Put the describing clause before its noun

책을 읽는 사람 is ‘the person who reads a book’ or ‘the person reading a book.’ Korean puts the description before 사람, the noun it describes. There is no separate word matching English ‘who’ in this phrase; the ending on 읽는 connects the action to the person.

That order can feel unfamiliar at first, especially when the description is long. Finding the final noun gives you an anchor. You can then work back through the words before it to see what happened, who was involved, and whether the action is current, completed, or expected. The examples here keep one noun in place while changing its description.

Compare one action across three noun modifiers

Compare 책을 읽는 사람, 책을 읽은 사람, and 책을 읽을 사람. The noun 사람 stays the same. 읽는 presents a current or characteristic action, 읽은 presents a completed reading, and 읽을 points toward someone who will or is to read. Context tells you which English wording sounds most natural.

The noun does not always represent the person doing the action. In 제가 만난 선생님, 제가 is the person who did the meeting, and 선생님 is the teacher I met. Korean leaves that object position understood inside the description because the final noun supplies it. This is why reading the particles inside the clause matters.

Choose the form from predicate type and time

For action verbs, the examples use -는 for a current action, -(으)ㄴ for a completed action, and -(으)ㄹ for a prospective one. 먹는 음식, 먹은 음식, and 먹을 음식 show the same contrast with food. A vowel-final stem gives 만난 사람 or 만날 사람; a consonant-final stem gives 먹은 음식 or 먹을 음식.

Descriptive words often use -(으)ㄴ for a present quality: 작은 방 and 좋은 생각 mean a small room and a good idea. 있다 and 없다 are an important exception, giving 있는 and 없는. Words built with them also need attention: 맛있다 becomes 맛있는, and 재미있다 becomes 재미있는. 맛있는 음식 therefore uses -는, even though it describes a quality. Irregular stems and ㄹ-final stems need their own form checks.

Identify the intended person by the clause

어제 회의에서 발표한 사람 identifies someone through a completed event: presenting at yesterday’s meeting. 창가에 앉아 있는 분 identifies the same person through their current position by the window. 분 is a respectful noun for a person, so the answer also changes the tone of reference.

다음 주에 보고서를 쓸 사람 describes the person expected to write next week’s report. The reply says that is Jisu, rather than the presenter. 어제 and 다음 주 make the time contrast easy to follow. Each description comes before the person it identifies, even when English places a ‘who’ clause afterward.

Recover the missing role inside the clause

제가 만난 선생님 and 저를 만난 선생님 may look very similar. In the first, 제가 marks me as the subject: ‘the teacher I met.’ In the second, 저를 marks me as the object: ‘the teacher who met me.’ The ending 만난 is unchanged, but the particle changes the relationship.

The main sentence has its own time as well. 책을 읽은 사람을 만날 거예요 means you will meet the person who read the book: the reading is completed, while the meeting is still ahead. A noun modifier describes its noun; it does not automatically set the time of every action in the sentence.

Correct likely misunderstandings

The description belongs to the noun immediately after it. 맛있는 사람이 먹어요 describes a ‘tasty person’ as the subject, which is not what you want when talking about tasty food. 사람이 맛있는 음식을 먹어요 puts 맛있는 beside 음식 and says the person eats delicious food.

When translating ‘the teacher I met,’ 제가 만난 선생님 is enough. Adding 선생님을 inside that same description repeats the role already filled by the final 선생님. In a longer phrase such as 다음 달에 공개될 오래된 지도, 지도 is the noun, and both 공개될 and 오래된 describe it: an old map that will be released next month.
