kerana and sebab | Malay Grammar

Malaysian Malay most often introduces a reason with kerana “because” (neutral; spoken and written) or sebab (neutral to informal as a linker; all registers as a noun). Both can answer why, but they are not identical grammatical categories. Kerana is straightforwardly a subordinating linker, whereas sebab visibly moves between the noun “cause/reason” and a clause-linking use.

That difference explains several patterns that otherwise look arbitrary. In a clearly nominal frame, sebab kelewatan itu means “the cause of that delay,” whereas kerana kelewatan itu means “because of that delay.” On its own, however, sebab kelewatan itu can be ambiguous because everyday usage also permits a causal reading. English because and reason are separate words; Malay lets sebab cover part of both territories. This page treats reason clauses and nominal causes, not conditional meaning, the sequencing of a whole argument, or unrelated lexical uses of prepositions. The broader cause-and-result guide develops longer and more complex causal structures.

Kerana introduces a reason clause

Kerana marks the subordinate proposition as the explanation for the main proposition. The reason can follow the outcome, which is the usual unmarked order in conversation:

Saya pulang awal kerana badan kurang sihat.

I went home early because I wasn't feeling well.

Mesyuarat itu ditangguhkan kerana pengerusi masih berada di luar negara.

The meeting was postponed because the chairperson is still abroad. (neutral-formal)

The reason may also come first. An initial reason frames everything that follows, so a comma normally marks the end of that subordinate clause:

Kerana jalan utama ditutup, kami terpaksa menggunakan laluan lain.

Because the main road was closed, we had to use another route.

Fronting is useful when the cause is already under discussion or when the writer wants it to guide the reader's interpretation. A final kerana clause instead lets the outcome arrive first and then supplies its explanation.

💡

Clause order changes information flow, not the causal direction. Kerana jalan ditutup, kami berpatah balik and Kami berpatah balik kerana jalan ditutup both make the closure the cause.

Sebab as a linker

In Malaysian conversation, sebab commonly introduces a reason clause (neutral spoken/informal). It is especially natural when the explanation follows the main clause or stands alone as an answer.

Saya tak ikut sebab saya kena kerja malam ini.

I'm not coming along because I have to work tonight. (informal)

Aina: Kenapa awak tak bawa kereta? Ravi: Sebab kereta saya masih di bengkel.

Aina: Why didn't you bring your car? Ravi: Because my car is still at the workshop. (conversation)

The second answer is deliberately elliptical: Sebab kereta saya masih di bengkel is not an independent assertion in careful written syntax. Conversation supplies the unspoken result—“I did not drive”—from the question. English also permits the fragment “Because my car is in the shop,” so this use feels familiar.

Sebab can be fronted too, especially in speech, although kerana or oleh sebab is usually smoother in edited formal prose:

Sebab hujan lebat, kami tunggu di kedai dulu.

Because it was raining heavily, we waited at the shop for a while. (informal spoken)

Oleh sebab hujan lebat, acara di padang itu terpaksa dibatalkan.

Because of the heavy rain, the event on the field had to be cancelled. (formal)

There is no need to ban clause-linking sebab from every piece of writing; it is established Malaysian usage. The real choice is register and structure. Kerana is the broadly neutral conjunction, while initial bare sebab sounds more conversational. Prescriptive school, administrative, and closely edited formal prose generally treats sebab as a noun, so kerana or oleh sebab is the safer choice in those settings.

Sebab as a noun: “cause” or “reason”

Unlike kerana, sebab can head a noun phrase. It can take a determiner, occur after a preposition, be possessed, and serve as the subject or complement of a clause.

Polis masih menyiasat sebab kebakaran itu.

The police are still investigating the cause of the fire.

Itulah sebab saya menghubungi puan pagi tadi.

That is the reason I contacted you this morning.

Atas sebab keselamatan, pintu belakang akan dikunci selepas pukul sepuluh malam.

For safety reasons, the back door will be locked after ten at night. (formal)

In sebab kebakaran itu, the following phrase may be interpreted as identifying the event whose cause is being investigated: “the cause of the fire.” By contrast, kerana kebakaran itu unambiguously presents the fire as the reason for some other outcome: “because of the fire.” The surrounding predicate and structure matter.

Form	Grammatical role	Typical register
kerana + clause / phrase	subordinate reason	neutral; spoken and written
sebab + clause	reason linker	neutral spoken to informal
sebab + noun phrase	noun “cause/reason”	all registers
oleh sebab + noun phrase / clause	explicit causal frame	neutral-formal to formal

Sebab itu and oleh sebab itu

Sebab itu “that is why/for that reason” points back to a cause already stated and introduces its consequence. It is common in speech and neutral prose. Oleh sebab itu is the fuller, more formal connector.

Bas terakhir sudah bertolak. Sebab itu kami terpaksa mengambil teksi.

The last bus had already left. That's why we had to take a taxi.

Kos bahan mentah telah meningkat. Oleh sebab itu, harga jualan perlu disemak semula.

Raw-material costs have increased. Therefore, the selling price needs to be reviewed. (formal)

These expressions are sentence-connecting frames, not replacements inside every kerana clause. The cause has already been presented; itu retrieves it. A comma after initial oleh sebab itu is conventional in careful writing because the phrase frames the following independent clause. Short sebab itu is also often followed by a comma in edited prose, though the pause may be lighter.

Do not confuse this backward-pointing pattern with kerana itu used directly before a noun. In current standard prose, oleh sebab itu is the clearest formal choice for “for that reason.”

Spoken ellipsis and careful writing

Conversation often omits recoverable material:

Tak jadi keluar—hujan lebat sangat.

We're not going out after all—the rain is really heavy. (informal; the causal relation is inferred)

Tak jadi keluar sebab hujan lebat sangat.

We're not going out after all because the rain is really heavy. (informal; the cause is explicit)

The first utterance has no linker, but the situation invites a causal interpretation. The second prevents doubt. Formal writing should not rely on conversational fragments when the logical relationship matters; use kerana, oleh sebab, or a complete sentence with oleh sebab itu.

💡

Do not choose purely by translation. Ask whether you need a conjunction introducing a reason (kerana), conversational clause linkage (sebab), or an actual noun meaning “cause/reason” (sebab).

Common Mistakes

Treating kerana as a noun

❌ Polis menyiasat kerana kebakaran itu.

Wrong for the intended meaning ‘the cause of the fire’—kerana makes the fire itself the reason for investigating.

✅ Polis menyiasat sebab kebakaran itu.

The police are investigating the cause of the fire.

Using bare sebab as the safest formal opening

❌ Sebab permohonan tidak lengkap, permohonan tersebut tidak dapat diproses.

✅ Oleh sebab permohonan tidak lengkap, permohonan tersebut tidak dapat diproses.

Because the application is incomplete, it cannot be processed. (formal)

Doubling two reason linkers

❌ Kerana sebab jalan ditutup, kami lewat.

Incorrect—kerana and clause-linking sebab compete for the same causal boundary here.

✅ Kerana jalan ditutup, kami lewat.

Because the road was closed, we were late.

Omitting punctuation after a long fronted reason

❌ Oleh sebab semua dokumen sokongan masih belum diterima permohonan itu belum dapat diluluskan.

Hard to parse—the long initial reason clause needs a visible boundary.

✅ Oleh sebab semua dokumen sokongan masih belum diterima, permohonan itu belum dapat diluluskan.

Because not all supporting documents have been received, the application cannot yet be approved. (formal)

Key Takeaways

Kerana is the broadly neutral subordinating linker for reasons.
Clause-linking sebab is especially natural in Malaysian conversation; noun sebab means “cause” or “reason.”
A fronted reason normally takes a comma; a final reason normally does not.
Sebab itu and formal oleh sebab itu retrieve a previously stated cause and introduce its consequence.
English because does not capture every use of sebab: decide first whether the Malay expression is a linker or a noun.
