Indonesian uses four broad communicative sentence types: statements, questions, commands, and exclamations. Their internal words often change less than English learners expect. Intonation, question words, particles, punctuation, and context frequently identify the sentence type without person or tense inflection on the verb.
This overview introduces the central patterns and the major kinds of predicate. It leaves advanced clause linking, complete question paradigms, and the detailed pragmatic meanings of individual particles to their dedicated pages.
Four communicative sentence types
Declaratives: giving information
A declarative presents information as a statement. Its neutral written punctuation is a period, and its spoken intonation normally falls at the end.
Nadia bekerja di perpustakaan kampus.
Nadia works at the university library.
Kereta terakhir berangkat pukul sebelas malam.
The last train leaves at eleven at night.
Kamar sebelah masih kosong.
The room next door is still empty.
Notice that the third sentence contains no written equivalent of English is. Kosong “empty” is already a complete predicate.
Interrogatives: requesting information
A yes–no question can have exactly the same word sequence as a statement in everyday speech. Rising or questioning intonation signals its function, and a question mark records that function in writing.
Nadia bekerja di perpustakaan kampus?
Does Nadia work at the university library?
Kamu sudah sarapan?
Have you had breakfast? (informal)
Apakah pertemuannya dimulai pukul sembilan tepat?
Does the meeting start at exactly nine? (formal)
Apakah makes a yes–no question explicit and is common in careful speech and formal writing. Everyday questions often omit it. A question word replaces the missing information instead:
Rapatnya dimulai pukul berapa?
What time does the meeting start?
Siapa yang menjaga meja depan hari ini?
Who is staffing the front desk today?
English normally needs do, does, or did for many questions. Indonesian does not insert an auxiliary merely to turn a clause into a question.
Imperatives: directing someone
An imperative tells or asks an addressee to act. The understood subject is usually “you,” so it need not be written. A plain verb can be direct; tolong makes a request more courteous, and jangan introduces a prohibition.
Tutup jendelanya sebelum keluar.
Close the window before going out.
Tolong kirim alamat lengkapnya lewat pesan.
Please send the full address by message.
Jangan menaruh tas di lorong.
Do not put bags in the aisle.
The missing subject is licensed by the command situation. Indonesian does not need to add kamu simply because English grammar describes an implied “you.” An overt kamu is possible for contrast or a firmer directive, while a name or title can be used as direct address when clarity or politeness requires it.
Bu Rina, silakan duduk di kursi depan.
Ms. Rina, please sit in the front seat.
Exclamatives: expressing a strong reaction
An exclamative presents information with surprise, admiration, frustration, or another strong attitude. Intonation and an exclamation mark are important; expressions such as wah, betapa, or a degree phrase may also make the reaction explicit.
Wah, ramai sekali pasar malam ini!
Wow, the night market is really crowded!
Betapa cepatnya waktu berlalu!
How quickly time passes! (formal)
Panas sekali siang ini!
It's so hot this afternoon!
Betapa is elevated and more frequent in writing or public speech. Wah and a degree phrase are natural in everyday conversation. The exclamation mark should reflect a genuine exclamative force, not decorate every enthusiastic sentence.
One proposition across four clause types
The following set keeps the basic proposition “Dita brings that folder” while changing what the speaker is doing with it:
Dita membawa map itu ke ruang rapat.
Dita is bringing that folder to the meeting room. (declarative)
Dita membawa map itu ke ruang rapat?
Is Dita bringing that folder to the meeting room? (interrogative)
Dita, bawa map itu ke ruang rapat.
Dita, bring that folder to the meeting room. (imperative)
Wah, Dita benar-benar membawa map itu ke ruang rapat!
Wow, Dita really did bring that folder to the meeting room! (exclamative)
The Indonesian verb does not acquire a question, command, or exclamation conjugation. Word order, address, intonation, and small framing words indicate the speaker's purpose.
What can serve as a predicate?
English learners often associate “sentence” with a conjugated verb. Indonesian clauses can instead be completed by a noun phrase, adjective, prepositional phrase, or verb phrase.
| Predicate category | Basic pattern | Typical meaning |
|---|---|---|
| noun phrase | Sari mahasiswa baru. | identity or classification |
| adjective phrase | Kamarnya sangat terang. | property or state |
| prepositional phrase | Kuncinya di laci. | location or relation |
| verb phrase | Sari membuka jendela. | event, action, or process |
Pak Damar kepala sekolah kami.
Mr. Damar is our principal.
Kursi ini terlalu rendah untuk meja itu.
This chair is too low for that table.
Payung saya di dekat pintu masuk.
My umbrella is near the entrance.
Pak Damar sedang berbicara dengan orang tua murid.
Mr. Damar is speaking with a student's parents.
The first three need no copula in neutral conversation. Adalah can have a role in formal nominal definitions, but it is not a general Indonesian translation of English be. See predicate types.
Simple and complex clauses
A simple sentence contains one main clause with one central predicate. It may still have a long subject, objects, and time or place expressions.
Teman sekamar saya memasak mi di dapur bersama dua tetangga tadi malam.
My roommate cooked noodles in the kitchen with two neighbors last night.
Despite its length, this is one clause centered on memasak. A complex sentence contains more than one clause, each with its own predicate, joined or embedded in a larger structure.
Teman sekamar saya memasak mi karena semua warung sudah tutup.
My roommate cooked noodles because all the food stalls had closed.
Saya mencuci piring, lalu Rafi membersihkan meja.
I washed the dishes, and then Rafi cleaned the table.
The second clauses have their own predicates: sudah tutup and membersihkan. At A1, the useful distinction is simply one central predication versus more than one. Advanced relationships between clauses are covered separately.
Subjects and pronouns need not be repeated
Once a subject is clear, Indonesian often omits it in a following clause. Commands likewise normally omit the addressee.
Mira masuk ke kamar, meletakkan tas, lalu langsung tidur.
Mira went into the room, put down her bag, and went straight to sleep.
Sudah selesai?
Are you finished? / Is it finished? (informal, context-dependent)
English usually requires an overt subject in a complete finite sentence. Indonesian lets context supply one when the reference is obvious. This is not permission to omit every subject: introduce or repeat it whenever the listener could reasonably misunderstand.
Punctuation and written form
Capitalize the first word of a sentence and proper names. Use a period for a statement, a question mark for a direct question, and an exclamation mark for a genuine command or exclamation when the force warrants it.
Besok kami bertemu di Stasiun Gambir.
Tomorrow we are meeting at Gambir Station.
Besok kita bertemu di mana?
Where are we meeting tomorrow?
Particles are separate words unless they are clitics. Thus apakah is one word, because -kah is attached, while sudah makan remains two words. Do not invent a written copula or pronoun to make the Indonesian line resemble English.
Common Mistakes
Adding English do to a question
❌ Do kamu tinggal dekat sini?
Incorrect — Indonesian yes–no questions do not use English do-support.
✅ Kamu tinggal dekat sini?
Do you live near here? (informal)
Inserting adalah before an adjective
❌ Cuacanya adalah dingin pagi ini.
Incorrect neutral predicate — dingin needs no copula.
✅ Cuacanya dingin pagi ini.
The weather is cold this morning.
Using tidak for a prohibition
❌ Tidak membuka pintu darurat!
Incorrect intended prohibition — tidak forms ordinary negation, not a negative command.
✅ Jangan membuka pintu darurat!
Do not open the emergency door!
Using statement punctuation for a direct question
❌ Kamu pulang jam berapa.
Incorrect punctuation — this is a direct question.
✅ Kamu pulang jam berapa?
What time are you going home?
Treating sentence length as clause count
❌ Kalimat panjang pasti memiliki dua klausa.
Incorrect analysis — length does not determine how many clauses a sentence has.
✅ Panjang atau pendeknya kalimat tidak menentukan jumlah klausa.
A sentence's length does not determine its number of clauses.
Key Takeaways
- Declaratives state, interrogatives ask, imperatives direct, and exclamatives express a strong reaction.
- Indonesian often marks sentence type through intonation, particles, framing words, and punctuation rather than verb inflection.
- Nouns, adjectives, prepositional phrases, and verbs can all form predicates.
- A simple clause has one central predication; a complex sentence contains more than one clause.
- Do not import English auxiliaries, obligatory copulas, or repeated pronouns into Indonesian.
