Cleaning Up a Common Room | Learn Korean in English

Sentence explanations

1. 우리는 공용실을 한동안 사용했어.

   We used the common room for a while.

   우리는

   we

   공용실을

   common room

   한동안

   for a while

   사용했어

   used

   More detail

   우리는 means “we” here. 우리 is the base pronoun, and 는 marks it as the topic. Korean does not mark person on the verb, so 사용했어 does not itself repeat who “we” is. 우리 can also mean “our” before a noun; its role is determined by the surrounding structure. 공용실을 refers to “the common room” in this sentence. 공용실 is the noun “common room,” and 을 is the object particle, used here because the noun ends in a consonant. A useful pattern is 명사 + 을/를 for a direct object; 를 is used after a vowel-ending noun. 한동안 means “for a while.” It is a time expression describing a limited period, rather than a precise measured duration. Example: 한동안 쉬었어 means “I rested for a while.” 사용했어 means “used” here. Its base form is 사용하다, “to use.” This is the informal plain past form: the past marker and ending in 사용하였어 contract to 사용했어. Korean verb endings do not change for the subject’s person, so the same past form can occur with different subjects when the context identifies them. 사용해 is the corresponding informal present or general form, while 사용했어 places the action in the past. Together, 우리는 sets “we” as the topic, 공용실을 marks “the common room” as the object, 한동안 gives the duration, and 사용했어 states the completed past action. The whole utterance therefore means: “We used the common room for a while.”

2. 나가기 전에 정리하자.

   Let's clean it up before we head out.

   나가기 전에

   before heading out

   정리하자

   let’s tidy up

   More detail

   나가기 전에: 나가다 means “to go out” or “to leave.” Its form 나가기 uses -기 to turn the verb into an event or action; 전에 means “before.” Together, 나가기 전에 means “before leaving” or “before we head out.” The subject of 나가다 is understood from the situation rather than marked in this phrase. 정리하자: 정리하다 means “to tidy up,” “organize,” or “clean up.” Here it appears as 정리하자, formed with the informal propositive ending -자, which suggests an action shared by the speaker and listener: “let’s tidy up.” This ending is different from a plain statement such as 정리해 (“tidy up” or “you tidy up,” depending on context) because -자 explicitly presents the action as a joint proposal. The pattern 동사-기 전에 is reusable for “before doing …”: for example, 먹기 전에 손을 씻자 means “Let’s wash our hands before eating.” As a whole, 나가기 전에 정리하자. means “Let’s clean it up before we head out.” In the bounded context, the cleanup concerns the common room and its used items, including putting the chairs back, but the Korean sentence itself leaves the object of 정리하다 implicit.

3. 의자들을 원래 있던 곳에 다시 놓을게.

   I'll put the chairs back where they were.

   의자들을

   the chairs

   원래 있던 곳

   the place they were originally in

   다시

   back; again

   놓을게

   I’ll put them

   More detail

   의자들을 means “the chairs” here. 의자 is “chair,” -들 marks a plural group, and -을 marks that group as the object of the action. 의자를 can refer to one or more chairs when the context does not state plurality; here, the translation and context identify multiple chairs. 원래 있던 곳 means “the place where they originally were.” 원래 means “originally” or “as before.” 있다 means “to exist” or “to be located,” and 있던 modifies 곳 to describe a location that held previously. 곳 means “place.” Korean places the describing clause before the noun: [원래 있던] 곳 = “the place [they were originally in].” The chairs are understood as the located subject of 있던 from the fixed translation and sentence meaning. 다시 means “again” or “back” here and indicates returning the chairs to their earlier location or arrangement. For example, 다시 시작해요 means “Let’s start again.” 놓을게 comes from 놓다, “to put or place,” plus -(으)ㄹ게요, an ending used when the speaker undertakes or offers to do something. The stem 놓- ends in a consonant, so this ending has the form 놓을게요; after a vowel-ending stem, the corresponding form uses -ㄹ게요, as in 갈게요 (“I’ll go”). The observed 놓을게 is the informal, non-polite form without 요; 놓을게요 is the polite form. This ending presents the action as the speaker’s commitment or offer rather than merely stating a neutral future. For example, 제가 문을 닫을게요 means “I’ll close the door.” Together, 의자들을 identifies the chairs to be moved, 원래 있던 곳 identifies their original location, 다시 adds the idea of returning them, and 놓을게 makes this the speaker’s undertaking: “I’ll put the chairs back where they were.”

4. 탁자 위 쓰레기는 내가 치울게.

   I'll clear the trash from the tables.

   탁자

   table

   위

   top; above

   쓰레기

   trash

   내가

   I; subject form

   치울게

   I’ll clear it

   More detail

   탁자: This is the noun “table.” Its observed form is singular; Korean nouns generally do not change form for singular versus plural, so number is often understood from context. Example: 탁자 옆에 의자가 있어요. — “There is a chair beside the table.” 위: Here it means “on top of” or “above.” In 탁자 위, it follows the noun and forms a location phrase; with the following noun, 탁자 위 쓰레기 means “trash on the table.” Example: 책이 탁자 위에 있어요. — “The book is on the table.” 쓰레기: This noun means “trash” or “garbage.” Korean nouns do not normally require a separate plural ending here, so the form can refer to trash as a mass or to items understood from context. In this sentence, it is the thing being cleared. 내가: This is 나 (“I”) plus the subject marker 가. 나 is the ordinary first-person singular pronoun in less formal speech, and 내가 marks the speaker as the subject of 치울게. The subject marker identifies who performs the action; it does not by itself mean “alone” or add a numeric count. 치울게: The base verb is 치우다, “to clear away, put away, or tidy up.” Here it is inflected as 치울게, using -ㄹ게 after the verb stem 치우-. This ending presents the speaker’s intention or commitment to do the action, often with the listener in mind: “I’ll clear it.” It is not simply a neutral future tense. Example: 제가 정리할게요. — “I’ll organize it.” The topic-marked phrase 탁자 위 쓰레기는 means “as for the trash on the table.” 는 marks that whole noun phrase as the topic, while 내가 identifies the person who will act. Korean commonly places the object before the verb, so 쓰레기는 ... 치울게 has the structure “the trash ... I’ll clear.” Together, the utterance means: “I’ll clear the trash from/on the table.” The -ㄹ게 ending makes this sound like the speaker is volunteering or committing to handle it, rather than merely predicting a future action.

5. 불도 끌까?

   Should we turn off the lights too?

   불

   the lights

   도

   too; also

   끌까?

   shall we turn off?

   More detail

   불 means “the lights” here, as established by the fixed translation. The word can also mean “fire” in other contexts, and the verb 끄다 is compatible with both lights and fire; the translation identifies the intended sense here. 도 is an additive particle meaning “too” or “also.” It attaches directly to the noun or noun phrase being added. Thus 불도 means “the lights too.” 끌까? comes from 끄다, “to turn off” or “extinguish,” plus the sentence ending -ㄹ까?. The form 끌까? proposes an action to the listener: “shall we turn off…?” or “should we turn off…?” The base 끄다 changes to 끌까 before this ending; this is not a separate verb. Compare 불을 꺼. in the supplied context, where 꺼 is the plain command form “turn off.” As a reusable pattern, N도 V-(으)ㄹ까? can mean “Shall we V N too?” when the speaker proposes adding N to an action. For example, 커피도 마실까? means “Shall we drink coffee too?” This is a new example, not a statement about the supplied conversation. Together, 불도 marks the lights as an additional object, and 끌까? asks whether the speaker and listener should turn them off. The whole utterance therefore means “Should we turn off the lights too?” It is a concise, conversational proposal.

6. 불을 꺼.

   Turn off the lights.

   불

   lights

   꺼

   turn off

   More detail

   불 means “light” here, specifically the light(s) being turned off. In other contexts, the same noun can mean “fire”; the fixed translation establishes the intended meaning here. 불을 contains the object particle 을, which marks 불 as the thing affected by the action. 꺼 is the informal command form of 끄다, “to turn off.” The verb stem 끄- combines with -어, and the vowels contract to produce 꺼. This casual command is used when an informal command is appropriate; a polite request form is 꺼요. Together, 불을 꺼 means “Turn off the lights.” The subject is not stated because the utterance directly commands the listener. A reusable pattern is [object]을/를 꺼 for telling someone to turn off a relevant object, with the object particle selected according to the object’s form.

7. 문을 잠그기 전에 창문을 닫아.

   Close the windows before we lock up.

   문

   door

   잠그기 전에

   before locking up

   창문

   window(s)

   닫아

   close

   More detail

   문 means “door.” The form is a noun and does not itself mark singular versus plural. A reusable example is 문을 열어. — “Open the door.” Here, 문을 is the object phrase; 을 marks the object. 잠그기 전에 expresses “before locking up.” It is built from 잠그다 (“to lock”), -기 (which turns the verb into an activity or event), and 전에 (“before”). The form 잠그기 is not a separate verb: it is the nominalized form of 잠그다. A reusable pattern is V-기 전에 — “before V-ing”: 자기 전에 이를 닦아. — “Brush your teeth before going to bed.” The subject of 잠그다 is not stated in the Korean sentence; the fixed translation supplies the intended “we.” 창문 means “window” or “windows.” Korean commonly leaves number unmarked, so this form can refer to one or more windows; the fixed translation selects the plural meaning here. As a noun, it can take object marking: 창문을 means “the window(s)” as the object. 닫아 means “close.” It is the informal plain imperative form of 닫다 (“to close”), used here as a direct instruction. The final -아 ending is also used in casual speech for this kind of command. For example, 문을 닫아. means “Close the door.” Together, 창문을 닫아 means “Close the windows,” while 문을 잠그기 전에 places that instruction before the event of locking up: “before we lock up.” The complete utterance is therefore “Close the windows before we lock up.”

8. 방이 다음 사람들이 쓸 준비가 된 것 같아.

   The room looks ready for the next group.

   방

   room

   다음

   next

   사람들이

   people; group

   쓸

   will use; use

   준비가 된

   ready

   것 같아

   seems; looks like

   More detail

   방 means “room” here. It is a noun and can be reused directly before particles or other phrases: 방이 means “the room is …,” while 방을 means “the room” as an object. Example: 방이 넓어요. — “The room is spacious.” 다음 means “next” or “following.” Before a noun, it identifies what comes later in an order or sequence: 다음 사람 means “the next person,” and 다음 그룹 means “the next group.” In this sentence, it modifies 사람들이, giving the intended meaning “the next people/group.” 사람들이 means “people” in this sentence. The noun 사람 means “person,” and 들 is a plural marker, so 사람들 means “people.” 이 is the subject marker attached to the plural noun. Korean may omit 들 when plurality is clear from context, but it is present here. Example: 사람들이 와요. — “People are coming.” 쓸 is the attributive form of 쓰다, “to use.” In this form, 쓸 means “that [someone] will use” or “for [someone] to use,” and it comes before the noun 준비. This is not the verb 쓰다 by itself; it is the form that modifies a following noun. Example: 제가 쓸 의자예요. — “It is a chair that I will use.” 준비가 된 means “ready” or “prepared.” 준비 means “preparation,” 가 marks it as the subject of 되다, and 된 is the form of 되다, “become,” that modifies a following noun or the noun-like expression 것. The completed form 된 presents the state as already achieved: 준비가 되다 means “become/be ready,” and 준비가 된 means “ready/prepared.” Example: 출발할 준비가 됐어요. — “We are ready to leave.” 것 같아 means “seems” or “looks like.” 것 is a noun meaning “thing,” and 같아 is the informal-present form of 같다, “be similar/like”; together, 것 같다 expresses an impression or inference. After a clause, it means that the situation appears to be so rather than stating it as certain. Example: 비가 오는 것 같아. — “It looks like it is raining.” The structure 쓸 준비가 된 means “ready for [someone] to use”: 쓸 describes the use, and 준비가 된 describes the room’s resulting state. Adding 것 같아 turns the whole description into an impression. Thus 방이 다음 사람들이 쓸 준비가 된 것 같아 means “The room looks ready for the next group to use,” matching the fixed translation. The informal ending 아 suits a casual conversation.

9. 그럼 문을 잠그고 나가자.

   Then we can lock the door and leave.

   그럼

   then

   문

   door

   잠그고

   lock and

   나가자

   let’s leave

   More detail

   그럼 is a shortened form of 그러면, meaning “then” or “in that case.” It introduces a next action connected to the situation already established. 문 means “door.” In this sentence, it appears as 문을: the particle -을 marks 문 as the object of the locking action. The noun is therefore not standing without an object marker here. 잠그고 comes from 잠그다, “to lock.” The ending -고 connects this action to the following one, so 잠그고 나가자 means “lock it and let’s leave.” The object being locked is 문을, and the subject is understood across the connected actions. 나가자 comes from 나가다, “to go out” or “to leave.” The ending -자 proposes a shared action and is commonly translated as “let’s.” For example, 먹자 means “Let’s eat.” Together, 문을 잠그고 나가자 means “Let’s lock the door and leave.” With 그럼 at the beginning, the whole utterance means “Then we can lock the door and leave.” The English “we can” conveys the proposed joint action; the Korean -자 directly presents it as a suggestion.
