Basic Verb Structure in Indonesian

In Brief

Indonesian verbs do not change to match the subject or to form a tense: saya makan, dia makan, and mereka makan all use the same verb, makan. Indonesian usually follows subject–verb–object order, while context and words such as sedang “in progress,” sudah “already/completed,” and akan “will” locate an action in time.

Overview

Basic Indonesian verb structure is refreshingly regular. English changes eat to eats, ate, or eaten and often adds an auxiliary verb (a helping verb) such as is, has, or will. Indonesian normally leaves the verb unchanged. The subject—who or what performs the action—does not alter its form, and neither does singular or plural number.

This is one of the first sentence patterns learned at A1 because it lets you communicate with useful verbs immediately. Once you know makan “eat,” for example, you can talk about yourself, another person, or a group without learning a conjugation table. You can also add a time expression or an aspect marker (a word showing whether an action is ongoing, complete, or expected) without rebuilding the verb.

The beginner rule is simple: put the subject first, then the verb, then the object if there is one. An object is the person or thing affected by the action: in Saya minum kopi, kopi is what is drunk. Later, you will meet prefixes, passive voice, and differences between formal and conversational verb forms. Those additions matter, but they do not create person-based conjugations.

How It Works

The basic pattern: subject + verb + object

Many Indonesian statements use S–V–O order:

Part	Indonesian	Meaning
Subject	Saya	I
Verb	minum	drink
Object	kopi	coffee

Together: Saya minum kopi. “I drink coffee.”

Not every verb needs an object. An intransitive verb (a verb whose action does not pass to an object) can make a complete sentence with only a subject and verb:

• Mereka tidur. — “They sleep.”
• Rina datang. — “Rina comes/is coming.”
• Kami pergi. — “We leave/are leaving.”

Indonesian does not require an equivalent of English do/does in an ordinary statement. Nor should you insert adalah before a normal verb: Saya makan, not Saya adalah makan.

One verb form for every person and number

The verb stays the same regardless of the subject:

Subject	Form with makan	English
saya / aku	saya makan / aku makan	I eat
kamu / Anda	kamu makan / Anda makan	you eat
dia	dia makan	he/she eats
kami / kita	kami makan / kita makan	we eat
kalian	kalian makan	you all eat
mereka	mereka makan	they eat

English speakers should pay special attention to the third person. There is no Indonesian -s corresponding to he eats. Dia makan is correct.

Bare verbs and time from context

A bare verb—one without a time or aspect marker—does not automatically mean “simple present.” Its time comes from the situation or from an expression such as setiap hari “every day,” kemarin “yesterday,” or besok “tomorrow.”

Indonesian	Natural English interpretation
Saya bekerja setiap hari.	I work every day.
Saya bekerja kemarin.	I worked yesterday.
Saya bekerja besok.	I work tomorrow / I’m working tomorrow.

This is why there is no single Indonesian ending for English -ed. If the time is already clear, a bare verb may be enough.

Putting time expressions in the sentence

A time expression commonly appears at the beginning or end:

• Besok kami berangkat. — “Tomorrow we leave.”
• Kami berangkat besok. — “We leave tomorrow.”
• Kemarin dia datang. — “She/he came yesterday.”

Placing time first makes the time frame prominent and gives the listener useful context before the action. Both positions above are normal.

Using sedang, sudah, and akan

These words normally come directly before the verb or verb phrase:

Marker	Core idea	Pattern	Example
sedang	action in progress	subject + sedang + verb	Saya sedang membaca.
sudah	action completed or state already reached	subject + sudah + verb	Saya sudah membaca.
akan	future, intention, or expectation	subject + akan + verb	Saya akan membaca.

Sedang is close to English be + -ing, but Indonesian does not add a form of “be”: Dia sedang tidur means “He/She is sleeping.” In conversation, the context can make sedang unnecessary, so Dia tidur may also describe what someone is doing.

Sudah often corresponds to already, have/has, or a simple past form, depending on context. Its central message is completion or a reached state, not a mechanical copy of the English present perfect. Saya sudah makan can naturally mean “I have eaten,” “I already ate,” or, in response to an offer, “I’ve eaten already.”

Akan places the event after the current reference point. It can translate English will or be going to, but a clear future expression often makes it optional: both Saya akan pergi besok and Saya pergi besok can mean “I’m going tomorrow.” Adding akan makes the future orientation more explicit.

More than one word before the verb

Other common words can occur before a verb without changing its form:

• Saya mau makan. — “I want to eat.”
• Dia bisa berenang. — “He/She can swim.”
• Kami harus pergi. — “We must leave.”
• Mereka belum datang. — “They haven’t arrived yet.”

English often uses to between two verbs, as in want to eat. Indonesian normally does not: mau makan, not mau untuk makan in this basic meaning.

Examples in Context

Indonesian	English	Note
Saya makan nasi setiap pagi.	I eat rice every morning.	Habit; the verb is bare.
Dia makan di kantor.	He/She eats at the office.	Makan does not gain an ending with dia.
Mereka minum teh.	They drink tea.	Plural subject, unchanged verb.
Adik tidur sekarang.	My younger sibling is sleeping now.	Present time comes from sekarang.
Saya sedang makan.	I am eating.	Action currently in progress.
Kami sedang belajar bahasa Indonesia.	We are studying Indonesian.	Sedang stands before the verb.
Saya sudah makan.	I have eaten.	The meal is complete.
Busnya sudah datang.	The bus has arrived.	A completed arrival/current result.
Mereka belum datang.	They have not arrived yet.	Belum means “not yet.”
Saya akan makan setelah rapat.	I will eat after the meeting.	Explicit future with akan.
Besok dia pergi ke Bandung.	Tomorrow he/she is going to Bandung.	Future understood without akan.
Kemarin kami menonton film.	Yesterday we watched a film.	Past time comes from kemarin.
Kamu bisa memasak?	Can you cook?	No English-style do is needed.
Saya mau membeli tiket.	I want to buy a ticket.	Two verbs occur without to.
Setiap sore Budi membaca koran.	Budi reads the newspaper every afternoon.	S–V–O with a habitual time phrase.

Common Mistakes

Adding an English third-person ending

• Wrong: Dia makans nasi.
• Right: Dia makan nasi.
• Why: Indonesian verbs do not take English -s. The same form makan follows saya, dia, and mereka.

Changing the verb to create a past tense

• Wrong: Kemarin saya “makaned” di rumah.
• Right: Kemarin saya makan di rumah.
• Why: Kemarin already establishes past time. Indonesian has no regular tense ending equivalent to English -ed.

Translating the progressive word for word

• Wrong: Saya adalah sedang makan.
• Right: Saya sedang makan.
• Why: Indonesian does not use adalah as the helping verb in the progressive. Put sedang directly before the action.

Using English-style do in a statement or question

• Wrong: Saya melakukan makan nasi setiap hari.
• Right: Saya makan nasi setiap hari.
• Why: Melakukan means “perform/do” as a full verb; it is not an empty helping verb like English do. Indonesian questions also do not need it: Kamu makan nasi? can mean “Do you eat rice?”

Treating sudah as a universal past marker

• Wrong: Kemarin saya sudah tinggal di Jakarta selama dua tahun when you only mean “I lived in Jakarta for two years.”
• Right: Dulu saya tinggal di Jakarta selama dua tahun.
• Why: Sudah highlights completion, prior occurrence, or an already-reached state. Past time alone does not require it. Choose it for the meaning, not simply because English uses a past form.

Putting the marker after the verb

• Wrong: Saya makan sedang.
• Right: Saya sedang makan.
• Why: Basic aspect and time markers such as sedang, sudah, and akan normally precede the verb phrase.

Usage Notes

In everyday speech, Indonesian speakers frequently omit information that is obvious from the conversation. Sudah makan? literally has no stated subject, but naturally asks “Have you eaten?” Sudah by itself can answer “Yes, already/I have.” This is not a different conjugation; it is context doing work that English often assigns to pronouns and auxiliaries.

Sedang is clear and neutral, especially when emphasizing that something is in progress. Informal speech also uses lagi after the verb: Aku makan lagi can mean “I’m eating” in colloquial context, but it can also mean “I eat again.” To avoid ambiguity as a beginner, use sedang makan for “am eating” and learn conversational lagi through context.

Pronoun choice changes register even though the verb does not. Saya is neutral or polite, aku is personal and informal, Anda is formal or impersonal in many settings, and subjects may be titles or kinship terms. Compare Saya akan kirim besok with Aku kirim besok: the verb remains unchanged while the relationship conveyed by the pronoun shifts.

Beyond the Basics / Advanced Use

You do not need to master the following details at A1, but they explain why Indonesian verbs may not always look as “bare” as makan or tidur.

Affixes change meaning and voice, not person or tense

Indonesian builds many verbs with affixes—pieces added before or after a base. For example, baca is related to membaca “read,” and tulis to menulis “write.” The meN- family commonly forms active verbs; ber- occurs in verbs such as berjalan “walk” and bekerja “work.” Suffixes such as -kan and -i can affect what participants a verb takes or how its meaning is directed.

These forms are word-building patterns, not conjugation by subject:

• Saya membaca buku. — “I read a book.”
• Dia membaca buku. — “He/She reads a book.”
• Mereka membaca buku. — “They read books/a book.”

Conversational Indonesian sometimes drops an active prefix where formal writing keeps it: baca may replace membaca, and beli may replace membeli. Do not assume every prefix is always optional; learn the standard dictionary form and notice colloquial alternatives separately.

Indonesian voice can change word order

Indonesian makes frequent use of passive and object-focused structures. Saya membaca buku itu means “I read that book,” while Buku itu dibaca oleh saya means “That book is read by me.” With pronoun agents, another common pattern is Buku itu saya baca—literally arranged as “That book, I read.” This departure from basic S–V–O is systematic, not free word order.

Aspect markers express viewpoints, not exact English tenses

More advanced reading brings finer distinctions:

• telah also marks completion and is more common in formal writing than everyday conversation;
• masih means “still,” as in Dia masih bekerja “He/She is still working”;
• baru saja means “just,” as in Mereka baru saja tiba “They have just arrived”;
• combinations are possible, such as sudah tidak bekerja “no longer works/is no longer working.”

The scope and order of these words matter. Rather than assigning each one a fixed English tense, ask what stage of the event the speaker wants to highlight.

Practice Tips

1. Run one verb through subjects, not endings. Say saya makan, kamu makan, dia makan, kami makan, mereka makan. This trains you to keep the verb stable while changing who acts.
2. Build a four-line time set. For each new verb, make a bare sentence and versions with sedang, sudah, and akan: Saya belajar; Saya sedang belajar; Saya sudah belajar; Saya akan belajar. Then translate each by meaning rather than word for word.
3. Anchor bare verbs with real time phrases. Write three sentences using setiap hari, kemarin, and besok. Notice that the verb stays identical even when the natural English translation changes tense.
