알려주다

The Korean verb 알려주다 (allyeojuda) is a foundational compound verb that every learner must master to communicate effectively. At its core, it combines two distinct verbs: 알다 (alda), meaning 'to know,' and 주다 (juda), which means 'to give.' When fused together, they create a meaning that literally translates to 'giving the state of knowing' to someone else. In English, we most commonly translate this as 'to let someone know,' 'to inform,' 'to notify,' or 'to tell.' It is the go-to word when you are sharing information, facts, or news that the other person doesn't already possess.

The Nuance of 'Giving'

In Korean grammar, the auxiliary verb -어/아 주다 is added to other verbs to indicate that the action is being performed as a favor or for the benefit of someone else. Therefore, 알려주다 carries a subtle undertone of helpfulness. You aren't just stating a fact; you are providing the service of informing the listener.

People use 알려주다 in a vast array of contexts, from the mundane to the formal. You would use it when asking for someone's phone number, inquiring about a bus schedule, or requesting a status update on a project at work. It is distinct from 가르치다 (gareuchida), which means 'to teach' or 'to instruct.' While learners often confuse the two, 알려주다 is used for simple facts or information, whereas 가르치다 implies a transfer of skill or academic knowledge. For example, you 'teach' (가르치다) Korean, but you 'let someone know' (알려주다) the time of the class.

Understanding the frequency of this word is vital. In a typical day in Seoul, you might hear this word dozens of times. A subway announcement might 'inform' you of the next stop; a waiter might 'let you know' that a dish is sold out; a friend might 'tell you' where they bought their new shoes. It bridges the gap between casual conversation and professional correspondence, making it one of the most versatile tools in your Korean vocabulary kit. It functions as both a request for information ('Please tell me') and a statement of intent ('I will let you know').

Social Dynamics

Because Korean culture places heavy emphasis on social hierarchy and politeness, the way you use 알려주다 changes based on who you are talking to. Using 알려줘 with a boss would be a major faux pas, while using 알려주십시오 with a close younger sibling might sound strangely robotic or sarcastic. Mastering the conjugation of this verb is a gateway to mastering Korean social etiquette.

Using 알려주다 correctly requires an understanding of basic Korean sentence structure and particle usage. The person receiving the information is marked with the dative particles 에게 (ege), 한테 (hante), or the honorific 께 (kke). The information being shared is typically the object of the sentence, marked with 을/를 (eul/reul). However, often the 'information' is a clause, such as 'when the bus arrives' or 'where the bathroom is,' which requires specific grammatical connectors like -는지.

Basic Structure

[Subject] + [Recipient] + [Information] + 알려주다. For example: '저는 친구에게 비밀을 알려주었어요' (I told my friend the secret).

One of the most common ways to use this verb is in the imperative form to ask for information. In casual settings, you say 알려줘 (allyeojwo). In polite daily life, 알려주세요 (allyeojuseyo). In very formal situations or when addressing a large audience, 알려드립니다 (allyeodeurimnida) is preferred. Note that 알려드립니다 is the humble form, literally 'I humbly give you the knowing,' and is ubiquitous in public announcements and emails.

The verb also pairs beautifully with various intentions and tenses. To express a promise to inform someone in the future, you use the -(으)ㄹ게요 ending: 알려줄게요 (allyeojulgeyo). To express a completed action of informing, use the past tense: 알려줬어요 (allyeojwosseoyo). It's also frequently used with -달라고 하다 (to ask someone to do something) in indirect speech: '그녀는 나에게 시간을 알려달라고 했어요' (She asked me to tell her the time).

Complex Clauses

When the information is a question, use -는지/은지/ㄴ지. Example: '어디에 있는지 알려주세요' (Please let me know where it is). This is a highly natural way to speak Korean.

Finally, consider the use of 알려주다 in the negative. If you cannot share information, you might say 알려줄 수 없어요 (I can't let you know) or 알려주지 마세요 (Don't let [them] know). The flexibility of this verb across different grammatical patterns makes it an essential building block for constructing both simple and complex ideas in Korean.

To truly master 알려주다, you need to recognize it in its natural habitats. This isn't just a word found in textbooks; it is the lifeblood of communication in South Korea. From the moment you step off a plane at Incheon International Airport to the moment you order delivery on an app, 알려주다 is everywhere. It is the polite lubricant of social interaction, ensuring that everyone is on the same page.

Public Announcements

In subways, malls, and airports, you will hear: '안내 말씀 알려드립니다' (We are giving you an announcement). Here, the humble version 알려드립니다 is used to show respect to the public.

In the digital world, 알려주다 is equally prevalent. When you sign up for a service, you might see a button that says '알림 설정' (Notification settings), derived from the same root. Apps will send you '알림' (notifications) to '알려주다' (inform) you of new messages or sales. If you are watching a K-drama, you'll often hear a character say, '나중에 알려줘' (Tell me later) or '누구한테도 알려주지 마' (Don't tell anyone). It is the standard way to handle secrets, news, and plans in dialogue.

In business settings, 알려주다 is the professional standard. Emails often begin with phrases like '변경 사항을 알려드리고자 합니다' (I would like to inform you of the changes). It sounds much more professional and softer than using direct verbs like 말하다 (to say) or 쓰다 (to write). It frames the communication as a helpful exchange rather than a one-way command. If you are working in Korea, you will likely use 알려드리다 multiple times a day in your correspondence.

Customer Service

When you call a service center, the agent will say, '성함을 알려주시겠습니까?' (Could you please let me know your name?). It is the polite way to ask for personal details without being intrusive.

Even in romantic contexts, the word appears. A partner might say, '네 마음을 알려줘' (Let me know your heart/feelings). It’s a versatile word that spans the entire emotional and professional spectrum of human life in Korea. By paying attention to these contexts, you'll start to see how 알려주다 acts as a vital connective tissue in Korean society.

For English speakers, the most frequent mistake when using 알려주다 is confusing it with 가르치다 (gareuchida). In English, we often use the word 'teach' and 'tell' interchangeably in certain contexts. For example, 'Can you teach me the way to the station?' sounds okay in English, but in Korean, using 가르치다 in this context implies you want a formal lesson on navigation. Instead, you should use 알려주다 because you are simply asking for information (the route).

Mistake 1: The 'Teach' vs. 'Tell' Confusion

Incorrect: 전화번호를 가르쳐주세요. (Though common in casual speech, it technically means 'Teach me your phone number.')
Correct: 전화번호를 알려주세요. (Let me know your phone number.)

Another common error involves the honorific forms. Beginners often forget that 알려주다 is a compound of 알리다 and 주다. When speaking to someone higher in status, you must change 주다 to 드리다. Saying '사장님, 제가 알려줄게요' (CEO, I'll let you know) is incredibly rude because -줄게요 is casual/polite but not humble. The correct form is 알려드릴게요. Conversely, you should never use 알려드리다 when talking about yourself giving information to a child or a close friend, as it would sound bizarrely formal.

The third mistake is related to particles. Many learners use the object particle 를/을 for the person being informed, influenced by the English 'inform someone.' In Korean, the person is the recipient of the 'giving' action, so you must use 에게 or 한테. Saying '친구를 알려줬어요' would mean 'I informed [someone] about my friend' or, weirdly, 'I gave my friend away,' rather than 'I told my friend.'

Mistake 2: Wrong Recipient Particle

Incorrect: 동생을 길을 알려줬어요.
Correct: 동생에게 길을 알려줬어요.

Finally, some learners use 말해주다 (to tell/speak to) when 알려주다 is more appropriate. While 말해주다 focuses on the act of speaking, 알려주다 focuses on the transfer of information. If you want to know a specific fact, 알려주다 is almost always the better choice. Avoiding these pitfalls will make your Korean sound significantly more natural and native-like.

While 알려주다 is the most versatile term, Korean offers several synonyms and alternatives that are more appropriate in specific contexts. Understanding these differences will help you reach a higher level of fluency. The nuances often depend on the level of formality, the medium of communication (written vs. spoken), and the nature of the information being shared.

알려주다 vs. 가르쳐주다

As mentioned, 알려주다 is for facts/info, while 가르쳐주다 is for skills/knowledge. However, in casual spoken Korean, people often use 가르쳐주다 for things like phone numbers or directions. It's technically less precise but very common.

For more formal or official contexts, you will encounter 공지하다 (gongjihada) and 통보하다 (tongbohada). 공지하다 is used for public notices or announcements made to a group (like a school notice or a company-wide email). 통보하다 is more serious and often used for official notifications, like a legal notice or a formal result of an exam. It can sometimes sound a bit cold or authoritative.

Another interesting alternative is 귀띔하다 (gwittwimhada), which means 'to give a hint' or 'to tip someone off' privately. This is much more specific than 알려주다 and implies a level of secrecy or inside information. If you are reporting to a superior, you might use 보고하다 (bogohada), which specifically means 'to report' work progress or findings.

Comparison Table

• 알려주다: General, helpful, 'let know'.
• 알리다: To inform/notify (more formal, often one-way).
• 말해주다: To tell (focus on the act of talking).
• 안내하다: To guide/direct (focus on showing the way).

Choosing the right word shows that you understand the social context and the specific type of information being shared. While you can almost never go wrong with 알려주다, using these alternatives will make your Korean sound more precise and sophisticated. For instance, saying '결과를 통보받았습니다' (I was notified of the results) sounds much more 'official' than '결과를 알려줬어요' (They told me the results).
