After I eat, I brush my teeth.”

There are many people in Korea who brush their teeth during their lunch break, and the more cavity-prone people are, the more they take care of their dental health.

In this lesson, let’s practice grammar that can be used for this kind of talk.

Of course, this grammar can be used for more than just talking about brushing one’s teeth.

-후 means “after ~”.

Expressions using the 후(後).

When you want to express “after ~” in Korean, use -후.

The sentence “A after B”.

①TV를 봐요.
I watch TV.

그 후에 숙제를 할 거예요.
I do my homework after that.


③저는 TV를 에 숙제를 할 거예요.
I do my homework after watching TV.

Talk about order of action.

-후 represents an action or change “after something”.

How to use “- 후”.

후 is combined with a modifier verb.

Av + -ㄴ/은 후

오다 + -ㄴ/은 후 = 온 후
마시다 + -ㄴ/은 후 = 마신 후
운동하다 + -ㄴ/은 후 =  운동한 후

읽다 + -ㄴ/은 후 = 읽은 후
먹다 + -ㄴ/은 후 = 먹은 후
받다 + -ㄴ/은 후 = 받은 후

살다 + -ㄴ/은 후 = 산 후
듣다 + -ㄴ/은 후 = 들은 후

Just bring -후 after -ㄴ/은, which indicates the completion of an action.

No patchum in the stem

술을 마신 에 커피를 마시면 몸에 안 좋아요.
Drinking coffee after drinking alcohol is not good for you.
이 영화를 에 씻을 거예요.
I plan to take a bath after watching this movie.
근력운동을 에 우유를 마시면 근육에 좋아요.
Drinking milk after muscle training is good for your muscles.

If the verb stem does not have a patchum, use -ㄴ 후.

Have a patchum in the stem

수술을 받은 에는 안정이 필요합니다.
Rest is required after the surgery.
책을 읽은 에 소감을 써 봅시다.
Write down your thoughts after reading the book.
저는 항상 이를 닦은 에 가글을 해요.
I always gargle after brushing my teeth.

Use -은 후 when the stem of a word has a patchum.

Cases of irregular changes.

The usage is roughly the same as for -ㄴ/은.

서울에서 15년 에 인천으로 이사했어요.
After living in Seoul for 15 years, I moved to Incheon.
큰 소리를 들은 에는 이명이 발생하기 쉽습니다.

아침에 30분 정도 걸은에 줄넘기를 해요.
I walk for about 30 minutes in the morning and then jump rope.

The grammatical structure requires an understanding of ㄴ/은.

If you are not good at -ㄴ/은, you should also review so that you can make sentence patterns quickly.

It is not always necessary to use “-ㄴ/은 후”.

You can use nouns instead of verbs.

There are ways to do it without using verbs.

15분 에 도착할 겁니다.
We expect to arrive in approximately 15 minutes.
수업 에 친구랑 밥 먹으러 갈 거예요.
I go out to eat with friends after class.
대학 졸업 증권회사에 들어가고 싶어요.
I want to join a brokerage firm after college.

This is easy because you don’t bother to use the verb as a modifier.

You should practice -전 and -후 together.

Can be interchanged with “뒤” or “다음”.

or 다음 may be used instead of 후.

서울역에 모인  찰 타고 이동합니다.
After gathering at Seoul Station, we will get in the car and move on.
2시간 다시 시작합니다.
We will resume in two hours.
작업이 끝난 반드시 확인하세요.
Always check after the work is done.
14에서 2를 다음 3로 나눠요.
14 minus 2, then divide by 3.

The use of 뒤 or 다음 does not change the meaning of the sentence, but you should practice so that you can freely switch vocabulary at any time.

It would be a good idea to use ‘후’ to express your daily habits, etc.
