Overview
I like you and your dog.(난 당신과 당신 개가 좋아요)라고 말합니다. 데이트 상대가 미소를 짓네요.
I like you, but your dog...(난 당신은 좋은데, 당신 개는...)이라고 말한다고 상상해 보세요. 상대방이 얼어붙을 거예요. 아주 작은 단어 하나가 그날 저녁의 분위기를 완전히 바꿔버렸죠.
And, but, 그리고 or는 영어라는 언어의 접착제와 같아요. 이 단어들이 없으면 우리는 마치 고장 난 로봇처럼 들릴 거예요.I like pizza. I like pasta. I like salad.지루하죠?
I like pizza, pasta, and salad.라고 말하고 싶잖아요. 이 단어들은 더 긴 문장을 만드는 데 도움을 줘요. 생각들을 연결해 주죠.
How This Grammar Works
And는 «더하기» 기호(+)예요. 정보를 더 추가하고 싶을 때 사용해요. 비슷한 것들을 연결하죠.I have an iPhone
계속해서 더해주니까 가장 친근한 접속사죠.anda MacBook.But은 «잠깐만» 표지판(≠)이에요. 차이점이나 놀라운 점을 보여주고 싶을 때 사용해요. 서로 반대되는 두 가지를 연결하죠.I want to go out,
이건 드라마를 더해줘요. 문맥을 더해주고요. 문법의butit is raining.반전(plot twist)이라고 할 수 있죠.Or는 «결정» 표지판(?)이에요. 선택권이 있을 때 사용해요. 둘 다 가질 순 없고, 하나만 가능할 때죠.Do you want tea
아직 결정을 못 했거나 선택지를 줄 때 사용해요.orcoffee?
등위 접속사(coordinating conjunctions)라고 불러요. 이름은 거창하게 들리지만, 그냥 동등한 중요성을 가진 두 가지를 연결한다는 뜻이에요. 두 단어(cats and dogs)를 연결할 수도 있고, 두 개의 완전한 문장(I like cats, and I like dogs)을 연결할 수도 있어요. 이것만 기억하세요: and는 더하고, but은 대조하고, or는 선택하는 거예요. 틱톡 댄스만큼 간단하지만 훨씬 더 유용하답니다.
Formation Pattern
Coffee or tea?
In the morning and at night.
I am tired, but I am happy.
but이 두 개의 완전한 문장을 연결할 때 보통 그 앞에 쉼표를 찍어요. and와 or의 경우, 문장이 아주 길지 않은 이상 쉼표는 선택 사항인 경우가 많아요.

| and | I like cats and dogs. | 저는 고양이와 개를 좋아해요. |
| but | I like cats, but I don't like dogs. | 저는 고양이는 좋아하지만, 개는 좋아하지 않아요. |
| or | Do you like cats or dogs? | 고양이를 좋아하나요, 아니면 개를 좋아하나요? |
Memory Trick
ABO를 기억하세요: And (Add/더하기), But (Backtrack/Contrast/되돌아가기 또는 대조), Or (Option/선택). 혈액형처럼 들리지만, 이건 기초 영어 문장을 위한 생명줄이에요!
When To Use It
- 친구에게 문자 할 때: "I'm at the mall
andI'm hungry." - 소셜 미디어:
Great view,
butso cold! ❄️ - 음식 주문할 때:
I want a burger
ora pizza. - 취업 면접 (Zoom):
I speak English
andSpanish. - 넷플릭스:
The show is good,
butthe ending is bad.
But why though?(근데 왜?) 또는 And then he left!(그리고 나서 걔 떠났어!)처럼요. 옛날 학교 영어 선생님은 기겁하실 수도 있지만, 이게 요즘 사람들이 진짜 말하는 방식이에요.
I went to Paris. I went to Berlin. I went to Rome.이라고 하는 대신,
I went to Paris, Berlin, and Rome.이라고 말해보세요.
Common Mistakes
- 1Run-on Sentence (쉬지 않고 이어지는 문장):
and를 너무 많이 쓰는 거예요.I went to the store
멈추세요! 마침표를 찍으세요.andI bought milkandI saw my friendandwe talkedand... - 2쉼표 빠뜨리기:
but앞에 쉼표를 잊어버리는 경우예요.I like him but I hate his music.
이렇게 써야 해요:I like him,
butI hate his music. - 3이중 접속사: 두 개를 한꺼번에 쓰는 거예요. ✗
I want water
✓but orjuice.I want water
orjuice. - 4목록에서 'And' 남용하기:
I like apples
영어에서는 쉼표를 사용하고andorangesandbananas.and는 마지막 항목 앞에만 넣어요:I like apples, oranges,
andbananas. - 5'But'과 'Or' 혼동하기:
Do you want milk
(이건 이상한 도전 과제처럼 들리네요). 선택할 때는butsugar?or를 쓰세요:Do you want milk
orsugar?
Contrast With Similar Patterns
so나 because와 헷갈려 해요.And는 정보를 추가함 vs.Because는 이유를 설명함. "I'm tiredandhungry« (두 가지 사실) vs. »I'm tiredbecauseI worked late" (이유).But은 대조를 보여줌 vs.So는 결과를 보여줌. "I'm tired,butI'm working« (대조) vs. »I'm tired,soI'm sleeping" (결과).Or는 선택을 보여줌 vs.Either...or(A2/B1 레벨). 일단은 간단한or만 계속 써보세요.
Quick FAQ
And로 문장을 시작해도 되나요?
네! 이메일이나 문자에서는 아주 흔해요. 격식 있는 글쓰기에서만 너무 많이 쓰지 않으면 돼요.
and 앞에는 쉼표가 필요한가요?
보통은 아니에요. 문장이 길거나 목록의 일부인 경우(«옥스포드 콤마»)가 아니라면요.
but과 however의 차이점은 뭔가요?
But은 단순하고 대화에서 쓰여요. However는 더 격식 있고 비즈니스나 학술적 글쓰기에 쓰이죠.
or는 질문에만 쓰이나요?
아니요.
We can go to the cinema or stay home. 같은 평서문에서도 쓸 수 있어요.
but으로 문장을 시작할 수 있나요?
물론이죠. 요점을 강조하기에 아주 좋은 방법이에요. "But wait, there's more!"(하지만 잠깐, 더 있어요!)

Smart Tips
Use the Oxford Comma to ensure each item is clearly separated and distinct.
Replace 'but' with 'yet' or 'however' (with proper punctuation).
Ensure all verbs are in the same tense and form.
Use 'or' to mean 'neither of these things'.
발음
Weak Form of 'And'
In natural speech, 'and' is often reduced to /ən/ or just /n/.
Glottal Stop with 'But'
In many British dialects, the 't' in 'but' is replaced by a glottal stop /bʌʔ/.
Linking 'Or'
When 'or' is followed by a vowel, the 'r' is often pronounced to link the words (e.g., 'tea or_apple').
Lists
Apples (rising), pears (rising), and bananas (falling).
Shows the list is finished.

The Oxford Comma is less common in UK journalism (like the BBC) but still used in academic writing (Oxford University Press).
The Oxford Comma is standard in most US style guides (APA, MLA, Chicago).
In legal documents, 'and/or' is frequently used to avoid ambiguity, though it is often criticized as clunky in general writing.
All three words have Old English roots: 'and' (and), 'but' (be-utan - meaning 'outside'), and 'or' (othther).

자주 묻는 질문 (8)
Yes, you can! It is common in modern writing for emphasis, though some very formal teachers might still discourage it.
It is the comma before the final 'and' or 'or' in a list of three or more items (e.g., 'A, B, and C').
Use a comma before 'but' when it connects two full sentences (independent clauses).
It means using the same grammatical form for all items in a list (e.g., 'I like running, jumping, and swimming').
In some cases, yes! 'Work hard and you'll pass' means 'If you work hard, you'll pass.'
It is common in legal and technical writing but should be avoided in creative or casual writing.
It's a mistake where you join two sentences with only a comma and no conjunction.
Usually, but it can also mean 'except', as in 'Everyone but me was there.'
