An affix beside a repeated root does not automatically get repeated. The visible form depends on scope: Malay may copy a root and add an affix around the resulting unit, or it may copy an already derived word. Learning to see that hidden bracketing explains standard forms such as buku-bukunya, berjalan-jalan, and rumah-rumahan without memorizing them as punctuation accidents.
This page explains structure and spelling, not every meaning of ber-, ke-...-an, or -an. Those affix systems and the meanings of individual reduplicative patterns have dedicated pages.
The hyphen shows the repeated domain
In standard Rumi, full and changing-sound reduplication is hyphenated. An ordinary prefix is attached to the first written member, while a suffix or enclitic closes the second member when the affix has scope over the whole repeated unit. Spaces do not mark these internal boundaries.
| Step | Noun case | Result |
|---|---|---|
| Choose the base | buku “book” | buku |
| Copy the base | [buku + buku] | buku-buku |
| Add the clitic outside | [[buku + buku] + -nya] | buku-bukunya |
Buku-bukunya masih di dalam kotak kerana dia belum siap berpindah.
His books are still in the box because he has not finished moving. (neutral)
The clitic -nya attaches once to the complete reduplicated noun and identifies the whole set as associated with him, her, it, or the context. Buku-bukunya is not a shortened spelling of bukunya-bukunya. English puts a possessive before a plural noun; Malay instead puts the enclitic after the complete reduplicated form.
Saya sudah menyusun buku-buku di perpustakaannya.
I have arranged the books in his or her library. (neutral)
Here -nya attaches to perpustakaan, not to buku-buku. Position therefore matters: buku-bukunya means “his/her books,” whereas buku-buku di perpustakaannya means “the books in his/her library.”
Prefix outside a repeated verbal root
Many familiar verbs repeat the root while a prefix appears only once. The stepwise analysis of berjalan-jalan is:
| Step | Verb case | Result |
|---|---|---|
| Choose the root | jalan “walk; road” | jalan |
| Copy the root | [jalan + jalan] | jalan-jalan |
| Add the prefix outside | [ber- + [jalan + jalan]] | berjalan-jalan |
Selepas makan malam, kami berjalan-jalan di sekitar dataran bandar.
After dinner, we took a stroll around the town square. (neutral)
The standard form is berjalan-jalan, not berjalan-berjalan. Its meaning is also not mechanically “walk twice”: berjalan-jalan conventionally presents relaxed walking about (neutral). Other prefixed iterative forms can describe an activity continued without a sharp endpoint.
Dia mengetuk-ngetuk pintu itu, tetapi tiada siapa menjawab.
He kept knocking on the door, but nobody answered. (neutral)
In mengetuk-ngetuk, the second member represents the root after the prefixed first member. The spelling preserves the established morphological pattern; learners should not generate it by chopping letters off an arbitrary meN- verb. The iterative-verb guide treats which forms are conventional and what repeated activity means.
Kanak-kanak itu berlari-lari di halaman sementara menunggu ibu bapa mereka.
The children ran about in the yard while waiting for their parents. (neutral)
The single ber- has scope over the copied root lari-lari. Copying the visible prefix twice would mistake the written pieces for the underlying structure.
Circumfixes can enclose a copied adjective
Approximate colour and property words show both edges of the structure. With kemerah-merahan, the root merah is copied, then ke-...-an encloses that copied material.
| Step | Adjective case | Result |
|---|---|---|
| Choose the adjective | merah “red” | merah |
| Copy the adjective | [merah + merah] | merah-merah |
| Enclose it | [ke- + [merah + merah] + -an] | kemerah-merahan |
Langit di ufuk kelihatan kemerah-merahan sebelum matahari terbit.
The sky at the horizon looked reddish before sunrise. (neutral)
The circumfix is not copied on both halves. Semantically, kemerah-merahan means “somewhat reddish” or “resembling red,” not simply a plural form of merah. The construction is conventional and has lexical restrictions; it is not safe to wrap every English adjective in ke-...-an.
Gayanya kebarat-baratan, tetapi bahan yang digunakannya semuanya tempatan.
His style is rather Westernized, but all the materials he uses are local. (neutral; often carries speaker distance)
The same outer bracketing appears in kebarat-baratan. Because such forms can imply approximation, imitation, or criticism, morphology and stance must be learned together.
A suffix can derive a noun from a repeated base
The noun rumah-rumahan is built as [[rumah + rumah] + -an]. The suffix follows the second member because it applies to the repeated base as a whole.
| Step | Derived-noun case | Result |
|---|---|---|
| Choose the noun | rumah “house” | rumah |
| Copy the noun | [rumah + rumah] | rumah-rumah |
| Add the suffix | [[rumah + rumah] + -an] | rumah-rumahan |
Mereka membina rumah-rumahan daripada kotak untuk pameran sekolah.
They built model houses out of boxes for the school exhibition. (neutral)
The form does not mean ordinary plural “houses”; it refers to house-like models or play structures. This is why simply counting visible copies is insufficient. A derivational affix can change the category or meaning of the complete construction.
Adik membuat kapal-kapalan daripada kertas terpakai.
My younger sibling made toy boats from used paper. (neutral)
Forms of this type are partly lexical. -an does not guarantee “toy version” after every copied noun, so check established usage rather than inventing a new form whenever English uses model or toy.
Sometimes the whole derived word is copied
The “affix only once” observation is not a universal deletion rule. If the discourse pluralizes an already derived lexeme, that entire lexeme can be the copy domain. Perubahan-perubahan contains perubahan twice because each member is the derived noun “change”:
[perubahan] + [perubahan] → perubahan-perubahan
Perubahan-perubahan kecil itu akhirnya mempercepat proses permohonan.
Those small changes eventually sped up the application process. (formal)
Compare this with berjalan-jalan, where only jalan is copied inside a single ber- construction. The difference is grammatical, not stylistic: one repeats a complete derived noun, while the other builds one verb around a copied root.
Cadangan-cadangan tersebut akan dibincangkan dalam mesyuarat esok.
Those proposals will be discussed at tomorrow's meeting. (formal)
In cadangan-cadangan, the suffix -an belongs to the lexical noun cadangan, so the whole noun is repeated. There is no dependable visual shortcut. Identify the intended lexeme and consult a dictionary when the derivation is unfamiliar.
Clitics close the complete construction
Possessive -ku, -mu, and -nya attach orthographically to the preceding word. When they refer to a reduplicated noun, write them once after the second member.
| Bracketing | Standard form | Meaning |
|---|---|---|
| [[kawan + kawan] + -ku] | kawan-kawanku | my friends |
| [[gambar + gambar] + -mu] | gambar-gambarmu | your pictures |
| [[buku + buku] + -nya] | buku-bukunya | his/her books; the books concerned |
Kawan-kawanku sudah menunggu di lobi.
My friends are already waiting in the lobby. (neutral)
Gambar-gambarmu cantik, terutama yang diambil waktu senja.
Your pictures are beautiful, especially the ones taken at dusk. (neutral)
In formal edited prose, do not separate these clitics with a space and do not repeat them after both members. The enclitic has one host: the right edge of the complete reduplicated form.
Common Mistakes
1. Copying a prefix twice by sight
❌ Kami berjalan-berjalan di taman selepas makan.
Incorrect for the conventional verb—the prefix is not repeated.
✅ Kami berjalan-jalan di taman selepas makan.
We took a stroll in the park after eating. (neutral)
2. Putting a suffix on both copies
❌ Mereka membina rumahan-rumahan daripada kadbod.
Incorrect for model houses—the derivational suffix follows the complete copied base.
✅ Mereka membina rumah-rumahan daripada kadbod.
They built model houses out of cardboard. (neutral)
3. Repeating a possessive enclitic
❌ Bukunya-bukunya masih di dalam kotak.
Incorrect for ordinary ‘his books’—do not copy the possessed form with -nya on both members.
✅ Buku-bukunya masih di dalam kotak.
His books are still in the box. (neutral)
4. Applying the “one affix” pattern to a copied derived noun
❌ Perubah-perubahan itu akan dilaksanakan bulan depan.
Incorrect for ‘changes’—the two halves fail to copy the complete derived noun perubahan; perubah is a different lexeme.
✅ Perubahan-perubahan itu akan dilaksanakan bulan depan.
Those changes will be implemented next month. (formal)
Key Takeaways
Hyphenation makes reduplication visible, but bracketing determines what appears on each side. Berjalan-jalan and kemerah-merahan copy a root inside an outer affixal structure; rumah-rumahan adds -an to a copied base; buku-bukunya adds one enclitic at the right edge; and perubahan-perubahan copies a complete derived noun. Never copy or delete an affix by visual analogy alone.
