When To Use It
this week에 대해 말하고 있는데 아직 수요일이라면 주의해야 합니다.last week에 대해 말하고 있다면 그 시간은 이미 과거의 일입니다. 역사책에나 나올 법한 일이죠. 구체적인 날짜(I graduated in 2022.)나 상대적인 시간(I ordered Uber Eats an hour ago.)에 사용합니다.I played Minecraft every day last summer. (지난 여름에는 매일 마인크래프트를 했어.) 지금은 대학교 공부 때문에 바쁘죠? 아니면 발로란트로 갈아탔나요?Last night으로 이야기를 시작하면 친구들은 과거의 일을 들을 준비를 합니다.last month 복권 당첨 번호를 좀 알려주세요.
Common Mistakes
yesterday night라고 말하기. 논리적으로는 맞는 것 같지만 영어에서는 그렇게 말하지 않습니다. 대신last night을 사용하세요. 영어는 가끔 이렇게 이상합니다. 그냥 받아들이고 넘어가세요. 주차로(driveway)에 주차하고 공원도로(parkway)를 달리는 것만큼이나 이상한 일이니까요.- 연도 앞의
in잊어버리기.I moved 2019는 틀린 표현입니다.I moved in 2019라고 해야 합니다. 연도는 살기 위한 작은 '집'이 필요하거든요. ago를 엉뚱한 곳에 두기.I saw him ago two days는 전형적인 실수입니다. 숫자가 먼저 와야 합니다.I saw him two days ago입니다. 카운트다운처럼 생각하세요. 3, 2, 1... ago(전)!- 과거형과 함께
since사용하기.I lived here since two years는 어색합니다.I moved here two years ago를 사용하세요.since는 현재완료형용입니다. 둘을 섞어 쓰면 문법 경찰이 출동할 거예요. 사이렌은 없지만 아주 빨간 펜을 들고 있죠. day와 함께last사용하기. 보통yesterday라고 말하며last day라고는 하지 않습니다. 판타지 소설에서 '왕국의 마지막 날(Last Day of the Kingdom)'이라면 모를까, 틱톡 캡션에는yesterday를 사용하세요.
Contrast With Similar Patterns
- 과거형 vs. 현재완료형: 과거형은 완전히 끝난 시간에 사용합니다.
I went to London in 2018.현재완료형은 아직 끝나지 않은 시간이나 일반적인 경험에 사용합니다.I have been to London.차이를 아시겠나요? 첫 번째는 구체적인 날짜가 있습니다. 두 번째는 인생에서의 단순한 사실입니다. '언제' 일어났는지 말한다면 거의 항상 과거형이 필요합니다. - Ago vs. For:
ago는 '지금'으로부터 얼마나 거슬러 올라가는지 알려줍니다.I started studying two hours ago. (2시간 전부터 공부를 시작했어.)(이미 뇌가 녹고 있어요).for는 기간을 알려줍니다.I studied for two hours. (2시간 동안 공부했어.)과거의 일에도for를 쓸 수 있습니다.I lived in Spain for three years.하지만 그 기간이 언제 끝났는지 말하고 싶다면 시간 표현을 사용하세요.I lived in Spain for three years until 2021. - Yesterday vs. The other day:
yesterday는 정확히 1일 전입니다.the other day는 최근 과거의 모호한 시점입니다. 3일 전일 수도 있고 1주일 전일 수도 있죠. 달력을 확인하기 귀찮을 때 쓰기 딱 좋은 표현입니다.
Quick FAQ
last morning이라고 할 수 있나요?
아니요, yesterday morning을 사용하세요. 밤에는 last night을 쓰지만 아침이나 낮은 yesterday를 씁니다. 이해가 안 가죠? 역사를 탓하세요.
this morning은 과거인가요, 현재인가요?
둘 다입니다! 오전 10시라면 this morning은 '지금'입니다. 오후 4시라면 this morning은 '과거'입니다. 문맥이 전부입니다. '괜찮아(fine)'라는 말이 톤에 따라 최고일 수도 최악일 수도 있는 것과 같죠.
ago는 어디에 두나요?
항상 시간 뒤에 둡니다. One minute ago, five weeks ago. 절대 ago five weeks라고 하지 않습니다.
연도에 at을 쓸 수 있나요?
아니요, in을 씁니다. In 2024. 정확한 시간은 at입니다. At 5:30.
when I was young은 어떤가요?
이것도 시간 표현에 포함됩니다! 마음은 늘 젊지만, 인생의 끝난 한 시기를 가리키니까요.
last week은 대문자로 시작하나요?
문장의 맨 앞에 오지 않는 한 소문자입니다. 크리스마스처럼 특별한 이름이 아니니까요.

Smart Tips
Think of 'ago' as a 'backwards arrow' that always points from the number to the past.
If it's a day, use 'yesterday'. If it's a period like 'week' or 'month', use 'last'.
Always pair 'night' with 'last', never 'yesterday'.
Stop! 'Yesterday', 'ago', and 'last' are strong enough to stand alone without prepositions.
발음
Yesterday
Stress the first syllable: YES-ter-day.
Ago
The 'a' is a schwa sound (uh). Stress the second syllable: uh-GO.
Last night
The 't' in 'last' often blends into the 'n' in 'night' in fast speech (elision).
Time Emphasis
I saw him YESTERDAY. (Falling tone on yesterday)
Emphasizing exactly when it happened to correct a misunderstanding.

Americans often use 'yesterday' as an adjective in news headlines.
'Yesterday' comes from Old English 'geostran' (yester) and 'dæg' (day). 'Ago' comes from the Middle English 'agone', meaning 'passed away' or 'gone by'.

자주 묻는 질문 (8)
No. 'Ago' refers to a finished time, so you must use the Past Simple. Say 'I saw him two days ago', not 'I have seen him two days ago'.
'Last week' means the week before this one. 'The last week' usually refers to a duration of 7 days or the final week of a specific event.
It is very rare and usually considered incorrect. Native speakers almost always say 'last night'.
No, you should say 'yesterday morning'. Similarly, use 'yesterday afternoon'.
Yes, 'ago' always follows the time duration (e.g., 'a long time ago').
No, 'last' refers to the past. For the future, use 'next' (e.g., 'next week').
No. In English, we say 'last Monday' without 'on'.
'Ago' is used for time back from now. 'Before' is used for time back from another point in the past.
