Korean Imperative Forms: Commands and Requests Guide

Learning Korean means you'll eventually need to tell someone to do something, whether that's asking a friend to pass the kimchi or politely requesting directions from a stranger. Korean imperative forms handle all of this, and they're actually pretty straightforward once you understand the basic patterns. The key is matching your command or request to the right politeness level, because Korean takes social hierarchy seriously. Let's break down exactly how to conjugate verbs into commands and requests without sounding rude or awkward.

What is an imperative form in Korean?

An imperative in Korean works just like in English: it's how you give commands, make requests, or offer suggestions. The difference is that Korean has multiple imperative forms depending on who you're talking to and how polite you need to be.

In English, we mostly use the base verb: "Go!", "Eat!", "Please help me." Korean requires you to conjugate the verb with specific endings that signal both the imperative mood and the appropriate politeness level. You can't just throw out a verb stem and hope for the best.

The Korean imperative system divides into three main politeness levels: informal (for close friends and younger people), polite (for everyday situations with strangers or acquaintances), and formal (for very respectful situations). Each level has its own conjugation pattern.

Here's the thing: Korean learners often get confused because the same request can sound completely different depending on context. Telling your younger sibling to eat versus asking your boss to eat requires totally different verb endings. Get it wrong, and you might come across as either too casual or weirdly stiff.

Polite imperative forms with (으)세요

The polite imperative ending (으)세요 is your go-to form for most everyday situations. You'll use this with strangers, service workers, teachers, or anyone you want to show basic respect toward.

The conjugation rule is simple: look at the verb stem. If the stem ends in a vowel, add 세요. If it ends in a consonant, add 으세요.

Let's use 가다 (to go) as an example. The verb stem is 가, which ends in a vowel. So you get 가세요 (please go).

For 먹다 (to eat), the stem is 먹, ending in a consonant. Add 으세요 to get 먹으세요 (please eat).

More examples:

This form works for both commands and requests. The context and tone determine whether you're commanding or politely asking. In a restaurant, 주세요 (please give) sounds like a request. A teacher saying 앉으세요 to students is more of a command, even though the ending is polite.

The 주세요 form deserves special mention because you'll hear it constantly. It comes from 주다 (to give) and functions as "please give me" or "I'd like." 물 주세요 means "Water, please." 도와주세요 means "Please help me."

Informal imperative with 아/어(요)

When talking to close friends, younger siblings, or people clearly junior to you, the informal imperative uses 아/어 or 아요/어요 endings. The 요 makes it slightly more polite while still casual.

The conjugation depends on the last vowel in the verb stem. If the stem has ㅏ or ㅗ as the final vowel, use 아. For all other vowels, use 어.

Take 가다 again. The stem 가 has ㅏ, so you add 아 to get 가 (just 가, because 가 + 아 contracts). Add 요 for 가요 (go, casual-polite).

For 먹다, the stem 먹 would become 먹어 in the informal imperative (eat!). With 요, it's 먹어요.

More examples:

The version without 요 sounds very casual and direct. You'd only use it with people you're super close to. The 요 version keeps things friendly but still respectful enough for most casual relationships.

This form also works for suggestions. 같이 가요 means "Let's go together" when said with the right intonation. Context really matters here.

Formal imperative with 아/어라

The 아/어라 ending creates a strong, direct command. You'll mostly see this in writing, military contexts, or when someone with authority is giving orders. Parents sometimes use it with young children.

The conjugation follows the same vowel rules as the informal imperative. If the stem has ㅏ or ㅗ, use 아라. Otherwise, use 어라.

Examples:

This form sounds pretty harsh in spoken conversation. You'd hear it in movies when a boss is yelling at subordinates or in historical dramas. Most Korean learners won't need to use this much in real life, but you should recognize it when you encounter it.

Negative imperatives with 지 마세요

Telling someone NOT to do something requires the negative imperative. The polite form uses 지 마세요 attached to the verb stem.

The pattern is super consistent: verb stem + 지 마세요. No vowel or consonant variations to worry about.

Examples:

For informal situations, drop the 세요 and just use 지 마 or 지 마요. 가지 마 means "don't go" to a friend. 가지 마요 adds a touch more politeness while staying casual.

The negative imperative is actually easier than the positive forms because the conjugation pattern stays the same regardless of the verb stem ending. Pretty convenient.

Understanding verb stems and conjugation basics

To conjugate any Korean verb into an imperative form, you need to identify the verb stem first. Korean verbs in dictionary form always end in 다. Remove the 다 and you've got your stem.

가다 → stem is 가 먹다 → stem is 먹 공부하다 (to study) → stem is 공부하

Once you have the stem, check whether it ends in a vowel or consonant. This determines which ending variant you'll use for most imperative forms.

Vowel-ending stems are easier because they take the shorter endings. Consonant-ending stems need the extra 으 syllable to make pronunciation smooth.

The vowel harmony rule (ㅏ/ㅗ versus everything else) applies to several Korean grammar patterns, not just imperatives. Learning this once helps with multiple verb forms.

Irregular verbs in imperative forms

Korean has irregular verbs that don't follow the standard conjugation patterns. The most common irregular types affect imperative forms.

ㄹ irregular verbs drop the ㄹ when you add certain endings. For example, 살다 (to live) becomes 사세요, not 살으세요. The ㄹ disappears before 으.

ㅂ irregular verbs change ㅂ to 우 or 오. 돕다 (to help) becomes 도우세요 instead of 돕으세요.

ㄷ irregular verbs change ㄷ to ㄹ. 듣다 (to listen) becomes 들으세요.

으 irregular verbs drop the 으 from the stem. 쓰다 (to use) has the stem 쓰, but conjugates like a vowel-ending stem: 쓰세요.

These irregular patterns take practice to internalize. The good news is that the most common verbs follow regular patterns, so you can communicate effectively while gradually learning the exceptions.

Politeness levels and when to use each form

Korean society runs on hierarchy and respect, which means choosing the right imperative form matters a lot. Using an informal command with someone older or higher status can seriously offend them.

The (으)세요 form is your safe default. Use it with anyone you don't know well, anyone older, service staff, colleagues, teachers, and most social situations. You can't really go wrong with this level of politeness.

The informal 아/어(요) works with close friends your age or younger, siblings, and people who've explicitly told you to speak casually. Even then, adding the 요 shows you still care about being polite. Dropping the 요 completely should only happen with very close relationships.

The 아/어라 form is risky. Unless you're in a position of clear authority (parent to young child, military superior to subordinate), avoid it. It sounds aggressive and rude in most contexts.

For negative imperatives, 지 마세요 works in polite situations, while 지 마 or 지 마요 fits casual contexts with friends.

When in doubt, go more polite. Koreans will often tell you if you can speak more casually, but starting too informal creates a bad impression that's hard to fix.

Making requests versus giving commands

The same imperative sentence can function as either a command or a request depending on context, tone, and your relationship with the listener.

In a restaurant, 물 주세요 (water, please) is clearly a request. You're asking the server to bring you water. The polite ending and service context make it a request.

A boss telling an employee 이거 해 주세요 (please do this) sounds like a command disguised as a request. The politeness is there, but the power dynamic makes it an order.

Adding 주세요 (please give/do) to verb stems softens commands into requests. 도와주세요 (please help me) sounds much more like asking for help than commanding it.

Your tone matters too. The same words said with a smile versus barked sharply change the entire meaning. Korean relies heavily on context clues.

For true requests where you're genuinely asking rather than telling, you might also use question forms like 갈 수 있어요? (can you go?) instead of imperative forms. This makes it even clearer that the other person has a choice.

Common imperative sentence examples

Let's look at practical examples you'll actually use when learning Korean.

Commands and requests you'll hear daily:

Casual imperatives with friends:

Negative imperatives:

These examples show how imperative forms appear in real conversations. You'll encounter them constantly in Korean media, so recognizing the patterns helps your comprehension even before you start producing them yourself.

Practice tips for mastering Korean imperatives

Start by memorizing the most common verbs in their imperative forms. 가다, 오다, 먹다, 하다, 보다, 주다 appear everywhere, so drilling these first gives you immediate practical value.

Pay attention to politeness levels in Korean shows and videos. Notice when characters use 세요 versus 아/어 versus 아/어라. The social dynamics usually make it obvious why they chose that level.

Practice conjugating verbs yourself. Take a verb, identify the stem, check the final vowel or consonant, then apply the appropriate ending. Do this enough times and the patterns become automatic.

Listen for 마세요 in negative commands. Korean media loves dramatic moments where someone yells 가지 마! (don't go!), so you'll hear plenty of examples.

Don't stress about irregular verbs initially. Learn the regular patterns first, then gradually add the common irregular verbs as you encounter them.

Commands for learning Korean effectively

Korean imperative forms follow logical patterns once you understand the vowel and consonant rules. The politeness level system seems complicated at first, but it reflects how Korean society actually works.

Focus on the (으)세요 form first. It covers 80% of situations you'll encounter as a learner. Once that feels natural, add the informal 아/어요 for casual conversations. The harsh 아/어라 form can wait until you're more advanced.

Negative imperatives with 지 마세요 are thankfully consistent and easy to learn. You'll use them often, so practice them alongside the positive forms.

The best way to internalize these patterns? Immersion. Watch Korean shows, listen to podcasts, read webtoons. You'll see imperative forms used naturally in context, which beats memorizing conjugation tables any day.

Learn it once. Understand it. Own it.
