Sentence explanations

1. 일찍 잠자리에 들어도 수면의 질이 좋지 않아요.

   My sleep quality has been poor even when I go to bed early.

   일찍

   early

   잠자리에 들어도

   even when going to bed

   수면의 질

   sleep quality

   좋지 않아요

   is not good; is poor

   More detail

   일찍 means “early” and is an adverb, so it tells us when an action happens. It is useful with verbs such as 자다 “to sleep” or 일어나다 “to get up”: 일찍 자요 means “I go to sleep early.” The related adjective is 이르다 “to be early,” while 일찍 is the adverb used here. 잠자리에 들어도 contains the reusable expression 잠자리에 들다, “to go to bed.” In this expression, 들다 combines with 잠자리 to form that meaning; it should not be understood here simply as “to enter.” The ending -어도 gives a concessive meaning such as “even when” or “even if.” Here, going to bed early is presented as a condition that does not improve the result. The subject of this clause is omitted in Korean; the fixed translation identifies it as the speaker: “I go to bed.” 수면의 질 is a noun phrase meaning “sleep quality.” 수면 means “sleep” in more formal or health-related vocabulary, while 질 means “quality.” The particle 의 links the two nouns, so the pattern A의 B can mean “B of A” or “A’s B”: 음식의 질 means “food quality.” 좋지 않아요 is the polite present negative form of 좋다, “to be good.” The pattern -지 않다 negates an adjective or verb: 편하지 않아요 means “it is not comfortable.” With 좋다, 좋지 않아요 literally means “is not good” and naturally describes the quality here as “is poor.” The subject is 수면의 질, not the omitted subject of 들어도. Together, 일찍 modifies 잠자리에 들어도: “even when [I] go to bed early.” That concessive clause is followed by 수면의 질이 좋지 않아요: “sleep quality is not good.” The complete meaning is “My sleep quality has been poor even when I go to bed early.”

2. 저녁 시간에는 보통 어떻게 지내요?

   What does your evening routine look like?

   저녁

   evening

   시간

   time

   보통

   usually

   어떻게

   how

   지내요

   spend time

   More detail

   저녁 means “evening” here. It is a noun and can combine with other nouns to specify an evening-related time or activity, as in 저녁 식사 (“dinner/evening meal”). In this sentence, it sets the time period being asked about. 시간 means “time.” The noun phrase 저녁 시간 means “evening time” or “the evening period.” Korean commonly places a modifying noun before the noun it specifies: 저녁 modifies 시간. 보통 means “usually” or “typically.” It is an adverb, so it describes the general pattern of the activity rather than a single exceptional evening. For example, 보통 커피를 마셔요 means “I usually drink coffee.” 어떻게 means “how” and asks about the manner or way something happens. In this sentence, it asks about the way the person spends the evening, rather than asking for a specific time. A useful contrast is 언제 (“when”), which asks about timing. 지내요 is the polite present form of 지내다. In this context, 지내다 means “to spend or pass time,” so 지내요 means “spend time” in a polite question. The ending -요 marks a polite conversational style. Together, 저녁 시간에는 means “during the evening,” with -에는 marking that time period as the topic or setting. 보통 어떻게 지내요? asks “how do you usually spend it?” The complete utterance means “What does your evening routine look like?” or, more literally, “How do you usually spend your evenings?”

3. 저녁 식사 후에 커피를 마시고 침대에서 휴대폰을 봐요.

   I drink coffee after dinner and check my phone in bed.

   저녁 식사

   dinner

   후에

   after

   커피

   coffee

   마시고

   drink and then

   침대

   bed

   휴대폰

   mobile phone

   봐요

   check; look at

   More detail

   저녁 식사 means “dinner.” 식사 is a noun meaning a meal, while 저녁 specifies the evening meal. The phrase can be reused in 저녁 식사를 해요 (“I have dinner”), where 를 marks it as the object. 후에 means “after.” 후 is a noun meaning “after/afterward,” and 에 marks the relevant time. In 저녁 식사 후에, it creates the reusable pattern [event] 후에 (“after [event]”). For example, 수업 후에 만나요 means “Let’s meet after class.” 커피 is the loanword for “coffee.” Here it is the object of the following verb; Korean commonly marks that role with 를, as in 커피를 마셔요 (“I drink coffee”). 마시고 comes from 마시다, “to drink.” The ending -고 connects this action to the next one: 마시고 ... 봐요 means “drink ... and then check/look at ...” in this sentence. The subject is not repeated; the fixed translation identifies it as “I.” A reusable pattern is [verb stem]-고 [next action] for linking actions, as in 밥을 먹고 공부해요 (“I eat and study”). 침대 means “bed.” With the location particle 에서, the expression 침대에서 means “in/on the bed” as the place where the next action occurs. 에서 marks the place where an action happens; it is different from 에, which commonly marks a destination or a static location. 휴대폰 means “mobile phone” or “cell phone.” It is the object of 봐요, so the full object phrase is 휴대폰을 봐요; 을 marks 휴대폰 as the object. The same noun can be used in 휴대폰이 있어요 (“There is a phone / I have a phone”), where 이 marks it differently. 봐요 is the polite present form of 보다, “to see, look at, watch, or check.” In this utterance, the fixed translation selects the meaning “check my phone.” The form is built from 보- plus the polite ending -아요; 보아요 contracts to 봐요. The object and context determine the natural English rendering, so 보다 is not limited to one English verb. Together, 저녁 식사 후에 sets the time as “after dinner.” 커피를 마시고 gives the first linked action, “drink coffee,” and 침대에서 휴대폰을 봐요 gives the second action and its location, “check my phone in bed.” The complete utterance therefore means: “I drink coffee after dinner and check my phone in bed.”

4. 카페인과 화면을 보는 시간은 둘 다 긴장을 풀기 어렵게 만들 수 있어요.

   Both caffeine and screen time can make it harder to wind down.

   카페인

   caffeine

   화면

   screen

   보는

   watching; looking at

   시간

   time

   둘 다

   both

   긴장을 풀기

   unwinding; relaxing

   어렵게

   with difficulty; hard

   만들 수 있어요

   can make; can cause

   More detail

   카페인 means caffeine here. It is a noun, and 카페인과 adds 과, a connective meaning “and,” so it links this noun with the next noun phrase. 화면 means screen. In this sentence it is part of 화면을 보는 시간, literally “time spent looking at a screen.” The particle 을 marks 화면 as what is looked at. 보는 comes from the verb 보다, “to look at” or “to watch.” The ending -는 makes a present-action modifier before a noun: 보는 시간 is “time when one looks at [it]” or more naturally “time spent looking at [it].” The observed form is 보는; its base form is 보다. 시간 means time. In 화면을 보는 시간, it is the noun being modified by the preceding clause, so the whole phrase means “screen-viewing time” or “time spent looking at a screen.” 둘 다 means “both,” referring to the two linked factors, 카페인 and 화면을 보는 시간. 둘 means “two,” while 다 adds the sense “both/all of them.” 긴장을 풀기 comes from 긴장을 풀다, “to relax” or “to release tension.” 긴장 means tension, and 풀다 means to loosen or release; together they form the useful expression “to unwind.” The ending -기 changes the verb phrase into a noun-like unit: 긴장을 풀기 is “relaxing” or “to unwind.” 어렵게 is the adverbial form of 어렵다, “to be difficult.” Here it describes the result caused by the sentence’s subjects: they make unwinding difficult. 어렵게 만들다 is a reusable pattern meaning “to make something difficult.” 만들 수 있어요 comes from 만들다, “to make,” plus -(으)ㄹ 수 있다, “can” or “be able to,” in the polite present form 있어요. With 어렵게, the pattern 어렵게 만들 수 있어요 means “can make [it] difficult.” The subject of 만들다 is the paired subject marked by 둘 다. Putting the parts together: 카페인과 links caffeine with 화면을 보는 시간; 둘 다 says that both factors are included. Both can 긴장을 풀기 어렵게 만들 수 있어요, “make it difficult to unwind.” Thus the whole utterance means: “Both caffeine and screen time can make it harder to wind down.”

5. 한꺼번에 모든 것을 바꿀 수는 없어요.

   I cannot change everything at once.

   한꺼번에

   all at once

   모든

   all, every

   것

   thing

   바꿀

   change

   수는 없어요

   there is no possibility

   More detail

   한꺼번에 means doing several things together in one batch, rather than separately over time. It is a useful adverb for “all at once” or “in one go.” Example: 한꺼번에 먹지 마세요. — “Please don’t eat it all at once.” 모든 means “all” or “every” and comes before the noun or noun-like expression it describes. Here it modifies 것, so 모든 것 means “everything.” 모든 is not the noun itself; compare 모든 문제 (“all the problems”) and 모든 사람 (“everyone/all people”). 것 is a noun meaning “thing.” In 모든 것, it creates the general expression “everything.” The form 것 can also refer to an action or situation when used in a larger grammatical pattern, but here it refers broadly to things being changed. 바꿀 is the form of 바꾸다, “to change,” used before 수 in the ability/possibility pattern -(으)ㄹ 수 있다/없다. 바꿀 수 있다 means “can change,” while 바꿀 수 없다 means “cannot change.” The -ㄹ form here is attached to 바꾸다 because its stem ends in a vowel: 바꾸- + -ㄹ → 바꿀. 수는 없어요 completes the negative possibility pattern. 수 means a way or possibility, and 없어요 means “does not exist” in this construction; together with 바꿀, 바꿀 수 없어요 means “cannot change.” The particle 는 adds contrast or emphasis to the impossibility. 없어요 is the polite present style; a more formal version is 없습니다. Together, 모든 것을 바꿀 수는 없어요 means “it is not possible to change everything,” and 한꺼번에 specifies that the attempted change would be “all at once.” Thus the whole utterance means: “I cannot change everything at once.”

6. 저녁 식사 후에 커피를 마시지 않는 것처럼 현실적인 변화 하나부터 시작해 보세요.

   Start with one realistic change, like skipping coffee after dinner.

   저녁 식사

   dinner

   후에

   after

   커피

   coffee

   마시지 않는

   not drinking

   것처럼

   like; as if

   현실적인

   realistic

   변화

   change

   하나

   one

   부터

   starting with

   시작해 보세요

   try starting

   More detail

   저녁 식사 means “dinner” here. 식사 is the noun “meal,” and 저녁 식사 is the common combination for the evening meal. Example: 저녁 식사 후에 산책해요. — “I take a walk after dinner.” 후에 follows a time or event noun and means “after.” The particle 에 marks the point in time. Pattern: N 후에 = “after N.” 커피 is “coffee.” It is a loanword used as a noun. Example: 아침에 커피를 마셔요. — “I drink coffee in the morning.” 마시지 않는 comes from 마시다 (“to drink”) plus the negative pattern -지 않다 and the noun-modifying ending -는. Thus, 마시지 않는 means “not drinking” when it modifies a following noun or noun-like expression. The observed form is not the polite sentence ending; compare 커피를 마시지 않아요 — “I do not drink coffee.” 것처럼 consists of 것 (“thing” or an event expressed as a noun-like unit) and 처럼 (“like; as if”). After the preceding clause, it presents that situation as an example or comparison. In this sentence, the intended meaning is “like skipping” coffee, rather than a separate claim about an unreal situation. A reusable pattern is V-는 것처럼 — “like doing V” or “as if doing V,” depending on context. 현실적인 means “realistic” or “practical.” It modifies a noun; its base adjective is 현실적이다, and 현실적인 is the form used before a noun. Example: 현실적인 계획을 세워요. — “I make a realistic plan.” 변화 is the noun “change.” In this sentence it means a change in one’s behavior or routine. Example: 작은 변화를 시작했어요. — “I started a small change.” 하나 means “one” here and identifies a single change. Korean can place this native numeral after the noun, as in 변화 하나 (“one change”). This is the specific one-item meaning supported by the fixed translation. 부터 marks the starting point: N부터 means “starting with N” or “from N.” The pattern A부터 시작하다 is useful for saying “start with A.” Here, 하나부터 means to begin with one change. 시작해 보세요 is 시작하다 (“to start”) combined with -아/어 보다 (“try doing”) and the polite ending -세요. It therefore gives encouraging advice: “try starting.” The 보다 here is part of the auxiliary construction, not the independent meaning “see.” Example: 천천히 읽어 보세요. — “Try reading slowly.” Together, 저녁 식사 후에 커피를 마시지 않는 것처럼 gives the example “like skipping coffee after dinner.” 현실적인 변화 하나부터 means “starting with one realistic change,” and 시작해 보세요 politely encourages the listener to try beginning that way. The whole utterance means: “Start with one realistic change, like skipping coffee after dinner.”

7. 그럼 잠자리에 들기 전에 휴대폰을 보는 시간을 독서로 바꿀 수 있겠네요.

   Then I can replace phone time with reading before bed.

   그럼

   then

   잠자리에 들기 전에

   before going to bed

   휴대폰

   mobile phone

   보는 시간을

   the time spent looking

   독서로

   with reading

   바꿀

   change or replace

   수 있겠네요

   seems possible

   More detail

   그럼 means “then” here, linking this conclusion to the preceding suggestion. It is a useful conversational connector for moving from a condition or discussion to a resulting idea. 잠자리에 들기 전에 means “before going to bed.” 잠자리에 들다 is a set expression meaning “go to bed”; 들다 itself has several meanings, so its meaning here comes from this expression. -기 전에 attaches to a verb form to mean “before doing …”: 출발하기 전에 means “before departing.” 휴대폰 means “mobile phone” or “cell phone.” It is a noun and can be used directly before another noun to specify what kind of time or use is meant, as in 휴대폰 사용 (“mobile-phone use”). 보는 시간을 refers here to “the time spent looking at [the phone].” The verb 보다 means “to look at” or “to watch,” and 보는 is its present attributive form, used before 시간 to describe the activity associated with that time. The -을 ending marks 시간 as the object of the following verb 바꾸다; it does not mean that 보는 itself is the object. In 휴대폰을 보는, 휴대폰을 is the object of 보다, so the phrase literally organizes as “the time of looking at the phone.” A reusable pattern is V-는 시간: “the time spent V-ing.” For example, 운동하는 시간을 늘렸어요 means “I increased the time spent exercising.” This example introduces a new situation and is not part of the supplied conversation. 독서로 means “to reading” or “by replacing it with reading.” 독서 is the noun “reading,” especially reading as an activity, and -로 marks what something is changed into or replaced with in this construction. Thus A를 B로 바꾸다 is a reusable pattern meaning “to change or replace A with B.” 바꿀 comes from the base verb 바꾸다, “to change” or “to replace.” The -ㄹ form makes it modify the following 수, as in 바꿀 수 있다, “can change/replace.” Here it is not a completed-past form; the possible replacement is presented as an action under consideration. 수 있겠네요 expresses that something appears possible, with a tone of realization or inference: “it seems I can …” or “I guess it would be possible to ….” 수 있다 is the ordinary possibility pattern, while -겠네요 adds the speaker’s recognition of that possibility in the current situation. In this sentence, it does not assert that the replacement has already happened. Putting the parts together, 그럼 gives the conclusion, 잠자리에 들기 전에 sets the time, and 휴대폰을 보는 시간을 identifies the activity-time being changed. 독서로 바꿀 수 있겠네요 says that this time can apparently be replaced with reading. The whole utterance means: “Then I can replace phone time with reading before bed.”

8. 완벽한 루틴보다 지킬 수 있는 루틴이 더 중요해요.

   A routine you can keep matters more than a perfect one.

   완벽한

   perfect

   루틴

   routine

   보다

   than; compared with

   지킬 수 있는

   that you can keep

   더 중요해요

   is more important

   More detail

   완벽한 comes from the descriptive verb 완벽하다 (“to be perfect”). Its -한 form places it before a noun: 완벽한 루틴 means “a perfect routine.” This form describes the noun that follows; it is not a separate noun form. 루틴 is a noun meaning “routine.” It appears twice in the sentence: first as the routine used for comparison, and later as the routine that can be kept. Korean commonly repeats a noun when the two sides of a comparison need to be clear. 보다 is a comparison particle attached to the reference: A보다 B means “B compared with A” or “B more than A.” For example, 차보다 버스가 편해요 means “The bus is more convenient than the car.” 지킬 수 있는 means “that can be kept.” The lexical verb is 지키다, “to keep, follow, or adhere to” something such as a routine or promise. -을 수 있다 expresses ability or possibility; here 지킬 수 있다 means “can keep.” In 지킬 수 있는, 있다 takes the attributive form 있는, so the whole construction modifies the following noun: 지킬 수 있는 루틴, “a routine you can keep.” 더 중요해요 means “is more important.” The adjective is 중요하다, “to be important”; 중요해요 is its polite present-style form. 더 adds the comparative meaning “more,” so 더 중요해요 is stronger than simply 중요해요 (“is important”). Together, 완벽한 루틴보다 sets up “than a perfect routine,” while 지킬 수 있는 루틴이 marks “a routine you can keep” as the thing being evaluated. The pattern A보다 B가 더 + adjective means “B is more [adjective] than A.” Thus the whole utterance means: “A routine you can keep matters more than a perfect one.”

9. 결과를 판단하기 전에 짧은 기간 동안 그 방법을 시험해 볼 수 있어요.

   I can test that for a short period before judging the result.

   결과를

   the result

   판단하기 전에

   before judging

   짧은

   short

   기간

   period

   동안

   during; for

   그

   that

   방법

   method

   시험해

   test

   볼 수 있어요

   can

   More detail

   결과를 means “the result” here. 결과 is the noun “result,” and -를 marks it as the object of the later action 판단하다 (“to judge”). The same object marker appears after other nouns ending in a vowel or consonant; its form changes according to the noun’s final sound: -를 after a vowel, -을 after a consonant. Example: 계획을 세워요. — “I make a plan.” 판단하기 전에 means “before judging.” 판단하다 is “to judge” or “to assess”; its -기 form turns the verb into an activity or event, and 전에 means “before” that activity. The pattern 동사-기 전에 is reusable: 자기 전에 책을 읽어요. — “I read a book before sleeping.” The object 결과를 comes before this phrase, so the sentence specifies what is judged before the testing takes place. 짧은 means “short” in its attributive form. Its base adjective is 짧다; before a noun, it appears as 짧은, as in 짧은 기간 (“a short period”). This adjective describes duration here, not physical length. Example: 짧은 회의였어요. — “It was a short meeting.” 기간 is the noun “period” or “length of time.” In 짧은 기간, it names the span during which the testing happens. A related but different time word is 시간, which often refers to time or an amount of time more generally; 기간 emphasizes a bounded duration. 동안 marks the time span during which something continues, giving “during” or “for” in this sentence. The pattern 명사 + 동안 can describe a period: 한 달 동안 운동했어요. — “I exercised for one month.” Here 짧은 기간 동안 means “for a short period.” 그 is the demonstrative “that” before a noun. It identifies 방법 as a particular method understood from the situation; Korean demonstratives also distinguish 이 (“this”), 그 (“that”), and 저 (“that over there”). The form 그 itself does not show the noun’s number or gender. 방법 means “method” or “way.” In 그 방법, it is the thing being tested. Example: 새 방법을 찾았어요. — “I found a new method.” The object marker in that example is -을 because 방법 ends in a consonant; in the supplied sentence, 방법 is followed by 을 as part of 방법을. 시험해 comes from 시험하다, “to test.” The ending -해 is the connected form of this 하다-verb, linking it to the following construction. With 보다, 시험해 보다 means “to try testing” or “to test out,” rather than merely naming a test as a completed fact. Example: 새 앱을 시험해 봤어요. — “I tried testing the new app.” 볼 수 있어요 contributes “can.” In 시험해 볼 수 있어요, 보다 follows the connected verb and helps form the “try doing” expression, while -ㄹ 수 있다 expresses ability or possibility; the polite present ending is -어요. Thus, the whole ending presents testing as something the speaker can do. Example: 내일 만날 수 있어요. — “I can meet tomorrow.” Putting the parts together: 결과를 판단하기 전에 sets the time relation, “before judging the result.” 짧은 기간 동안 gives the testing duration, and 그 방법을 시험해 볼 수 있어요 says that the speaker can test that method. The complete meaning is: “I can test that for a short period before judging the result.”

10. 그러면 몸이 적응할 시간이 충분해져요.

    That gives your body enough time to adjust.

    그러면

    then; in that case

    몸

    body

    적응할

    to adjust; to adapt

    시간

    time

    충분해져요

    becomes sufficient; becomes enough

    More detail

    그러면 means “then” or “in that case.” It links this sentence to a situation just mentioned and introduces its consequence. 몸 means “body.” It is a noun, and the form does not show number by itself. Here, in 몸이 적응할 시간, it is the subject of the embedded clause “the body adjusts”; the translation identifies that body as “your body.” Korean does not need a separate word for “your” in this sentence. 적응할 comes from 적응하다, “to adapt” or “to adjust.” The ending -ㄹ makes an attributive form that modifies a following noun: 적응할 시간 means “time for the body to adjust” or “time to adjust.” This differs from 적응해요, the polite present-style form meaning “adjusts” or “is adjusting.” 시간 means “time.” In 적응할 시간, it is the noun modified by 적응할. A reusable pattern is [verb + -ㄹ] + 시간, as in 쉴 시간 (“time to rest”). 충분해져요 means “becomes enough” or “becomes sufficient.” It comes from 충분하다 (“to be sufficient”) with -아/어지다, which expresses a change into a state: 충분해지다 means “to become sufficient.” The polite present-style ending is -어요. This differs from 충분해요 (“is enough”), which describes sufficiency without emphasizing the change. Together, 그러면 introduces the consequence, 몸이 적응할 시간 means “time for your body to adjust,” and 충분해져요 says that this time becomes sufficient. The whole utterance therefore means: “That gives your body enough time to adjust.”
