Korean conjunctions become much easier when you stop looking for one Korean word to replace each English connector. English uses familiar words such as “and,” “but,” “or,” and “by the way,” yet Korean may choose a separate adverb, an ending attached to a predicate, a particle attached to a noun, or a conversation marker depending on what is being connected. Learning that difference turns connector choice from memorization into a repeatable decision.
A beginner may learn 그리고 geurigo and and assume that every English “and” should become 그리고. The same learner may memorize 하지만 hajiman but, 아니면 animyeon or, and 그런데 geureonde by the way / but in the same way.
That vocabulary is useful, but it does not yet explain how Korean actually connects ideas. A noun may need a particle. Two predicates may need a connective ending. Two completed statements may be joined by an independent connector. A conversation may change direction with a discourse marker that has no perfect one-word translation in English.
The most reliable beginner strategy is therefore to look at the relationship first. Are you adding information? Contrasting two facts? Offering alternatives? Or changing the direction of a conversation? Then look at the size of the units being connected. Are they nouns, predicates, complete statements, or conversational turns?
The central rule: do not translate the English connector first. Identify what Korean needs to connect, then choose the grammar that fits that relationship.
How Korean Connectors Work
The English word “conjunction” can make beginners imagine a list of standalone vocabulary words. Korean connection works more broadly. Some connectors stand independently. Others attach directly to the word before them.
A connector can work between complete ideas
Consider two complete statements:
저는 한국어를 공부해요. 그리고 매일 일기를 써요.
jeoneun hangugeoreul gongbuhaeyo. geurigo maeil ilgireul sseoyo.
I study Korean. And I write a diary every day.
The first sentence is already complete. The second adds another piece of information. 그리고 works independently between those ideas.
A connector can be part of the first predicate
Korean often keeps related actions or descriptions inside one sentence by attaching an ending to the first predicate.
아침을 먹고 학교에 가요.
achimeul meokgo hakgyoe gayo.
I eat breakfast and go to school.
한국어는 어렵지만 재미있어요.
hangugeoneun eoryeopjiman jaemiisseoyo.
Korean is difficult, but interesting.
In 먹고 meokgo, the ending -고 -go links the first action to the next one. In 어렵지만 eoryeopjiman, -지만 -jiman creates contrast while keeping both sides inside one sentence.
A connector can attach directly to a noun
Korean particles can also connect noun-level choices or lists.
사과하고 바나나를 샀어요.
sagwahago bananareul sasseoyo.
I bought apples and bananas.
커피나 차를 마셔요.
keopina chareul masyeoyo.
I drink coffee or tea.
In the first sentence, 하고 hago joins nouns with an “and” relationship. In the second, 나 na joins noun alternatives with an “or” relationship.
A connector can manage the conversation itself
Some expressions do more than connect grammatical units. They tell the listener how the conversation is moving.
다음 주에 서울에 가요. 그런데 어디에 묵을 거예요?
daeum jue Seoure gayo. geureonde eodie mugeul geoyeyo?
You are going to Seoul next week. By the way, where are you going to stay?
The second question remains related to the Seoul trip but moves the conversation in a new direction. This is why Korean connectors are easier to understand when grammar and conversation are learned together.
Korean connectors operate at several levels. Some stand between statements, some attach to predicates, some attach to nouns, and some guide the direction of conversation. Before choosing a form, identify the level at which the connection is happening.
How to Say “And” in Korean
English “and” can connect almost anything: nouns, actions, descriptions, clauses, and entire sentences. Korean makes more of those differences visible.
Three beginner forms are especially useful: 그리고 geurigo and, -고 -go and / and then, and 하고 hago and / with.
그리고 adds another idea
그리고 is an independent connector. It can join words, phrases, clauses, and sentences, but beginners notice it most easily when one complete statement is followed by another.
오늘은 날씨가 좋아요. 그리고 시간이 많아요.
oneureun nalssiga joayo. geurigo sigani manayo.
The weather is nice today. And I have plenty of time.
The first statement is complete. The speaker simply adds another fact.
-고 connects predicates inside a sentence
When two actions or descriptions naturally belong in one sentence, Korean often attaches -고 to the first predicate.
저녁을 먹고 산책해요.
jeonyeogeul meokgo sanchaekaeyo.
I eat dinner and take a walk.
이 방은 크고 조용해요.
i bangeun keugo joyonghaeyo.
This room is big and quiet.
The first predicate stays grammatically connected to what follows instead of ending as a complete polite sentence.
하고 can connect nouns in everyday Korean
빵하고 우유를 샀어요.
ppanghago uyureul sasseoyo.
I bought bread and milk.
Here, 하고 follows the noun 빵 ppang bread and connects it to another noun.
The visible letters 하고 can hide two different structures
Compare 사과하고 sagwahago and 공부하고 gongbuhago.
사과 sagwa apple is a noun, so 하고 is the noun-connecting particle.
공부하다 gongbuhada to study becomes 공부하 + -고. The visible 하고 comes from a 하다 predicate plus the connective ending -고.
This distinction is more important than memorizing three English definitions because it teaches you how Korean words are built.
The easiest way to stop guessing is to compare the three forms inside matching sentence patterns and see exactly what each one connects.
The full contrast between sentence-level 그리고, predicate ending -고, and noun particle 하고 is explained in And in Korean: 그리고, -고, 하고 Made Easy.
Once the grammatical level becomes visible, choosing “and” is much more predictable than translating from English first.
For a beginner, remember the basic map: 그리고 often adds another idea, -고 connects predicates, and 하고 commonly connects nouns. The shared English translation “and” does not make the three forms grammatically identical.
How to Say “But” in Korean
English “but” can signal direct opposition, an unexpected result, a limitation, a reservation, or a contrast between two descriptions. Korean again gives you more than one way to organize that relationship.
Three beginner forms are especially useful: 하지만 hajiman but / however, 그런데 geureonde but / however, and -지만 -jiman but / although.
하지만 introduces a clear contrasting statement
한국어는 어려워요. 하지만 정말 재미있어요.
hangugeoneun eoryeowoyo. hajiman jeongmal jaemiisseoyo.
Korean is difficult. But it is really interesting.
The first statement ends normally. Then 하지만 clearly marks the turn toward contrasting information.
-지만 puts the contrast inside one sentence
한국어는 어렵지만 재미있어요.
hangugeoneun eoryeopjiman jaemiisseoyo.
Korean is difficult, but interesting.
가고 싶지만 시간이 없어요.
gago sipjiman sigani eopseoyo.
I want to go, but I do not have time.
The National Institute of Korean Language describes -지만 as a connective ending that recognizes the preceding content and adds something opposite or different. This explains why it works naturally when both sides of the contrast belong together inside one sentence.
그런데 can introduce contrast with a conversational turn
그 카페가 좋아요. 그런데 주말에는 사람이 너무 많아요.
geu kapega joayo. geureonde jumareneun sarami neomu manayo.
That café is nice. But it is too crowded on weekends.
The second statement introduces a problem that changes how the first statement is evaluated. This is a genuine contrast use of 그런데.
Contrast is often about expectation, not dictionary opposites
“Pretty” and “expensive” are not opposites, yet the following contrast is completely natural:
이 가방은 예쁘지만 너무 비싸요.
i gabangeun yeppeujiman neomu bissayo.
This bag is pretty, but it is too expensive.
The second fact changes the practical conclusion created by the first. Korean contrast expressions frequently work with this kind of expectation, not just literal opposites such as “big” and “small.”
하지만 can also appear inside a longer form for a different reason
A learner may see 공부하지만 gongbuhajiman and assume that the independent connector 하지만 has been inserted after 공부. The actual structure is different.
공부하다 gongbuhada to study becomes 공부하 + -지만. The letters 하지만 are visible because the stem ends in 하 and the connective ending begins with 지만.
The important difference is not which English translation appears in a dictionary. The real difference is whether the contrast begins as a new statement, redirects the discussion, or remains inside one sentence.
Those structures and their most common beginner traps are compared closely in But in Korean: 하지만, 그런데, -지만 Made Easy.
Seeing the same situation rewritten with all three forms is especially useful for learning the distinction.
Use 하지만 for a clearly introduced contrasting statement, -지만 when the contrast stays inside one sentence, and recognize that 그런데 can introduce a contrasting complication while also shaping conversational direction.
How to Say “Or” in Korean
“Or” seems simple in English, but alternatives can also exist at different grammatical levels. You might choose between two nouns, two full actions, two dates, or two possible outcomes.
Three useful beginner forms are 아니면 animyeon or / if not / otherwise, 또는 ttoneun or, and -(이)나 -(i)na or.
아니면 is useful when another full option follows
오늘 갈까요? 아니면 내일 갈까요?
oneul galkkayo? animyeon naeil galkkayo?
Shall we go today? Or shall we go tomorrow?
여기서 먹을까요? 아니면 포장할까요?
yeogiseo meogeulkkayo? animyeon pojanghalkkayo?
Shall we eat here? Or shall we get it to go?
Each alternative can stand as its own question. This makes 아니면 easy to use when the two choices are larger than simple nouns.
또는 independently connects alternatives
이메일 또는 전화로 문의해 주세요.
imeil ttoneun jeonhwaro munuihae juseyo.
Please contact us by email or phone.
월요일 또는 수요일에 방문할 수 있어요.
woryoil ttoneun suyoire bangmunhal su isseoyo.
You can visit on Monday or Wednesday.
The alternatives are presented side by side with an independent connector. This construction is especially easy to encounter in compact information, instructions, explanations, and written material, although 또는 is not restricted to writing.
-(이)나 attaches directly to nouns
For noun alternatives, Korean can attach a particle to the first noun.
Use 이나 ina.
책이나 잡지
chaegina japji
a book or a magazine
Use 나 na.
커피나 차
keopina cha
coffee or tea
Do not translate every 이나 or 나 as “or”
This particle has several functions. The National Institute of Korean Language lists a choice use in which two or more things are placed on equal footing and one may be selected, but it also lists other meanings.
커피나 차를 마셔요.
keopina chareul masyeoyo.
I drink coffee or tea.
세 시간이나 기다렸어요.
se siganina gidaryeosseoyo.
I waited for as long as three hours.
The second sentence does not contain an alternative at all. The particle emphasizes the unexpectedly large amount of time.
Predicate alternatives often need different grammar
If two actions are being connected rather than two nouns, Korean commonly uses another form such as -거나 -geona or.
책을 읽거나 영화를 봐요.
chaegeul ilgeona yeonghwareul bwayo.
I read a book or watch a movie.
You do not need to master every “or” structure at once. Recognizing that noun alternatives and predicate alternatives are grammatically different is already an important step.
The fastest way to choose correctly is to separate full alternatives from noun-level alternatives and then check whether the sentence is conversational or compactly informational.
The 받침 rule, the additional meanings of 이나/나, and the difference between 아니면 and 또는 are broken down with matching examples in Or in Korean: 아니면, 또는, -(이)나 Made Easy.
That distinction also prevents the common mistake of attaching noun grammar to verbs.
Think of 아니면 when another full alternative follows, 또는 as an independent alternative connector, and -(이)나 for noun-level alternatives. Always check the surrounding sentence before assuming that 이나 or 나 means “or.”
How to Say “By the Way” in Korean
“By the way” works differently from ordinary “and,” “but,” and “or” because it often manages the direction of a conversation rather than connecting two equal grammatical units.
Three useful expressions to recognize are 그런데 geureonde by the way / but / well, 근데 geunde by the way / but / well, and 그런데 말이에요 geureonde marieyo by the way / the thing is.
그런데 can redirect a conversation while keeping a connection
The National Institute of Korean Language gives 그런데 a specific “by the way” function: it changes the direction of a story while relating what follows to the preceding content.
다음 주에 제주도에 가요. 그런데 어디에서 묵을 거예요?
daeum jue Jejudoe gayo. geureonde eodieseo mugeul geoyeyo?
You are going to Jeju next week. By the way, where are you going to stay?
The second question moves in a new direction, but it is still connected to the trip.
근데 is the shortened form of 그런데
근데 내일 몇 시에 만나요?
geunde naeil myeot sie mannayo?
By the way, what time are we meeting tomorrow?
근데 is not a completely different connector. It is officially listed as the shortened form of 그런데 and can share its topic-shifting, contrast, and conversation-opening functions.
그런데 말이에요 can prepare the listener for a new point
그런데 말이에요, 하나 물어봐도 돼요?
geureonde marieyo, hana mureobwado dwaeyo?
By the way, may I ask you something?
그런데 말이에요, 제가 내일 조금 늦을 것 같아요.
geureonde marieyo, jega naeil jogeum neujeul geot gatayo.
The thing is, I think I may be a little late tomorrow.
The second English translation shows why discourse markers should not be memorized through a single English equivalent. In that context, “the thing is” captures the conversational function more naturally than literal “by the way.”
The same 그런데 can also mean “but”
새 가방 샀어요? 그런데 어디에서 샀어요?
sae gabang sasseoyo? geureonde eodieseo sasseoyo?
You bought a new bag? By the way, where did you buy it?
그 가방은 예뻐요. 그런데 너무 비싸요.
geu gabangeun yeppeoyo. geureonde neomu bissayo.
That bag is pretty. But it is too expensive.
The word itself has not changed. The relationship between the sentences has.
Context decides the translation, and the easiest way to hear the difference is to compare topic shifts, contrasts, shortened 근데, and attention-getting 말이에요 in real conversational patterns.
Those discourse functions are explored more closely in By the Way in Korean: 그런데, 근데, 그런데 말이에요.
Learning the conversational function also makes listening practice easier because many natural uses do not map neatly onto one English word.
그런데 can redirect a conversation while keeping it connected to what came before, 근데 is its shortened form, and 그런데 말이에요 can prepare the listener for a new point. Context separates the “by the way” function from the “but” function.
How to Choose the Right Korean Connector
The four English ideas above become much easier when they are reduced to a small set of decisions. Instead of asking, “What is the Korean word for this English conjunction?” ask what relationship you are trying to create.
Step 1: Identify the relationship between the ideas
Think about “and” structures such as 그리고, -고, or noun-connecting 하고.
Think about 하지만, 그런데, or -지만.
Think about 아니면, 또는, -(이)나, or a predicate connector such as -거나.
Think about discourse uses of 그런데, 근데, or an attention-guiding expression such as 그런데 말이에요.
Step 2: Identify what is being connected
Noun-level relationships often use particles: 사과하고 바나나 sagwahago banana apples and bananas, or 커피나 차 keopina cha coffee or tea.
Verb and adjective connections commonly use endings: 먹고 가요 meokgo gayo eat and go, or 비싸지만 좋아요 bissajiman joayo it is expensive, but I like it.
Independent words can introduce the relationship after the first statement has ended: 그리고, 하지만, 아니면, and 그런데 can all appear in this broader environment for different meanings.
When the issue is not simply grammar inside one sentence but how one topic leads to another, discourse markers such as 그런데 and 근데 become especially important.
Step 3: Decide whether one sentence or two sounds more natural
Beginners often create many short sentences because independent connectors are easy to remember.
아침을 먹어요. 그리고 학교에 가요.
achimeul meogeoyo. geurigo hakgyoe gayo.
I eat breakfast. And I go to school.
아침을 먹고 학교에 가요.
achimeul meokgo hakgyoe gayo.
I eat breakfast and go to school.
Both structures can communicate the idea. The second packages the related actions more compactly. Recognizing this choice is one of the first steps from textbook-like Korean toward more flexible sentence building.
Step 4: Do not confuse spelling with grammatical identity
Korean often creates identical-looking letter sequences through different grammatical structures.
친구하고 동생
chinguhago dongsaeng
a friend and a younger sibling
Here, 하고 is a particle following the noun 친구.
공부하고 쉬어요.
gongbuhago swieoyo.
I study and rest.
Here, 공부하다 becomes 공부하 + -고.
가고 싶어요. 하지만 바빠요.
gago sipeoyo. hajiman bappayo.
I want to go. But I am busy.
하지만 independently introduces the contrast.
매일 공부하지만 아직 어려워요.
maeil gongbuhajiman ajik eoryeowoyo.
I study every day, but it is still difficult.
공부하지만 is 공부하 + -지만.
Checking the dictionary form before analyzing the connector prevents many beginner errors.
Step 5: Treat English translation as the final check, not the first step
English translation is still useful. The problem appears when it controls the Korean sentence too early.
For example, 그런데 can become “but” in one context and “by the way” in another. 이나/나 can mean “or” when connecting alternatives but can express emphasis or a fallback choice elsewhere. -고 may sound like “and” or “and then” depending on the relationship between actions.
The Korean function should therefore come first. The natural English wording comes afterward.
A practical self-check for new sentences
English and Korean divide grammatical relationships differently. A form that translates as “and,” “but,” “or,” or “by the way” in one sentence may need a different English translation in another. Learn the Korean job of the expression first.
Connector choice becomes systematic when you make two decisions in order: What relationship am I expressing? and What grammatical units am I connecting? Those questions are more reliable than memorizing English-to-Korean pairs.
Frequently Asked Questions About Korean Conjunctions
Useful beginner connectors include 그리고 geurigo and, 하지만 hajiman but, 아니면 animyeon or / otherwise, and 그런데 geureonde but / by the way. Beginners should also learn attached forms such as -고, -지만, and -(이)나 because Korean does not express every connection with a separate word.
No. 그리고 can connect ideas, while -고 -go commonly connects predicates inside one sentence and 하고 hago can connect nouns. The best form depends on what is being joined.
하지만 hajiman is an independent word that can introduce a contrasting statement. -지만 -jiman is a connective ending attached directly to a predicate, as in 어렵지만 재미있어요 eoryeopjiman jaemiisseoyo It is difficult, but interesting.
아니면 can introduce another full alternative, such as 오늘 갈까요? 아니면 내일 갈까요? oneul galkkayo? animyeon naeil galkkayo? Shall we go today? Or tomorrow?. -(이)나 attaches directly to nouns, as in 커피나 차 keopina cha coffee or tea.
It can mean either depending on context. When the following statement opposes or limits the previous one, English “but” may fit. When the speaker changes the direction of the conversation while keeping a connection to the earlier topic, “by the way” may be more natural.
근데 geunde is the shortened form of 그런데 geureonde. It shares the same major topic-shifting and contrast functions and is especially common in conversation.
Korean frequently uses connective endings rather than separate conjunction words. Forms such as -고 and -지만 become part of the first predicate and show how it relates to the next part of the sentence. This is one reason direct word-for-word translation from English often causes confusion.
Take one simple situation and express it in more than one structure. Compare two short sentences with one connected sentence, noun-level choices with full alternatives, and contrast uses of 그런데 with topic-shifting uses. Rewriting the same message helps you learn the grammatical relationship rather than memorize isolated translations.
Korean conjunctions are easiest to learn as a system of relationships rather than a vocabulary list. Addition, contrast, alternatives, and topic shifts each interact with sentence structure in different ways.
Korean Conjunctions: What to Learn First
A strong beginner foundation starts with one simple idea: Korean does not have to copy the grammatical shape of English connectors.
For addition, learn to distinguish 그리고, -고, and 하고. For contrast, separate 하지만 from predicate ending -지만, while remembering that 그런데 can also introduce a contrasting turn.
For alternatives, recognize the difference between a full alternative introduced with 아니면, an independent 또는, and noun-level -(이)나. For conversation flow, learn how 그런데, 근데, and expressions such as 그런데 말이에요 guide listener attention.
If sentence endings are still unfamiliar, beginning with “and” is often easiest because the difference between nouns, predicates, and completed statements becomes visible immediately. If sentence building already feels comfortable but conversations still sound abrupt, the topic-shifting expressions deserve more attention. Learners who repeatedly translate directly from English will often benefit most from comparing “but” and “or” structures side by side.
The aim is not to memorize every connector before speaking. It is to recognize the question that comes before the connector choice: What am I connecting, and what relationship do I want the listener to understand?
Write four or five simple sentences about your day. Add one idea with 그리고 or -고, create one contrast with 하지만 or -지만, offer one alternative with 아니면 or -(이)나, and finish with a related question introduced by 그런데 or 근데.
Keep the vocabulary easy. The useful practice is choosing the connection, not making the sentence complicated. If this explanation helped clarify Korean sentence flow, save it for review and share it with another learner who is building the same foundation.
