- Usually follow an adjective or 'the/which/this/that': 'Which one do you want?'
Overview
one과 ones가 구세주처럼 등장합니다. 이 작은 단어들은 영어 회화의 '복사-붙여넣기' 단축키와 같아요. 이미 언급한 명사를 대신할 수 있게 해주죠.I want the chocolate muffin이라고 말하지 않습니다. 너무 길거든요. 대신
I want the chocolate one이라고 말합니다.one이라는 단어가 muffin 자리를 대신하는 거죠. 이게 바로 대명사입니다. 셀 수 있는 명사를 대신해 주죠.ones를 사용합니다. Do you like the black shoes or the white ones? 여기서 ones는 shoes를 대신합니다.one'이라고 하면 아무도 원하지 않을 거예요. 그냥 이상하게 들리거든요.How This Grammar Works
one과 ones를 자리 표시자라고 생각하세요. 영화 속 스턴트맨 같은 존재죠. 주인공 명사가 먼저 힘든 일을 처리합니다.I like that one이라고 말할 수는 없어요. 그러면 유령을 가리키고 있다고 생각할지도 몰라요. 먼저 주제를 정하세요.Look at that Tesla!(저 테슬라 좀 봐!) 그런 다음 대명사를 사용하는 겁니다.
The red one is amazing.(저 빨간 거 진짜 멋지다.) 이 규칙은 단수와 복수 명사 모두에 적용됩니다. One은 단수용이고, Ones는 복수용이죠.this, that, which, the 같은 단어 뒤에 오기도 하죠. 마치 레고 조각 같아요.which가 가장 좋은 짝꿍입니다. Which one do you want?는 쇼핑할 때 쓸 수 있는 최고의 질문이죠.
Formation Pattern
phone.
one (단수). 예: The new one.
ones (복수). 예: The cheap ones.
the one이나 the ones를 사용하세요.
which one이나 which ones를 사용하세요.
this one / that one을 사용하세요.
another one을 사용하세요. DJ Khaled는 이 특정 패턴 하나로 성공적인 커리어를 만들었죠. 사실상 변장한 문법 선생님이나 다름없어요. 그냥 셀 수 없는 명사에는 절대 쓰지 마세요. 우유를 'a big one'이라고 할 수는 없으니까요. 우유 팩을 말하는 거라면 모르겠지만, 너무 깊게 들어가진 맙시다. 단순하게 생각하세요. 형용사가 먼저, 그다음에 대명사입니다. 한 팀인 거죠. 형용사는 설명하고, 대명사는 대표합니다. 둘이 합쳐지면 대화에서 승리하는 거예요.
When To Use It
ones와 캔버스로 된 ones를 비교하는 거죠. 배달 음식 앱에서도 아주 유용해요. Do you want the spicy burger or the mild one?(매운 버거 먹을래, 안 매운 거 먹을래?) 구체적으로 콕 집어 말할 때 사용합니다.My last project was a big one.(제 지난 프로젝트는 큰 건이었습니다.) 이렇게 말하면 간결하게 말할 수 있다는 걸 보여줍니다.Did you see my latest post?(내 최근 게시물 봤어?)
Which one?(어떤 거?) 이렇게 하면 왓츠앱 대화가 빠르게 이어지죠.one을 쓰세요.
Common Mistakes
one을 쓰는 겁니다. "I like this music. Let's listen to a better one«이라고 말하면 안 돼요. 음악은 셀 수 없거든요. 그냥 »better music«이나 »another song이라고 해야 합니다. 또 다른 실수는 복수형에 s를 빼먹는 거예요. I like those blue one«은 틀렸습니다. 대상이 복수라면 대명사도 복수여야 해요. »blue ones라고 말하세요. 어떤 사람들은I want greenthe를 빼먹기도 합니다. 구체적인 것을 말할 때는 보통the가 필요해요.
one«이라고 하면 타잔처럼 들립니다. »I want the green one이라고 하세요. 형용사 없이I want somesome,any,both뒤에 바로 쓰지 마세요.
ones«라고 하지 않습니다. 그냥 »I want some«이라고 하세요. 그리고 격식 있는 자리에서 사람에게 쓰지 마세요. »That one over there«라고 하면서 사람을 가리키면 좀 무례하게 들릴 수 있어요. »that person"이나 이름을 사용하세요. 형제자매라면 모를까. 그때는 아마 괜찮을 거예요. 우리 모두 그런 형제자매 '한 명(one)'쯤은 있잖아요, 그렇죠?Contrast With Similar Patterns
one과 it을 헷갈려 합니다. 이건 고전적인 싸움이죠. it은 구체적이고 유일한 대상을 말할 때 사용하세요.I have a car. I love it.(나 차 있어. 나 '그거' 정말 좋아해.) one은 어떤 것의 '종류'를 말할 때 사용하세요.I need a car. I want a fast one.(나 차가 필요해. 빠른 '거' 원해.) it은 구체적인 정체성이라고 생각하고, one은 카테고리의 일원이라고 생각하세요.ones와 them입니다. them은 이미 확인된 구체적인 대상들에 사용합니다. "I found my keys.them."(나 열쇠 찾았어. 나한테 '그것들' 있어.) ones는 어떤 종류의 열쇠인지 설명할 때 씁니다. I like the silver ones.(난 은색 '인 것들'이 좋아.) 이건 '그 물건'과 '그 물건의 버전'의 차이입니다.It은 지금 보고 있는 바로 그 영화고, One은 여러분이 평소 좋아하는 장르의 영화입니다. 섞어 쓰지 마세요.Quick FAQ
사람에게 one을 써도 되나요?
네, 하지만
the one I love나 the lucky one 같은 특정 문구에서만 쓰세요.
ones는 항상 복수인가요?
네. shoes, books, friends처럼 항상 복수 가산 명사에 사용하세요.
my나 your 뒤에 one을 써도 되나요?
보통은 안 됩니다. 우리는 mine이나 yours라고 해요.
my one이라고 하지 말고 mine이라고 하세요.
형용사가 없으면 어떡해요?
the one을 쓰면 됩니다. Which book?
The one on the table.
돈(money)에 써도 되나요?
아니요. 돈은 셀 수 없습니다. a coins나 notes라고는 할 수 있어도,
money ones라고는 못 해요.
격식 있는 글쓰기에서도 괜찮나요?
그럼요. 문법적으로 정확하고 업무용 이메일에서도 아주 흔하게 쓰입니다.

자주 묻는 질문 (8)
Yes! You can say 'the tall one' to refer to a person if it's clear you are talking about people. Example: 'Which boy is your son?' 'The tall one.'
In formal writing, it's better to just say 'these'. However, in daily conversation, 'these ones' and 'those ones' are very common and perfectly acceptable.
In standard English, we use possessive pronouns like `mine`, `yours`, or `his` instead of `my one`. However, if there is an adjective, you can use it: `my new one` is correct.
No. 'One' and 'ones' are only for countable nouns. For uncountable nouns like water, just repeat the noun or use 'some'.
`It` refers to a specific, unique object. `One` refers to a type of object or one choice among many.
Not always. You can use it after 'the', 'this', 'that', or 'which'. Example: 'I'll take the one on the left.'
Using 'one' to avoid repetition is neutral. Using 'one' to mean 'a person' (e.g., 'One must eat') is very formal.
Usually, we say 'a [adjective] one'. We rarely say 'a one' alone unless it's the number.
