Questions & Answers about yaksok siganeul mesijiro allyeo juseyo.

What does 알려 주세요 literally mean, and why use it?

It literally means “please let [someone] know.” Breakdown:

• 알리다 = to inform/notify → connective -아/어 → 알리어 → 알려
• 주다 as an auxiliary = “do it for someone” → 알려 주다 = inform (for me)
• Polite request ending -세요 → 알려 주세요 = please inform (me) This is the natural, polite way to ask someone to provide information.

Why is it 약속 시간을 with -을? Can I drop the particle?

-을/를 marks the direct object. 약속 시간 (“appointment time”) is what you want to be told, so 약속 시간을 is standard.

• In casual speech, you might hear the particle dropped: 약속 시간 메시지로 알려 주세요. It’s understandable but less careful/formal. Keep -을/를 in writing or neutral/formal speech.

What does 메시지로 mean, and why -로 not -으로?

-로/으로 marks the means or method: 메시지로 = “by/through a message.” Choice rule:

• After a vowel or the consonant ㄹ → -로 (메시지 ends in a vowel → 메시지로)
• After other consonants → -으로 (e.g., 문자 → 문자로; 카카오톡 → 카카오톡으로) Note: 메시지에/에서 would mean “in/at a message,” not “by message,” so they don’t fit here.

Can I say 문자로 instead of 메시지로? What about apps and email?

Yes. Common options:

• 문자로 = by text/SMS
• 카톡으로/카카오톡으로 = via KakaoTalk
• 이메일로 = by email
• 전화로 = by phone call Examples: 약속 시간을 문자로 알려 주세요. / 카톡으로 알려 주세요.

Is the word order fixed? Could I say 메시지로 약속 시간을 알려 주세요?

Word order is flexible. Both are natural:

• 약속 시간을 메시지로 알려 주세요.
• 메시지로 약속 시간을 알려 주세요. Putting 약속 시간을 first lightly emphasizes the item; putting 메시지로 first highlights the method.

Where is “me” in this sentence? Should I add 저한테/저에게?

Korean often omits obvious participants. Here, the recipient “me” is understood.

• Adding it is fine if you want to be explicit: 저한테(=to me) 메시지로 알려 주세요 or 저에게 메시지로 알려 주세요.
• 한테 is more conversational; 에게 is more formal/written.

Is it 알려 주세요 or 알려주세요? Which spacing is correct?

Both are widely seen, but standard orthography prefers spacing the auxiliary verb: 알려 주세요 (main verb + auxiliary 주다). In careful writing, use the space. In casual texting, 알려주세요 is common and acceptable.

Why is there a space in 약속 시간? I often see 약속시간.

In standard spacing, a modifier noun plus head noun is written with a space: 약속 시간 (“appointment time”). Closed-up 약속시간 appears informally, but formal writing favors the spaced form.

Difference among 알려 주세요, 말해 주세요, and 가르쳐 주세요?

• 알려 주세요: “please let me know/inform me”—neutral and very common for facts like times, addresses, etc.
• 말해 주세요: “please tell me”—focus on saying it; also fine here.
• 가르쳐 주세요: literally “please teach me,” but in colloquial Korean it often means “tell me (the info).” Slightly more old-fashioned or learnerish in some contexts but still common.

Why 알려 and not 알아? What’s the difference between 알리다 and 알다?

• 알리다 = to inform/let someone know → 알려 주세요 asks the other person to provide information.
• 알다 = to know/understand → 알아 주세요 means “please understand/please be aware,” which is a different request.

Can I use the topic marker: 약속 시간은 메시지로 알려 주세요?

Yes. 약속 시간은 makes “the appointment time” the topic, often with a contrastive feel: “As for the appointment time, please let me know by message (as opposed to something else).” Use -은/는 when contrasting or setting a topic.

How can I adjust politeness or formality?

• Casual: 약속 시간 문자로 알려 줘.
• Polite neutral: 약속 시간을 메시지로 알려 주세요.
• Softer/indirect: 약속 시간을 메시지로 알려 주시겠어요? / 알려 주실 수 있나요?
• Formal/business: 약속 시간을 메시지로 알려 주시기 바랍니다. / 알려 주십시오. Note the spelling: 주십시오 (not “주십시요”).

What’s the nuance difference between 알려 주세요 and 보내 주세요 here?

• 알려 주세요 focuses on providing the information (any method, but you’ve specified “by message”).
• 보내 주세요 focuses on sending something. With this content, you can say 약속 시간을 메시지로 보내 주세요 (“send me the appointment time by message”), which is also natural.

Should I end this with a period or a question mark?

Grammatically it’s an imperative request, so a period is standard: …알려 주세요. In casual messages, a question mark is often used to soften the tone: …알려 주세요? Both are common in texting; in formal writing, use a period.

When do I use 드리다 instead of 주다, like 알려 드릴게요?

Use 드리다 when the subject is you (or your in-group) doing something for a higher-status recipient—it’s the humble form of 주다.

• Asking someone else: 알려 주세요/주십시오 (you want them to do it).
• Telling someone you will do it: 제가 약속 시간을 문자로 알려 드릴게요 (“I’ll let you know the time by text”).

Is 시간 the best word? What about 시각 or other options?

• 시간 can mean “time” (both point in time and duration); in everyday speech it’s used for specific times too.
• 시각 means a specific clock time and is more formal/literary. You could say 약속 시각을…, but it’s uncommon in casual speech.
• If you want the date: 약속 날짜를…; the place: 약속 장소를…; all details: 약속 내용을… or 약속 관련 정보를….

Could I just say 약속을 메시지로 알려 주세요?

You can, but it changes the scope:

• 약속 시간을… asks specifically for the time.
• 약속을… sounds like “let me know the appointment (details)”—broader, possibly including time, place, etc.

Any common mistakes to avoid with this sentence?

• Using the wrong particle for means: avoid 메시지에/으로서 here; use 메시지로.
• Mixing up verbs: avoid 알아 주세요 when you mean “let me know.”
• Misspelling the formal request: 주십시오 (not “주십시요”).
• Over-marking recipients with honorific to self: don’t say 저께; use 저에게/저한테 if needed.
