Basic Conjunctions in Indonesian

In Brief

Use dan for “and,” atau for “or,” tapi/tetapi for “but,” karena for “because,” jadi for “so,” and lalu for “then.” These words can connect items or ideas without changing their form. For a beginner, the main task is choosing the relationship you mean: addition, choice, contrast, reason, result, or sequence.

Overview

A conjunction is a linking word: it joins words, phrases, or clauses (groups of words that express an idea). Indonesian basic conjunctions are especially learner-friendly because they do not change for person, number, or tense. Dan remains dan whether you are talking about one person or many, and karena remains karena whether the reason is in the past or present.

These links appear everywhere in everyday Indonesian. You use them to order food, explain a decision, contrast two facts, and tell events in order. They are introduced at A1 because even a small set lets you move beyond isolated statements: Saya capek (“I’m tired”) and Saya istirahat (“I’m resting”) become Saya capek, jadi saya istirahat (“I’m tired, so I’m resting”).

English and Indonesian often make the same broad distinctions, but the two languages do not always build a complete sentence in the same way. Indonesian frequently leaves out information that is already clear, including the subject (“I,” “you,” and so on). That is why natural examples such as Mau pergi tapi sibuk may literally look like “want to go but busy.” Context supplies the person involved.

How It Works

The six core links

Link	Core meaning	Relationship	Basic pattern
dan	and	addition	A dan B
atau	or	choice or alternative	A atau B
tapi / tetapi	but	contrast	idea A, tapi/tetapi idea B
karena	because	reason or cause	result karena reason
jadi	so, therefore	result or conclusion	cause, jadi result
lalu	then	next event in a sequence	event A, lalu event B

The parts on either side can be single items or larger ideas. Compare kopi dan teh (“coffee and tea”) with Saya minum kopi dan dia minum teh (“I drink coffee and she/he drinks tea”).

Dan: adding information

Use dan to join people, things, qualities, actions, or clauses:

• saya dan kamu — me and you
• murah dan enak — cheap and delicious
• makan dan minum — eat and drink
• Saya memasak dan dia mencuci piring. — I cook and she/he washes the dishes.

When two actions have the same subject, you normally do not need to repeat it: Saya mandi dan sarapan means “I shower and have breakfast.” Dan simply adds the second action; it does not by itself emphasize which action happened first.

Atau: offering alternatives

Use atau between alternatives:

• kopi atau teh — coffee or tea
• hari ini atau besok — today or tomorrow
• Mau makan di sini atau di rumah? — Do you want to eat here or at home?

Like English “or,” atau can introduce a real choice or uncertainty: Dia di kantor atau di rumah means the speaker is considering those two possibilities. Context tells you whether only one choice is possible or whether several options may be accepted.

Tapi and tetapi: showing contrast

Both tapi and tetapi mean “but.” They introduce information that contrasts with, limits, or is unexpected after the first idea:

• Mau pergi, tapi sibuk. — I want to go, but I’m busy.
• Rumahnya kecil tetapi nyaman. — The house is small but comfortable.

Tapi is very common in conversation and informal writing. Tetapi is the fuller form and is more at home in careful or formal writing, though it is not restricted to formal contexts. Their grammar is the same at this level.

If the same subject applies to both parts, Indonesian often omits it in the second part—or in both parts when context is clear. Saya mau datang, tapi tidak bisa naturally means “I want to come, but I can’t.”

Karena: giving the reason

Karena introduces a reason. A straightforward pattern is:

result + karena + reason

Saya di rumah karena hujan. — “I’m at home because it’s raining.”

The reason can also come first:

karena + reason, result

Karena hujan, saya di rumah. — “Because it’s raining, I’m at home.”

When the karena clause comes first, a comma helps show where the reason ends. A clause is simply a part of the sentence built around an event or state; here, karena hujan gives the cause.

Jadi: stating the result

Jadi points in the opposite logical direction from karena. First comes the situation or cause, and then its result:

cause + jadi + result

Hujan, jadi saya di rumah. — “It’s raining, so I’m at home.”

This contrast is worth memorizing:

Focus	Indonesian	English
reason	Saya istirahat karena capek.	I’m resting because I’m tired.
result	Saya capek, jadi saya istirahat.	I’m tired, so I’m resting.

Jadi has other meanings outside this basic pattern, including “to become” and conversational “so…”. The relationship between ideas, not the word in isolation, tells you which meaning is intended.

Lalu: moving to the next event

Use lalu when one event follows another:

Saya mandi, lalu sarapan. — “I shower, then have breakfast.”

Unlike dan, lalu presents a sequence. Compare:

• Dia membuka pintu dan menyalakan lampu. — She/he opens the door and turns on the light. (two actions)
• Dia membuka pintu, lalu menyalakan lampu. — She/he opens the door, then turns on the light. (explicit order)

Do not use lalu merely because two facts appear in the same sentence. It is best when the second action is the next step in time or in a process.

Common Mistakes

Reversing karena and jadi

• Wrong: Saya capek, karena saya istirahat. (when you mean that tiredness causes the rest)
• Right: Saya capek, jadi saya istirahat.
• Why: Karena introduces the cause; jadi introduces the result. Ask whether the next part answers “why?” or “what happened as a result?”

Using dan when order matters

• Less clear: Saya membayar dan pulang.
• Clearer for sequence: Saya membayar, lalu pulang.
• Why: Dan adds an action, but lalu explicitly says that going home happened next.

Treating tapi as incorrect Indonesian

• Unnecessarily corrected: Saya suka, tetapi mahal.
• Natural in conversation: Saya suka, tapi mahal.
• Why: Tapi is a standard everyday form, not a learner error. Choose tetapi when the setting calls for more formal or careful style.

Repeating every subject as English does

• Grammatical but heavy in context: Saya bangun, lalu saya mandi, lalu saya sarapan.
• More natural: Saya bangun, lalu mandi, lalu sarapan.
• Why: When the subject stays the same and is obvious, Indonesian commonly leaves it unspoken. Repetition is possible when clarity or emphasis requires it.

Combining reason and result too heavily in formal writing

• Conversational: Karena hujan, jadi kami di rumah.
• More concise: Karena hujan, kami di rumah. / Hujan, jadi kami di rumah.
• Why: The paired form is common in speech, but careful formal prose often marks the relationship only once. Beginners can build cleaner sentences by choosing either karena or jadi.

Usage Notes

Spoken and written choices

For ordinary conversation, tapi and jadi are extremely useful. Tetapi often sounds more deliberate and is frequent in edited prose. In formal writing, punctuation and explicit subjects may also be used more consistently to keep long sentences clear. This is a difference of register—the level of formality appropriate to a situation—not a change in the basic meaning.

In casual speech, Indonesian speakers may also use terus where “then” or “and then” fits. Lalu remains a safe, widely usable choice and is preferable while learning the core system. You do not need a new conjunction for every English use of “then”: when “then” means “in that case” rather than “next in time,” jadi or a different expression may fit better.

Commas and pauses

A comma is helpful between two full ideas before tapi, jadi, or lalu, especially when each side is long. It is usually unnecessary in a short pair such as kopi dan teh or murah tapi enak. When a reason beginning with karena comes first, use a comma after that opening reason in careful writing: Karena sakit, dia tidak bekerja.

English equivalents are guides, not formulas

English often requires a visible subject and a finite verb (a verb form tied to a subject and time), while Indonesian can rely more on context. Capek jadi istirahat is understandable informal Indonesian even though its natural English translation needs “I’m”: “I’m tired, so I’m resting.” Translate the complete idea, not each word one by one.

Beyond the Basics

You do not need to master these points at A1, but they explain forms you will encounter later.

Jadi is multifunctional. As a verb, it can mean “become,” “happen,” “be completed,” or “go ahead,” depending on context: Dia jadi guru means “She/He became a teacher,” while Rapatnya jadi? asks whether the meeting is going ahead. As a discourse marker (a word organizing the conversation), sentence-initial Jadi, ... can mean “So, ...” when drawing a conclusion or returning to a point.

Lalu can organize a narrative, not only connect two nearby actions. A speaker can use it to move the story forward: Lalu, apa yang terjadi? means “Then, what happened?” In more developed writing, repeated lalu may sound monotonous, so learners later add a wider range of temporal connectors.

Longer and more formal texts make finer distinctions among consequences and transitions. Maka, oleh karena itu, akibatnya, and sehingga overlap partly with basic jadi, but their sentence patterns and tone are not identical. Similarly, written discourse uses connectors such as selain itu (“besides/in addition”) and sebaliknya (“conversely/on the other hand”). Learn the six basic links first; they provide the logical foundation for those later choices.

Indonesian also has paired structures for relationships that English may express with pairs such as “both…and” or “either…or.” Those structures deserve separate study. Do not assume that adding a second basic conjunction will automatically reproduce the English pattern.

Practice Tips

1. Build six versions from two ideas. Start with pairs such as hujan (“it is raining”) and di rumah (“at home”). Connect them with karena and jadi in the correct direction, then invent examples for addition, choice, contrast, and sequence.
2. Tell a three-step routine. Say what you do in the morning using lalu: Saya bangun, lalu mandi, lalu sarapan. On a second attempt, replace one lalu with dan and notice how the emphasis on sequence changes.
3. Listen for omitted subjects. In short Indonesian videos or conversations, note examples after tapi, jadi, and lalu where the speaker does not repeat saya, dia, or mereka. Repeat the sentence as a complete chunk instead of translating word by word.
