Indonesian Grammar

Indonesian uses the same 26-letter Latin alphabet as English, but spelling is much more regular. Read vowels as clear, short sounds; pronounce c like English ch, keep g hard as in go, and learn ng, ny, and sy as sound units. Indonesian has no tones, although natural word stress and sentence melody still matter.

Indonesian personal pronouns do not change with the verb or according to whether they mean “I” or “me”: saya bekerja means “I work,” while dia melihat saya means “he/she sees me.” The essential contrasts are social and inclusive: choose between polite saya and familiar aku, address people with suitable care, and distinguish kami (“we, not you”) from kita (“we, including you”).

Indonesian usually does not translate English am, is, and are with a separate word: Dia cantik means “She is beautiful,” and Saya guru means “I am a teacher.” Adalah is used mainly to connect one noun phrase to another in formal definitions or careful explanations. Do not put it automatically into every English sentence containing be.

Use ada when something exists, is present, or is available: Ada air means “There is water” or “Water is available.” Use punya when someone has or owns something: Saya punya air means “I have water.” Their basic negatives are tidak ada (“there is no…”) and tidak punya (“do not have…”).

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.

Indonesian adjectives usually come after the noun they describe: mobil baru means “a new car.” An adjective can also be the predicate (the part that says what the subject is like) without a word for “is” or “are”: Mobil itu baru means “That car is new.” Put sangat before an adjective or sekali after it to mean “very.”

Indonesian uses tidak before verbs and adjectives, bukan for nouns, pronouns, identity, and classification, belum for “not yet,” and jangan for “don’t.” The negative word normally comes directly before the word or phrase it applies to: Saya tidak mengerti (“I don’t understand”), but Saya bukan guru (“I’m not a teacher”).

Indonesian usually asks a question without changing the verb or adding an equivalent of English do, does, or did. Use rising intonation for an everyday yes/no question, add apakah for an explicit or more formal question, or ask for missing information with a question word such as apa “what,” siapa “who,” or di mana “where.”

Indonesian often repeats a word, usually with a hyphen, to express plurality, variety, repeated action, distribution, or emphasis: buku-buku “books,” anak-anak “children,” and perlahan-lahan “slowly.” However, reduplication is not an automatic equivalent of the English plural -s: after a number or a quantity word, the unrepeated noun is usually enough. Some repeated forms have their own dictionary meanings and need to be learned as vocabulary.

Indonesian numbers are built from a few regular pieces: dua belas is 12, dua puluh is 20, and dua puluh satu is 21. Ask Jam berapa sekarang? for the time and Berapa harganya? for a price. Use pukul before a specific clock time, and add pagi, siang, sore, or malam when the part of the day matters.

Use di for a location, ke for movement toward a destination, and dari for movement or origin away from a starting point: di rumah “at home,” ke sekolah “to school,” and dari Indonesia “from Indonesia.” Pada, dengan, untuk, and tanpa add meanings such as “at/on,” “with/by,” “for,” and “without.” These words normally come directly before a noun or noun phrase.

Indonesian normally puts the thing owned before its owner: buku saya means “my book,” literally “book I,” and rumah Ali means “Ali’s house.” The attached forms -ku, -mu, and -nya can mean “my,” “your,” and “his/her/its”: rumahnya is “his house,” “her house,” or “its home,” depending on context. Use punya or milik when possession itself is the focus, as in Ini punya siapa? (“Whose is this?”).

Indonesian ini means “this/these,” and itu means “that/those.” When they identify a noun, they normally come after it: buku ini (“this book”), orang itu (“that person”). For places, use di sini (“here”), di situ (“there, near you/at that place”), and di sana (“over there, farther away”).

Indonesian verbs do not change for person: saya makan means “I eat,” while dia makan means “he/she eats,” with the same verb makan. Start with a small set of everyday verbs—pergi, datang, makan, minum, tidur, buat, bicara, tulis, and baca—and add a subject, an object or place, and a time expression as needed.

Indonesian uses words such as hari ini (today), kemarin (yesterday), besok (tomorrow), and sekarang (now) to locate an event in time. The verb itself does not change for past, present, or future: context and time words usually do that work. Pagi, siang, sore, and malam divide the day into periods whose boundaries are practical rather than exact.

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.

Indonesian adverbs do not change form. Put sangat “very” and terlalu “too” before an adjective, masih “still” and selalu “always” before the state or action, and hanya/cuma “only” directly before what they limit. Juga “also/too” normally follows the person or thing being added: Saya juga suka means “I like it too.”

Indonesian everyday politeness relies on short, reusable expressions rather than one word that always corresponds to English “please.” Use selamat pagi to greet someone in the morning, maaf to apologize, tidak apa-apa to reassure them, silakan to invite them to do something, and sampai jumpa when you expect to meet again.

Indonesian often makes a command by using the verb without a subject: Duduk! means “Sit!” and Tunggu! means “Wait!” Add tolong for a request for help, silakan for an invitation or permission, mohon for a formal request, and jangan for “don’t.” The verb does not change according to whether you are speaking to one person or several people.

Indonesian normally puts suka “like,” mau/ingin “want,” perlu/butuh “need,” or benci “hate” directly before a noun or verb: Saya suka kopi “I like coffee”; Saya mau makan “I want to eat.” These words do not change with the subject, and tidak goes before them to make the basic negative: Saya tidak mau pergi “I do not want to go.”

English know covers several ideas that Indonesian usually keeps separate. Use tahu for facts or information, kenal for being acquainted with someone or familiar with something, mengerti or paham for understanding, and bisa for having the ability or knowing how to do something.

Use bisa for ability or possibility: Saya bisa berenang means “I can swim.” Use boleh for permission: Boleh saya masuk? means “May I come in?” The negative contrast is especially useful: tidak bisa means “cannot” or “not possible,” while tidak boleh means “must not” or “not allowed.”

Indonesian dates normally follow day number + month + year: 17 Agustus 1945. Add tanggal when you mean “the date” or “the ___th”: tanggal 17 Agustus. Unlike English, Indonesian uses ordinary numbers and adds no ending like -st, -nd, -rd, or -th.

Indonesian color words normally come after the noun: baju merah means “a red shirt.” A color can also describe the subject directly, without a word for “is”: Baju ini merah means “This shirt is red.” Use warna when you mean “color,” as in warna merah (“the color red”).

Indonesian commonly identifies siblings by relative age, not gender: kakak means an older sibling and adik a younger sibling. To say “my mother” or “their child,” put the family word first and the possessor second: ibu saya, anak mereka. Several family words also serve as respectful or friendly forms of address.

Use di for a location (“at/in”), ke for movement toward a place (“to”), and dari for movement or origin away from a place (“from”): di rumah, ke pasar, dari sekolah. These words are written separately from the place name. Indonesian often needs no equivalent of English “am/is/are” before a location: Saya di rumah means “I am at home.”

Indonesian spelling is quite regular: most letters have a stable sound, and every written vowel is normally pronounced. The main beginner challenges are the two sounds written e, the contrasts ng–ngg and ny–n+y, and combinations such as sy and kh. As a useful starting point, give a word gentle stress near the second-to-last syllable, but do not force the strong stress pattern common in English.

Indonesian commonly combines a time-of-day greeting with an address term: Selamat pagi, Pak (“Good morning, sir”) or Selamat sore, Bu (“Good afternoon, ma’am”). Pak/Bapak and Bu/Ibu are broadly useful respectful forms, while Mas and Mbak are friendlier terms for younger adults, especially in Java-influenced settings. Using an address term instead of a direct word for “you” often sounds natural and considerate.

Indonesian -nya attaches directly to the word before it. At beginner level, it most often means “his,” “her,” or “its” (rumahnya, “his/her house”), or points to a specific, already understood thing (bukunya, “the book”). It can also turn a quality into a noun-like idea: besar “big” → besarnya “the size/how big it is.”

Use di to describe a stationary location: di sini means “here,” di sana means “there,” and di bawah meja means “under the table.” Write di as a separate word in these expressions. For movement, replace it with ke (“to”) or dari (“from”): ke sana (“to there”), dari bawah meja (“from under the table”).

Indonesian me(N)- forms many active verbs, especially verbs that take an object: baca “read” becomes membaca “read something.” The N is a shorthand for a nasal sound that adjusts to the beginning of the root: tulis → menulis, baca → membaca, kirim → mengirim, and sapu → menyapu. Use the full prefixed form as your safe default in writing and formal speech.

Indonesian commonly makes a passive verb by attaching di- to a verb base: membaca “to read” becomes dibaca “to be read.” The person or thing affected by the action becomes the subject, while the agent (the person doing it) can be omitted or introduced with oleh “by.” The prefix is written as one word—dibaca—unlike the place preposition di, which is written separately: di rumah “at home.”

The Indonesian prefix ber- commonly forms verbs describing an activity, state, or characteristic of the subject: berjalan “walk,” bekerja “work,” and bernama “be named.” Many ber- verbs are intransitive (they do not direct their action at an object), but the prefix has several meanings and a few important spelling changes. Learn frequent forms as complete words rather than trying to translate ber- on its own.

Indonesian verbs do not change form to mark past, present, or future. Instead, time comes from context and words such as sudah “already,” sedang “in progress,” akan “will,” and besok “tomorrow”: Saya makan, Saya sudah makan, and Saya akan makan all keep the same verb, makan.

Use lebih + adjective + daripada for “more ... than,” and paling + adjective for “the most ...”: lebih cepat daripada (“faster than”), paling cepat (“the fastest”). For equality, use sama + adjective + dengan, while ter- can form some superlatives, especially familiar forms such as terbaik (“best”).

Use dari ... ke ... for a range or movement “from ... to ...,” di antara for a position “between/among,” and di sekitar for “in the area around.” Tentang introduces a topic (“about”), while menurut identifies the person or source behind an opinion (“according to”). These forms normally come before a noun phrase: menurut guru saya (“according to my teacher”).

Indonesian normally puts a quantity word before a noun: banyak orang (“many people”), sedikit air (“a little water”), and beberapa hari (“several days”). The same forms work without English-style distinctions such as “many” versus “much”: banyak covers both. Use semua for a complete group, setiap for every member considered one by one, and cukup for a sufficient amount.

Indonesian uses connectors such as ketika/waktu “when,” sebelum “before,” setelah/sesudah “after,” sambil/sementara “while,” begitu “as soon as,” and sejak “since” to place events in relation to one another. The time part can usually come first or second: Setelah makan, kami pergi and Kami pergi setelah makan both mean “After eating, we left.” Because Indonesian verbs do not change for tense, words such as sudah, sedang, and akan often supply details that English expresses through verb forms.

Use sendiri for “alone” or “without help,” and diri sendiri when an action points back to the person doing it: Saya melakukannya sendiri (“I did it myself”) and Dia menyalahkan diri sendiri (“He/she blames himself/herself”). Use saling before an action shared in both directions (“each other”), while bersama means that people do something together, not necessarily to one another.

The Indonesian prefix ter- has several common jobs: it can mark the highest degree (terbesar, “biggest”), an uncontrolled event (tertidur, “fell asleep”), or a state or possibility (terlihat, “visible/can be seen”). English uses different constructions for these meanings, so identify the meaning from the root and the context rather than assigning ter- one fixed translation.

The Indonesian prefix se- often carries an idea related to one: one item (sebuah rumah), one shared degree (sebesar ini, “as big as this”), or one group taken together (sekeluarga, “the whole family”). It also appears in frequency expressions such as sehari sekali (“once a day”). However, common words such as setiap and seluruh are best learned as whole words, not treated as models for freely creating new forms.

The suffixes -kan and -i often turn a root into a verb that takes an object, but they organize the event differently. -kan commonly makes or causes something to happen, does something for someone, or directs a moving thing; -i commonly treats a person, place, or surface as the target of an action. These are useful tendencies, not a rule that lets you predict every verb, so learn frequent derived verbs together with their object patterns.

Indonesian usually introduces a condition with kalau or jika, both meaning “if”: Kalau hujan, saya tidak pergi (“If it rains, I won’t go”). Verbs do not change form to distinguish “if I have,” “if I had,” and “if I had had”; context and words such as akan, sudah, and seandainya show whether a situation is real, imagined, or contrary to fact. Maka (“then”) may introduce the result, but it is often omitted in ordinary conversation.

Indonesian normally places yang after a person or thing to introduce information that identifies or describes it: orang yang tinggal di sini means “the person who lives here.” The same linker works where English uses who, which, or that, but Indonesian keeps yang even when English can leave its relative word out: buku yang saya baca, “the book (that) I read.”

Indonesian pe(N)- forms many nouns for a person who performs an action or, less often, a tool that performs it: tulis “write” → penulis “writer,” baca “read” → pembaca “reader,” and sapu “sweep” → penyapu “sweeper; broom.” The (N) shows that the prefix has several forms—pe-, pem-, pen-, peny-, peng-, and sometimes penge-—chosen largely according to the root’s first sound.

Indonesian adds -an to many base words to form a noun (a word for a person, thing, place, or idea): makan “eat” becomes makanan “food,” and tulis “write” becomes tulisan “something written; writing.” The resulting meaning is often the thing produced, used, or associated with the base, but many -an words are established vocabulary and cannot always be predicted exactly.

Indonesian commonly strengthens an adjective with sekali after it (indah sekali, “very beautiful”) or benar-benar before it (benar-benar indah, “really beautiful”). For a more expressive “How …!”, use betapa or alangkah, often in the pattern betapa/alangkah + adjective + -nya: Betapa indahnya! or Alangkah indahnya!

Use untuk before a noun or a compact verb phrase: untuk ujian (“for the exam”), untuk membeli rumah (“to buy a house”). Use agar or supaya before a fuller clause meaning “so that,” especially when its subject is stated: Saya bicara pelan agar semua orang mengerti (“I speak slowly so that everyone understands”). Biar is the more conversational choice and can also mean “let”: Biar saya bantu (“Let me help”).

To present an event and then say what follows from it, Indonesian commonly uses jadi in conversation, sehingga within one closely connected sentence, and oleh karena itu or akibatnya between sentences in more careful writing. Maka also means “then/therefore,” especially in formal reasoning and paired patterns such as jika ..., maka .... The basic order is cause → result.

Indonesian verbs do not change form to show past, present, or future, so a clear timeline often comes from context and time expressions. Use pertama to open a sequence, kemudian, lalu, or selanjutnya to move it forward, and akhirnya to introduce the ending or final outcome. Combine these words with markers such as kemarin (“yesterday”), setelah itu (“after that”), and tiba-tiba (“suddenly”) to turn separate actions into a connected story.

Indonesian uses meskipun or walaupun before a fact that does not prevent the main event: Meskipun hujan, kami tetap pergi means “Although it was raining, we still went.” Sekalipun can make the concession stronger or more hypothetical, while bagaimanapun usually comments on the whole situation as “nevertheless” or “in any case.” Tetap (“still, nevertheless”) often reinforces the unexpected result.

Use semoga or mudah-mudahan for an outcome that you genuinely hope is possible: Semoga kamu cepat sembuh (“I hope you recover soon”). Use andai, andaikan, or seandainya to imagine a different reality, often with the force of “if only” or “suppose”: Andai saya punya lebih banyak waktu (“If only I had more time”). Indonesian verbs do not change into a special wish form; context and time words show whether a wish concerns the present, future, or past.

Indonesian uses several different tools where English often relies on “is,” “means,” or “is called.” Ask X itu apa? to find out what something is, use artinya for meaning, yaitu to identify or specify, and disebut or dinamakan to give a name. Choosing among them depends mainly on whether you are asking, interpreting, specifying, or naming.

Indonesian word order is flexible, but adverbs still have preferred homes. Time expressions commonly frame the sentence at the beginning or end; frequency words usually sit before the verb; manner follows the action, often after its object; and degree words stay beside the adjective or adverb they modify. Moving an adverb can shift the emphasis or its scope, so “grammatically possible” does not always mean “equally natural.”

Indonesian commonly puts the affected person or thing first and marks the verb with di-: Polisi menangkap dia becomes Dia ditangkap polisi (“He was arrested by the police”). The agent—the person or thing performing the action—may be omitted, placed after the verb, or introduced with oleh. In everyday speech, kena often presents an unpleasant event as something that happened to someone, while terkena means “be affected, exposed, or hit by.”

The Indonesian Type 2 passive puts the patient (the person or thing affected) first, followed by a pronoun agent and a bare verb: Buku itu saya baca (“I read that book” or, literally, “That book was read by me”). Markers such as sudah, akan, and belum normally come before the agent: Buku itu sudah saya baca. Do not add the active prefix meN- or the passive prefix di- to the verb in this pattern.

Indonesian reports statements with bahwa “that” and yes/no questions with apakah “whether/if”: Dia mengatakan bahwa dia lelah and Dia bertanya apakah saya akan datang. Unlike English, Indonesian verbs do not change tense when moved into indirect speech. Pronouns, place words, and time expressions may still change when the speaker’s point of view changes.

Indonesian conjunctions show how ideas relate: dan “and,” atau “or,” tetapi “but,” karena “because,” oleh karena itu “therefore,” and meskipun “although.” The key B2 skill is choosing a connector that matches both the logic and the register: conversational tapi and jadi often correspond to more formal tetapi/namun and oleh karena itu. Indonesian verbs do not change when these connectors are used.

Indonesian goes beyond basic kalau (“if”) by marking different relationships between a condition and its result: asalkan sets a sufficient condition, kecuali (kalau/jika) introduces an exception, meskipun presents a fact or possibility that does not change the result, and kalau tidak gives the alternative consequence. Indonesian verbs do not change into special conditional forms, so time, likelihood, and whether a situation is real or imagined come from context, time expressions, and words such as akan, sudah, masih, and tetap.

Indonesian correlative constructions use two matching connectors to present two ideas as a balanced pair. The four central patterns are semakin...semakin (“the more...the more”), baik...maupun (“both...and”), bukan hanya...tetapi juga (“not only...but also”), and entah...entah (“whether...or”). Keep the material after each half grammatically parallel whenever possible.

Indonesian links clauses (sentence parts that express separate ideas) with connectors such as karena “because,” jika/kalau “if,” and walaupun/meskipun “although.” Full pairs such as jika...maka and bukan hanya...tetapi juga make the relationship especially explicit, but not every apparent pair must be completed: in concise formal prose, Karena hujan, saya terlambat is often preferable to Karena hujan, maka saya terlambat.

Indonesian expresses different kinds of causation with verbs that show how much control or pressure is involved. Membuat causes a result, memaksa forces someone, meminta requests, memerintahkan orders, and mengusulkan proposes an idea or course of action. The complement after each verb is not identical: choosing between a noun phrase, a bare verb, untuk, and agar is part of using these constructions naturally.

Indonesian particles such as -lah, -kah, sih, dong, and kok do not usually change the basic facts in a sentence; they show the speaker's attitude toward those facts. -lah can emphasize or soften a directive, -kah marks a question, sih adds informal emphasis or contrast, dong makes an appeal or urges cooperation, and kok signals surprise or a clash with expectations.

Indonesian written connectors tell readers how one statement relates to another: pertama opens a sequence, selain itu adds a point, sebaliknya presents a reverse contrast, dengan kata lain restates an idea, and singkatnya summarizes it. At the beginning of a sentence, these connectors are normally followed by a comma: Selain itu, biaya operasional dapat dikurangi.

Indonesian reported speech does not normally shift verbs into a special past form. Instead, choose a reporting verb and connect the report with bahwa for statements, apakah or a question word for indirect questions, and patterns such as meminta/menyuruh + person + untuk + verb for reported requests and commands. Time words and pronouns may still change when the speaker, viewpoint, or situation changes.

Formal Indonesian (bahasa Indonesia formal or ragam formal) is the standard register used in official correspondence, reports, public announcements, news, and much academic or professional writing. It favors complete affixes, standard vocabulary, explicit links between ideas, and carefully chosen forms of address. Formality is not simply a matter of inserting Anda: purpose, audience, sentence structure, and document conventions all matter.

An Indonesian circumfix is a pair of affixes placed around a base: ke-...-an, pe(N)-...-an, or per-...-an. These patterns often create nouns: bahagia “happy” becomes kebahagiaan “happiness,” while belajar “to study” becomes pembelajaran “the process of learning.” The meaning is systematic enough to guide you, but many finished words have become established vocabulary and cannot be predicted from the base alone.

Administrative Indonesian (bahasa administrasi) is the official register used in surat dinas (official letters), decisions, regulations, institutional notices, and government forms. It favors standard formulas, fully affixed words, passive or impersonal structures, noun-heavy phrases, and exact references to documents, dates, articles, and obligations. The aim is not decorative formality but wording that is consistent, traceable, and difficult to misread.

Indonesian can place a topic first—what the sentence is about—and then comment on it: Buku itu, sudah saya baca (“That book, I’ve already read”). To identify one element as the important contrast, Indonesian often uses -lah or a yang-cleft: Masalah inilah yang penting (“This problem is what matters”). These patterns change emphasis and information structure, not simply the factual content.

Literary Indonesian (bahasa sastra) is not a separate grammar but a flexible register used to create imagery, rhythm, emotional force, and multiple layers of meaning. It often combines carefully chosen vocabulary with compressed phrases, parallel structures, repetition, figurative comparison, and word orders that would feel marked in ordinary conversation.

Indonesian news uses a compact, formal register built around clear attribution and information order. Headlines often omit context that appears in the lead, while reports favor di- passives, formal reporting verbs, and source markers such as menurut “according to” and berdasarkan “based on.” Reported statements do not normally undergo the tense changes familiar from English; time is shown by context and words such as telah, sedang, and akan.

Formal Indonesian often puts the event, result, or information first and leaves the person responsible unstated. The main tools are an agentless di- passive, as in Keputusan ini telah disetujui, and impersonal frames such as Dapat dikatakan bahwa ... and Perlu diketahui bahwa .... These patterns are especially common in reports, academic prose, official notices, and news writing.

Indonesian has absorbed vocabulary from Sanskrit, Arabic, Dutch, Portuguese, and English, adapting most words to Indonesian spelling and pronunciation: Dutch kantoor became kantor, while English system became sistem. Once established, a borrowed root can behave like other Indonesian roots and take native affixes: akses → mengakses → diakses. A word's origin can offer clues about meaning and register, but present-day usage—not etymology alone—determines which form is natural.

Bahasa gaul is flexible, highly informal Indonesian shaped by everyday speech, Jakarta usage, youth culture, regional languages, and borrowed words. Common signals include gue/lu for “I/you,” nggak for “not,” shortened forms such as udah and gimana, informal verbs such as nonton and bantuin, and particles such as dong, deh, sih, and kok. These forms are useful for understanding conversation, but they are not interchangeable with standard Indonesian in every place or relationship.

Indonesian peribahasa are established sayings that compress advice, criticism, or a general observation into memorable imagery. Idioms are fixed expressions whose intended meaning goes beyond the literal words. To use either well, learn the complete phrase together with its meaning, tone, usual context, and grammatical role—not as a set of words to translate one by one.

Indonesian online writing combines ordinary informal Indonesian with shortened spellings such as yg for yang, slang blends such as baper, playful typography, and English words fitted into Indonesian sentences. There is no single fixed “internet grammar”: forms vary by platform, community, age, and tone, so advanced learners need to read the social signal as well as the literal words.

Academic Indonesian presents a claim, supports it with evidence, and marks how strongly the evidence justifies the conclusion. It favors complete standard forms, explicit links between ideas, careful source attribution, and impersonal or passive wording where the researcher is less important than the procedure or result. A strong text is not merely “formal”: it is precise about who claims what, on what basis, and with what limitations.

Indonesian has a national standard, but everyday Indonesian varies by region through pronunciation, vocabulary, address terms, particles, and patterns borrowed from local languages. Forms such as mas, mbak, teh, bli, uda, and sampun can identify a social relationship or regional setting; the advanced skill is to understand those signals without assuming that every local speaker uses them in the same way.

Indonesian groups figures of speech under majas, while gaya bahasa refers more broadly to a writer’s or speaker’s style. Five central devices are perumpamaan (simile), metafora (metaphor), personifikasi (personification), hiperbola (hyperbole), and ironi (irony). At C2, the key skill is to interpret the intended effect—comparison, vividness, emotional intensity, or criticism—rather than merely attach a label.

Classical Malay survives in Indonesian through pronouns, courtly vocabulary, narrative connectors, and recurring hikayat storytelling patterns. Words such as hamba, baginda, alkisah, and clause-initial maka can create an old, courtly, or legendary voice, but they are not a ready-made substitute for ordinary modern Indonesian. At C2, the essential skill is to recognise the voice, interpret it in context, and reproduce it only when the genre calls for it.
