   More detail

   제 means “my” here. It is the possessive form related to the polite first-person pronoun 저: 저의 is commonly shortened to 제. It modifies the following noun, as in 제 카드 (“my card”). 카드 is the noun “card.” Korean nouns do not change for singular versus plural in this form; the context and any counters or plural markers provide that information when needed. 거절됐지만 means “was declined, but.” The useful base expression is 거절되다 (“to be declined/rejected”), and 거절됐어요 is its past polite form. The ending -지만 adds “but/although”: 거절됐지만 = “was declined, but …”. Example: 신청이 거절됐지만 다시 시도했어요. — “The application was declined, but I tried again.” 계좌 means “account,” especially a financial account. Example: 계좌를 확인했어요. — “I checked the account.” 아직 means “still” in this sentence, indicating that the expected condition continues at this point. With a negative clause, it can also mean “not yet,” as in 아직 도착하지 않았어요. — “It has not arrived yet.” 활성 is used here with 상태 in the expression 활성 상태, meaning “active status” or “an active state.” It is a noun-like technical term meaning that something is active; it is not an inflected form of the nearby noun 상태. A common related expression is 활성화되다, “to become/be activated,” but that is a different form and is not the form used here. 상태 means “state” or “status.” In 활성 상태, it identifies the condition in which the account is active. Example: 현재 계좌 상태를 확인하세요. — “Please check the current account status.” 여야 해요 is part of the construction N(이)어야 해요, meaning that something must or should be N. After a noun ending in a consonant, 이어야 해요 is used; after a noun ending in a vowel, 여야 해요 is used. Here 상태 ends in a vowel sound, so 상태여야 해요 means “it should/must be in that state.” The ending -아/어야 하다 expresses a required or expected condition, and the polite ending -요 makes the sentence polite. Example: 오늘은 휴일이어야 해요. — “Today should be a day off.” Together, 제 카드가 거절됐지만 says “my card was declined, but,” and 계좌는 아직 활성 상태여야 해요 says “the account should still be in an active state.” The topic marker 는 contrasts the account with the card, while 아직 places the expected active condition at the current point in time. The complete meaning is: “My card was declined, but the account should still be active.”

2. 시스템에서 비정상적인 활동을 감지한 후 카드가 차단됐을 수도 있어요.

   More detail

   시스템 means “system” here. The particle 에서 in 시스템에서 marks the place or source where an action occurs, so the system is presented as the source of the detection. Example: 앱에서 오류를 찾았어요. — “The app found an error.” 비정상적인 means “unusual” or “abnormal” and describes the following noun 활동. It is the attributive form of 비정상적이다; the ending -인 lets this descriptive form modify a noun. Example: 비정상적인 로그인 — “an unusual login.” 활동 means “activity.” In this sentence it refers to the unusual activity that the system detected. Example: 활동을 확인했어요. — “I checked the activity.” 감지한 means “detected.” It comes from 감지하다, “to detect,” and the ending -한 makes the verb modify a following noun-like time expression: 감지한 후 means “after detecting.” The detecting action is presented as completed before the later event. Example: 문제를 감지한 후 알림을 보냈어요. — “After detecting the problem, [someone] sent a notification.” 후 means “after” when it follows an event or action. The pattern 동사-(으)ㄴ 후 means “after doing something”: 확인한 후 — “after checking.” Here, 감지한 후 means “after detecting [the unusual activity].” 카드 means “card.” The fixed translation identifies it as the card that may have been blocked. Example: 카드를 다시 사용해 보세요. — “Please try using the card again.” 차단됐 means “was blocked.” It is the visible contracted form of 차단되었-, from the passive verb 차단되다, “to be blocked,” with past marking. The verb 차단하다 means “to block” actively, while 차단되다 presents the card as receiving that action. Example: 접근이 차단됐어요. — “Access was blocked.” 을 수도 있어요 expresses possibility: “may” or “might.” After a past form, the pattern -았/었을 수도 있어요 means “may have done” or “may have been [in a past state].” Thus 차단됐을 수도 있어요 means “may have been blocked,” not a definite claim that it was blocked. Example: 이미 출발했을 수도 있어요. — “They may have already left.” Together, 시스템에서 비정상적인 활동을 감지한 후 sets the time sequence: after the system detected unusual activity. 카드가 차단됐을 수도 있어요 says that the card may have been blocked. The complete meaning is: “It may have been blocked after the system flagged unusual activity.”

3. 최근에 여행 중이었는데, 그게 원인이었을 수도 있겠네요.

   I was traveling recently, so that might have triggered it.

   최근에

   recently

   여행

   travel; trip

   중이었는데

   was in the middle of, but

   그게

   that

   원인

   cause

   었을 수도 있겠네요

   might have been

   More detail

   최근에 means “recently.” It is an adverb built from 최근 (“recent”) and marks a time close to now. It can be moved to another position when the intended time reference remains clear. 여행 means “travel” or “a trip.” In this sentence it appears in the reusable pattern 여행 중이다, “to be traveling / to be on a trip.” 여행 is a noun; the related verb is 여행하다, “to travel,” but the observed form itself is not that verb. 중이었는데 expresses being in the middle of an activity in the past, with a following connection such as “but,” “and,” or “while.” The pattern 동사-(으)ㄴ/는 중이다 describes an activity in progress; here 중이었다 is its past form, and -는데 connects this clause to the next information. Thus 여행 중이었는데 presents the speaker’s recent travel as background for the possible explanation that follows. 그게 is the contracted subject form of 그것이: 그것 (“that/it”) plus the subject marker 이. Here it means “that” as the circumstance being considered as a possible cause. The exact referent is understood from the surrounding situation rather than identified by a separate noun in this sentence. 원인 means “cause” or “reason.” With the copula, 원인이다 means “to be a cause”; with a noun such as 문제, the same pattern is 문제의 원인이다, “to be the cause of the problem.” In this sentence, 원인 is the noun carrying the meaning “cause.” 었을 수도 있겠네요 combines past possibility with a tentative realization. The relevant pattern is -을/ㄹ 수도 있다, “may/might,” and its past form before 수도 is -었을 수도 있다, “may/might have been or happened.” 겠네요 adds a speaker’s tentative inference or recognition, often naturally rendered here as “I suppose” or simply “might.” The past marking belongs to the copular expression 원인이었다 (“was a cause”), not to the noun 원인 itself. The ending -네요 gives the utterance a mild noticing or realization tone. Putting the parts together: 최근에 sets the time, 여행 중이었는데 says that the speaker was traveling recently and supplies background, 그게 identifies that circumstance as the subject under discussion, and 원인이었을 수도 있겠네요 presents it as a tentative past cause. The complete meaning is: “I was traveling recently, so that might have triggered it.”

4. 그렇다면 이해가 되지만, 그래도 신원을 확인해야 해요.

   That would make sense, but we still need to verify your identity.

   그렇다면

   if so; then

   이해가 되지만

   makes sense, but

   그래도

   still; nevertheless

   신원

   identity

   확인해야 해요

   need to verify

   More detail

   그렇다면 means “if that is so” or “then, in that case.” It introduces a condition based on something already mentioned. In this sentence it links the earlier possibility to the conclusion that follows. A reusable pattern is 그렇다면 + clause: 그렇다면 시작해요. — “Then, let’s start.” 이해가 되지만 uses 이해가 되다, literally “understanding becomes possible,” for “make sense” or “be understandable.” This is different from 이해하다, “to understand,” which presents someone as actively understanding something. The ending -지만 adds a contrast: “although it makes sense” or “it makes sense, but…”. Example: 이 설명은 이해가 돼요. — “This explanation makes sense.” 그래도 means “even so,” “still,” or “nevertheless.” It signals that the next point remains true despite the preceding point. Example: 비싸지만 그래도 사고 싶어요. — “It’s expensive, but I still want to buy it.” 신원 is the noun “identity,” especially the identity of a person. It commonly appears in the construction 신원을 확인하다, “verify someone’s identity.” Example: 직원이 신원을 확인했어요. — “The staff member verified the person’s identity.” The noun itself does not state who the identity belongs to; here, the fixed translation identifies it as the listener’s identity. 확인해야 해요 is based on 확인하다, “to check” or “verify.” The pattern 동사-아/어야 하다 expresses necessity, so 확인해야 해요 means “need to verify” or “must verify.” 해요 is the polite present form of 하다 within this construction. Example: 서류를 확인해야 해요. — “I need to check the documents.” Putting the parts together, 그렇다면 sets up “if that is so,” 이해가 되지만 says that the situation makes sense while introducing a contrast, and 그래도 emphasizes that the next requirement remains. 신원을 확인해야 해요 says that identity verification is necessary. The whole utterance therefore means: “That would make sense, but even so, we still need to verify your identity.” The -요 ending makes the sentence polite and conversational.

5. 모든 구매 내역을 하나씩 확인하지 않고도 확인할 수 있을까요?

   Can we check that without going through every purchase?

   모든

   every; all

   구매 내역

   purchase records

   하나씩

   one by one

   확인하지 않고도

   without checking

   확인할 수 있을까요?

   Could we check?

   More detail

   모든 means “every” or “all” and modifies the noun that follows it. It does not itself state a numeric count; it presents the relevant set as a whole. 구매 내역 means “purchase record(s)” or “purchase history.” 구매 means “purchase,” and 내역 refers to a record or detailed listing of activity. Together, they form a reusable noun phrase for records of purchases. 하나씩 means “one by one” or “each individually.” The suffix -씩 distributes an action across items: 하나씩 확인하다 means “check them one by one.” It describes the manner of checking, not necessarily a claim that there is only one item. 확인하지 않고도 is built from 확인하다 (“to check” or “verify”), the negative form 확인하지 않다, and the connective pattern -지 않고 (“without doing”). The final 도 adds the sense “even,” so the phrase means “even without checking” or “without going through.” Pattern: V-지 않고도 = “even without V-ing.” 확인할 수 있을까요? uses 확인하다 with -(으)ㄹ 수 있다, the pattern for possibility or ability, followed by the polite question form -을까요?. Literally, it asks whether checking is possible; in this sentence, the fixed translation gives the natural meaning “Could we check it?” The subject is omitted in Korean, so the English “we” comes from the intended translation rather than from an overt Korean subject. Together, 모든 구매 내역을 marks all the purchase records as the object, and 하나씩 확인하지 않고도 says that they need not be checked individually. The final 확인할 수 있을까요? asks politely whether the relevant information can be checked by another method. Thus the complete utterance means: “Can we check that without going through every purchase?” The repeated 확인하다 is natural: the first occurrence describes the method being avoided, while the second describes the overall checking being requested. The ending is polite and appropriately tentative for a request or inquiry.

6. 신원 확인과 최근 활동에 대한 대략적인 파악만 필요해요.

   We only need identity confirmation and a general sense of recent activity.

   신원

   identity

   확인

   confirmation

   최근

   recent

   활동

   activity

   대략적인

   general; approximate

   파악

   understanding; grasp

   필요해요

   is needed

   More detail

   신원 means a person’s identity, especially the information used to establish who someone is. It is commonly used in 신원 확인 (“identity confirmation”); 신원 names what is being established, while 확인 names the act or result of checking it. 확인 is the noun “confirmation” or “checking” here. Its useful verb form is 확인하다, “to check” or “to confirm.” For example, 서류를 확인해요 means “I check the documents.” The noun 확인 can refer to the checking itself or to confirmation as a result. 최근 means “recent” and usually modifies a following noun, as in 최근 소식 (“recent news”). It is a time-related modifier; it does not itself mean that an activity is currently happening. 활동 means “activity” or “activities.” In 최근 활동, it refers generally to activity during the recent period. The related verb 활동하다 means “to be active” or “to engage in activities,” but the observed form here is the noun 활동. 대략적인 means “general” or “approximate.” It is the attributive form used before a noun, so 대략적인 파악 means “a general or approximate grasp.” The base descriptive form is 대략적이다; compare 대략적으로, “approximately,” when modifying an action or statement rather than a noun. 파악 means “grasp,” “understanding,” or “assessment” of a situation. Its related verb is 파악하다, “to grasp” or “to assess.” For example, 상황을 파악해요 means “I assess the situation.” In this sentence, 파악 is a noun coordinated with 확인 by 과. 필요해요 means “is needed” or “is necessary.” It is the polite 해요-style form of 필요하다. The sentence also contains 만 immediately before it: 확인과 ... 파악만 필요해요 means “only confirmation and ... understanding are needed.” 만 limits what is needed; it is not part of the meaning of 필요해요 alone. Together, 신원 확인과 최근 활동에 대한 대략적인 파악 means “identity confirmation and a general grasp of recent activity.” 에 대한 links 대략적인 파악 to its topic, “about recent activity.” The coordinated noun phrase is followed by 만 필요해요, giving the complete meaning: “We only need identity confirmation and a general sense of recent activity.”

7. 모든 거래 내역을 나열하는 것보다 그게 더 합리적으로 들리네요.

   That sounds more reasonable than listing every transaction.

   모든

   every; all

   거래 내역

   transaction history

   나열하는

   listing

   것보다

   than doing that

   그게

   that

   더

   more

   합리적으로

   reasonably

   들리네요

   sounds

   More detail

   모든 means “every” or “all” and comes before the noun it specifies. Here it gives 거래 내역 a complete-scope meaning: the utterance refers to the full set of transaction records, not just some of them. Example: 모든 서류를 확인했어요. — “I checked all the documents.” 거래 내역 is a noun phrase meaning “transaction history” or “transaction records.” 거래 means a transaction, while 내역 refers to a detailed record or breakdown. Together they form a useful compound expression for records of transactions. Example: 거래 내역을 확인해 주세요. — “Please check the transaction history.” 나열하는 comes from the verb 나열하다, “to list” or “to enumerate.” The ending -는 makes the verb modify a following noun, here the nominalizer 것; it presents the action as “listing.” The base verb is 나열하다, and 나열하는 is the form used before a noun for a present or general action. Example: 이름을 나열하는 일은 오래 걸려요. — “Listing the names takes a long time.” 것보다 consists of 것, a noun meaning “thing” or “the act of doing something,” and 보다, a comparison marker meaning “than.” After 나열하는, 것 turns “listing” into a noun-like expression, so 나열하는 것보다 means “than listing.” The comparison pattern is A보다 B: “B rather than A” or “B is more ... than A.” 그게 is the contracted form of 그것이: 그것 (“that thing”) plus the subject marker 이. In this utterance, it is the subject translated as “that.” The form 그게 is a reusable spoken contraction; the less contracted form is 그것이. Example: 그게 더 좋아요. — “That is better.” 더 means “more” or “to a greater degree.” It increases the degree of the following description. Here it combines with 합리적으로 to mean “more reasonably,” and the comparison is completed by 것보다: “more reasonable than listing ...” Example: 이 방법이 더 편해요. — “This method is more convenient.” 합리적으로 is the adverb “reasonably” or “in a rational way,” formed from the descriptive adjective 합리적이다 (“to be reasonable”) with the adverb-forming ending -으로. In this sentence it modifies 들리네요, describing how the subject sounds. The adjective form 합리적인 can modify a noun directly: 합리적인 선택 — “a reasonable choice.” 들리네요 comes from 들리다, “to be heard” or “to sound,” with the polite sentence ending -네요. With an adjective adverb such as 합리적으로, 합리적으로 들리다 means “to sound reasonable,” rather than simply “to be audible.” The ending -네요 presents the speaker’s current impression or assessment politely. Example: 좋은 생각으로 들리네요. — “That sounds like a good idea.” Taken together, 모든 거래 내역을 나열하는 것보다 sets up the comparison point: “than listing every transaction.” The subject 그게 is “that,” and 더 합리적으로 들리네요 says that it sounds more reasonable. The complete meaning is: “That sounds more reasonable than listing every transaction.” This wording politely presents the assessment as the speaker’s impression.

8. 신원이 확인되면 보통 바로 차단 조치를 검토할 수 있어요.

   Once your identity is verified, we can usually review the block right away.

   신원

   바로

   right away

   차단

   blocking

   조치

   measure

   검토할

   review

   수 있어요

   can

   More detail

   신원 means “identity,” especially a person’s identifying information or identity status. In this sentence, 신원이 is the subject-marked form: the identity is what becomes verified. Example: 신원을 확인했어요. — “I checked the identity.” 확인되면 is 확인되다 (“be verified/confirmed”) plus -면 (“when/if”). The passive-like form 확인되다 presents the identity as receiving verification, and -면 makes that condition temporal here: “once it is verified.” Example: 예약이 확인되면 알려 주세요. — “Please let me know once the reservation is confirmed.” 보통 means “usually” or “normally.” It modifies the following situation, so the review is presented as the usual course rather than an absolute result. 바로 means “right away” or “immediately.” It indicates that the review can happen without much delay after the condition is met. Example: 확인 후 바로 연락할게요. — “I’ll contact you right after checking.” 차단 is a noun meaning “blocking” or “a block.” It can refer to preventing access, contact, or activity, depending on context. Example: 차단을 해제했어요. — “I removed the block.” 조치 means “measure” or “action taken.” Together, 차단 조치 is a compact noun combination meaning “blocking measure” or “blocking action”; 차단 specifies the type of 조치. 검토할 is the attributive form of the verb 검토하다 (“to review,” “to consider carefully”). 검토하다 becomes 검토할 before 수 in the possibility pattern V-(으)ㄹ 수 있다: 검토할 수 있다 means “can review” or “it is possible to review.” The -ㄹ belongs to 검토하다, not to the noun 조치. 수 있어요 completes that possibility pattern. 수 is the dependent noun used in V-(으)ㄹ 수 있다, and 있어요 is the polite present form of 있다; together with 검토할, it expresses ability or possibility. Here the fixed translation supports the reading “we can review,” not a mere statement that review exists. Example: 지금 검토할 수 있어요. — “We can review it now.” Taken together, 신원이 확인되면 sets the condition, 보통 says what normally follows, and 바로 places it immediately after that condition. 차단 조치 is the object being considered, while 검토할 수 있어요 says that it can be reviewed. The whole utterance means: “Once your identity is verified, we can usually review the block right away.”
