Productive Malay prefixes and suffixes normally form one written word with their base. Write membaca, not mem baca or mem-baca, and diperbaiki, not di perbaiki. A boundary hyphen becomes necessary when a capitalized, all-capital, or mixed-case base would otherwise create an awkward graphic collision.
Saya membaca laporan itu sebelum mesyuarat bermula.
I read the report before the meeting began.
Jalan yang rosak itu sudah diperbaiki.
The damaged road has been repaired.
This page explains the written boundary. The meanings, voice functions, and sound alternations of individual affixes belong to their morphology pages.
Ordinary prefixes are written solidly
Attach a productive prefix directly to an ordinary lowercase base: ber- + jalan → berjalan, ter- + buka → terbuka, di- + baca → dibaca, and peN- + tulis → penulis. The spelling presents the derived form as one orthographic word.
Tingkap bilik mesyuarat masih terbuka.
The meeting-room window is still open.
Surat itu dibaca oleh pengurus pagi tadi.
The letter was read by the manager this morning.
Penulis itu akan bertemu para pembaca di Shah Alam.
The writer will meet readers in Shah Alam.
The prefix di- must not be confused with the preposition di. The passive prefix attaches to a verb (dibaca, “is read”), whereas the location preposition stands apart (di pejabat, “at the office”). See writing di and ke for the full contrast.
Laporan itu dibaca di pejabat.
The report was read at the office.
The first di- is attached because it builds the passive verb dibaca. The second di is separate because it introduces a location.
Sound alternation does not create a written gap
With the meN- and peN- families, the visible prefix may change and a root-initial consonant may disappear. MeN- + baca gives membaca; meN- + tulis gives menulis. These changes are morphological and phonological, but the result is still one written word.
Dia menulis nombor telefon itu di belakang resit.
She wrote the telephone number on the back of the receipt.
Kami sedang membaca cadangan yang baharu diterima.
We are reading the proposal that has just been received.
Do not recover an abstract boundary with a space or hyphen. Malay orthography records the conventional surface word, not a classroom segmentation such as mem-baca. A linguistic analysis may display mem- + baca in a table, but running prose uses membaca.
Ordinary suffixes are also solid
Attach suffixes such as -kan, -i, and -an directly to their base. When prefixes and suffixes occur together, the complete derived word remains solid: baik + di-per-...-i → diperbaiki, makan + -an → makanan, selesai + meN-...-kan → menyelesaikan.
Juruteknik itu berjaya menyelesaikan masalah rangkaian.
The technician managed to solve the network problem.
Makanan untuk tetamu sudah dihidangkan.
The food for the guests has been served.
The spelling diperbaiki is especially useful to inspect: di-, per-, and -i all belong to the word, so none receives a space. English expresses many comparable meanings with separate auxiliaries or prepositions; that does not make Malay affixes separate words.
Some bases are compounds. Their spelling depends on which affixes are present and on the established status of the compound, so do not generalize from a simple base to every multiword expression. Compounds treats separate, solid, and circumfixed patterns.
Use a hyphen before a capitalized base
If a bound form is attached to a proper name beginning with a capital, place a hyphen at the graphic boundary: se-Malaysia, pro-Malaysia, and anti-Amerika. The hyphen prevents the reader from mistaking the capitalized base for the interior of an ordinary lowercase word.
Kempen itu dijalankan secara serentak se-Malaysia.
The campaign was carried out simultaneously throughout Malaysia.
Compare ordinary serantau, written solidly because rantau is a lowercase common base, with se-Malaysia, where the proper name keeps its capital.
Syarikat itu mahu memperluas perkhidmatannya ke seluruh rantau.
The company wants to expand its services throughout the region.
The hyphen is not decoration and does not mark every prefix. It responds to the unusual visual boundary between a lowercase affix and a base whose capitalization must be preserved.
Affixes and clitics on all-capital forms
An all-capital initialism also takes a boundary hyphen when a lowercase bound element follows it: ATM-nya, KDN-nya, DBP-lah. This keeps the capitals readable and shows that the lowercase material is not another initial.
ATM-nya terletak berhampiran pintu masuk utama.
Its ATM is located near the main entrance.
Strictly speaking, -nya and -lah are clitics or particles rather than derivational suffixes, but the same graphic principle applies: capitals interrupt the normal solid lowercase word. Their grammar is explained on the clitics page.
DBP-lah badan yang menerbitkan pedoman itu.
It is DBP that publishes that guide. (emphatic)
Do not insert a space: ATM nya separates material that is grammatically bound. Do not erase the boundary either: ATMnya visually absorbs nya into the initialism.
Mixed-case names and branded forms
Mixed-case names such as MyKad preserve their official internal capitalization. Add a bound prefix or following clitic with a hyphen: ber-MyKad, MyKad-nya. The hyphen lets the branded base remain visually intact.
Peserta ber-MyKad diminta menggunakan lorong sebelah kanan.
Participants with a MyKad are asked to use the lane on the right. (administrative)
MyKad-nya tertinggal di kaunter pendaftaran.
His or her MyKad was left at the registration counter.
Ber-MyKad may sound administrative because the mixed-case proper form itself belongs to institutional usage. In ordinary conversation, speakers may choose a fuller phrase such as mempunyai MyKad. The spelling rule remains the same whenever the prefixed form is used.
Do not import unrelated Indonesian abbreviations
Malaysian Malay and Indonesian share much morphology, but workplace vocabulary is not automatically interchangeable. Indonesian PHK (pemutusan hubungan kerja) is not the ordinary Malaysian abbreviation for dismissal. In Malaysian writing, use the contextually appropriate diberhentikan kerja, pemecatan, or penamatan perkhidmatan (formal) rather than importing PHK and then attaching Malay material to it.
Kontraknya ditamatkan selepas proses tatatertib selesai.
His contract was terminated after the disciplinary process ended. (formal)
This is a lexical choice, not an affix exception. Once the correct Malaysian expression has been selected, apply the normal spelling rules to its Malay words.
Common Mistakes
Separating an ordinary prefix
❌ Saya sedang mem baca laporan itu.
Incorrect — the prefix and lowercase base do not take a space.
✅ Saya sedang membaca laporan itu.
I am reading the report.
Inserting a hyphen into an ordinary derived word
❌ Jalan itu sudah di-perbaiki.
Incorrect — ordinary affixes are written solidly.
✅ Jalan itu sudah diperbaiki.
The road has been repaired.
Removing the boundary before a proper name
❌ Program itu dilaksanakan seMalaysia.
Incorrect — se- needs a hyphen before the capitalized proper name.
✅ Program itu dilaksanakan se-Malaysia.
The programme was implemented throughout Malaysia.
Spacing a bound element after an initialism
❌ ATM nya berada di tingkat bawah.
Incorrect — -nya is bound and the capitals require a hyphen.
✅ ATM-nya berada di tingkat bawah.
Its ATM is on the lower floor.
Flattening a mixed-case base
❌ Pemohon itu sudah bermi-kad.
Incorrect — this loses the official form MyKad and creates a false boundary.
✅ Pemohon itu sudah ber-MyKad.
The applicant already has a MyKad. (administrative)
Key Takeaways
Write productive affixes solidly with ordinary lowercase bases: membaca, diperbaiki, makanan. Insert a hyphen only when the base's graphic form forces a visible boundary, as in se-Malaysia, ATM-nya, and ber-MyKad. Choose Malaysian vocabulary first; shared morphology does not make an Indonesian abbreviation such as PHK standard Malaysian usage.
