feels natural in both speech and texting; it doesn’t imply speaking out loud.
• 말씀해 주세요: Uses the honorific noun 말씀. More respectful toward the listener (e.g., to a customer/senior). You can say 약속 시간을 말씀해 주세요 in formal settings.

Is it one word or two: 말해 주세요 vs 말해주세요?

Both spellings are acceptable because 주다 functions as an auxiliary (“do [it] for me”). Style guides often prefer a space (말해 주세요) for clarity, but you’ll see 말해주세요 everywhere, especially online. Either is fine.

Can I add 좀 to sound softer?

Yes. 좀 makes the request more gentle and natural:

• 약속 시간을 좀 말해 주세요.
• You can also say: 약속 시간 좀 알려 주세요.

Who is being told, and do I need to say “to me” (저에게/저한테)?

The subject “you” and the indirect object “to me” are understood. If you want to be explicit (or to avoid ambiguity), you can add it:

• 저한테 약속 시간을 말해 주세요.
• 약속 시간을 저에게 말씀해 주세요. (more formal/respectful)

Can I change the word order, like putting a topic marker: 약속 시간은 말해 주세요?

• 약속 시간을 말해 주세요 is the neutral order.
• 약속 시간은 말해 주세요 topicalizes “appointment time” and can imply contrast or emphasis (“As for the appointment time, please tell me [at least that]”). Use this when contrasting with other information.

Is 시간 the right word here, or should I use 시각?

Use 시간. It’s the natural, everyday choice for clock time in this context. 시각 is more formal/literary and rarely used in casual conversation; 약속 시각 sounds stiff.

How is the whole sentence pronounced naturally?

• Due to typical sound changes: 약속 시간을 ≈ “yak-ssok shi-ga-neul” (the ㅅ in 시간 tends to strengthen after 약속, so you’ll hear a tense s: “ssi-”).
• 말해 주세요 ≈ “ma-rae ju-se-yo” (the h in 해 is weak after 말, so it can sound like “마래”).
• Putting it together: roughly “yak-ssok ssi-ga-neul ma-rae ju-se-yo.”

How would I say this more casually to a friend?

• 약속 시간 말해 줘.
• Softer: 약속 시간 좀 알려 줘.

How do I make it extra polite/soft?

• 약속 시간을 말씀해 주시겠어요?
• 약속 시간을 알려 주시겠어요?
• With a softener at the start: 혹시 약속 시간을 알려 주실 수 있을까요?

Does this sound natural in texting, or should I change anything?

It’s fine, but in text people often prefer 알려 주세요/알려 줘 because you’re not literally speaking:

• 약속 시간 알려 주세요.
• For colleagues/clients: 약속 시간을 알려 주시겠어요?

Is there a simpler way to ask “What time is the appointment?” instead of “Please tell me the appointment time”?

Yes:

• 약속이 몇 시예요? (polite)
• 우리 약속 몇 시야? (casual)
• In a formal context: 약속이 몇 시입니까?

How do I say “I’ll let you know the appointment time” (me → them)?

• Neutral polite: 약속 시간을 알려 드릴게요.
• More formal/respectful: 약속 시간을 말씀드리겠습니다.
