Doing Something Before Another: ~기 전에
Grammar Rule in 30 Seconds
Use ~기 전에 to say you do something before another action; just attach it to the verb stem.
- Attach ~기 전에 directly to the verb stem: 먹다 -> 먹기 전에.
- It works for both present and past tense main clauses.
- The subject of both clauses is usually the same person.
Overview
Ever sent a risky text and immediately regretted it? You definitely should have thought about the consequences before you hit that send button. That exact universal scenario is why we are looking at this specific Korean grammar rule today.
In the Korean language, expressing "before doing something" is an absolute survival skill. It helps you sequence your daily actions perfectly. It tells people exactly what to expect from you.
It keeps your timeline straight when telling a story. You will constantly use this pattern when ordering food on delivery apps. You will hear it in every single Netflix K-drama right before a massive plot twist happens.
You will text it to your best friends when you are running late for a meetup. It is truly everywhere.
The grammar pattern 기 전에 directly translates to "before doing" an action. It is built from two very simple, logical parts. First, we have the syllable 기.
This acts exactly like a magic wand in Korean grammar. It instantly turns a regular action verb into a noun. Second, we have the word 전에.
The word 전 전 literally means "before" or "prior" in Hanja, which are the Chinese characters that heavily influence Korean vocabulary. The particle 에 is a common time and location marker. In this context, it simply means "at" or "in".
So, when you put it all together literally, you are essentially saying "at the prior time of doing X". It sounds a bit formal and fancy when broken down like that, but in practical daily usage, it is incredibly simple. Think of it just like saying "prior to going" or "before eating" in English.
It attaches directly to the verb stem. There are absolutely no weird exceptions. There are no irregular verbs to memorize here.
It is honestly one of the friendliest and most consistent grammar rules you will ever learn in the Korean language.
How This Grammar Works
기 전에 to it, and then you say Action B. Action B is always the main event of your sentence.기 전에 part never, ever changes its tense. It stays exactly the same whether you are talking about something you did yesterday, something you are doing today, or something you plan to do next year. For example, if you want to say "Before I ate, I washed my hands," you absolutely do not make the verb "eat" into the past tense in Korean.기 전에 structure permanently locks the very first verb in its basic dictionary state. This brilliant feature saves you a lot of mental math and conjugation headaches!Formation Pattern
가다, which means "to go".
다 at the very end of the word. You are left with the basic verb stem 가.
기 전에 directly to that stem.
가기 전에, which perfectly translates to "before going".
먹다 (to eat) easily becomes 먹기 전에. 놀다 (to play) simply becomes 놀기 전에. 듣다 (to listen) naturally becomes 듣기 전에. Even the notoriously tricky irregular verbs behave perfectly here. There is literally zero weird conjugation to memorize for this specific rule. Furthermore, if you want to use a noun instead of a verb, the process is even easier. You just drop the 기 entirely. You just use Noun + 전에. For example, 수업 전에 simply means "before class". 회의 전에 means "before the meeting". 식사 전에 means "before the meal". You simply cannot get it wrong.
When To Use It
자기 전에 유튜브를 봐요 (I watch YouTube before sleeping).우리 만나기 전에 커피 마실까? (Should we drink coffee before we meet?). Use it professionally when giving polite instructions at work or school.퇴근하기 전에 이메일을 보내주세요 (Please send the email before getting off work). Use it digitally for modern activities like online shopping or ordering late-night snacks via Coupang Eats. 주문하기 전에 리뷰를 확인해요 (I always check the reviews before ordering).가기 전에 전화해 (Call me before you go - Casual).가기 전에 전화해 주세요 (Please call me before you go - Polite).Common Mistakes
갔기 전에 ✗. This is a massive red flag to native Korean speakers and sounds incredibly unnatural. Always use the basic verb stem: 가기 전에 ✓. Let the final verb at the end of the sentence handle all the past tense duties. The second frequent mistake is mistakenly adding 기 to a regular noun. If you want to say "before class", you absolutely do not say 수업기 전에 ✗. The word for class (수업) is already a noun. It does not need the magic wand 기 to transform it. Just say 수업 전에 ✓. Only use 기 when you are actively changing an action verb into a noun. Keep these two simple rules in mind, and you will sound incredibly natural and fluent.Contrast With Similar Patterns
-(으)ㄴ 후에. This grammar point means "after doing".기 전에 never changes its basic form, -(으)ㄴ 후에 forces you to carefully check the verb stem for consonants and vowels. You say 먹기 전에 (before eating) versus 먹은 후에 (after eating). Do you notice the slight difference in complexity?기 전에 with sequence connectors like 아/어/여서 (and then / so). The connector 아/어/여서 generally means you did Action A, and because of that, or immediately right after that, you did Action B. However, 기 전에 strictly sets a timeline of events.Quick FAQ
Does this grammar pattern work with adjectives or descriptive verbs?
Generally, no. Saying something like "before being pretty" sounds just as weird and unnatural in Korean as it does in English. Stick strictly to action verbs for this pattern.
Can I use this pattern with the copula 이다 (to be)?
It is grammatically possible to say 학생이기 전에 (before being a student), but it is more of an advanced, literary phrasing. You really won't use it much in your daily A2 level conversations.
Do I absolutely have to include the space between 기 and 전에?
Yes! Spacing is crucial in written Korean. 가기 전에 is 100% correct. Writing 가기전에 without a space is technically a typo, though you will definitely see it in fast, casual texting.
What if the subject of the two clauses is different?
You can absolutely have completely different subjects! For example, "Before Mom comes, I will clean." You say 엄마가 오기 전에 제가 청소할게요. Just make sure to use your subject markers clearly.
Is 전에 always explicitly required, or can I just say 기 전?
In very casual speech with friends, you can drop the 에 and just say 가기 전. It means "Before going." But adding 에 sounds much more complete, standard, and polite.

Avoid '기 전에' if the subjects are different; use a different structure.
