-kan versus -i: Advanced Constraints and Register in Malaysian Malay | Malay Grammar

At advanced level, -kan versus -i is best understood as object selection inside Malay's wider voice system. The suffix determines whether a theme, recipient, or location is the primary object; actor voice, di- passive, and object voice then decide which participant anchors the clause. This two-stage analysis explains extraction facts that an English “direct versus indirect object” template misses.

The contrast is also strongly lexical and register-sensitive. Some -i verbs are frequent Malaysian vocabulary; others are grammatical but uncommon beside an analytic -kan ... kepada/ke dalam ... construction or a different everyday verb. This page covers those constraints rather than repeating the basic frames introduced in the series overview.

Object relatives follow suffix choice

In formal Malay, a passive relative gives the clearest route for relativizing the selected object.

Surat yang dikirimkan kepada Rina itu mengandungi keputusan temu duga.

The letter sent to Rina contains the interview result.

Rina, yang dikirimi surat itu semalam, diminta mengesahkan penerimaannya.

Rina, who was sent the letter yesterday, was asked to confirm receipt. (formal)

Barang yang dimasukkan ke dalam kotak itu ialah bekalan perubatan.

The items put into the box are medical supplies.

Kotak yang dipenuhi dengan bekalan perubatan itu telah dimeterai.

The box filled with medical supplies has been sealed.

Each relative head corresponds to the suffix-selected object: surat/barang with -kan, Rina/kotak with -i. The actor may remain absent or be supplied in an oleh phrase.

💡

When an object relative sounds doubtful, build its passive first. If the intended head becomes the natural subject of dikirimkan/dimasukkan or dikirimi/dipenuhi, the suffix alignment is visible.

Object voice retains the suffix but loses meN-

Malay object voice can place a definite object before a first- or second-person actor. The actor-voice prefix meN- disappears, while -kan or -i remains attached to the root.

Surat itu saya kirimkan kepada Rina sebelum tengah hari.

That letter, I sent to Rina before noon.

Rina saya kirimi surat setiap bulan ketika dia berada di luar negara.

Rina, I sent a letter every month while she was abroad. (marked/formal recipient-centered object voice)

Barang itu kami masukkan ke dalam kotak berkunci.

Those goods, we put into a locked box.

Kotak berkunci itu kami penuhi dengan dokumen asal.

That locked box, we filled with original documents.

The -i object-voice examples are structurally revealing but less frequent in ordinary Malaysian usage than actor-voice or analytic rephrasings. Advanced grammar must distinguish “licensed” from “preferred in this genre.” With a first-person actor, however, Rina dikirimi surat oleh saya is not the standard alternative: Malaysian Malay requires object voice Rina saya kirimi surat. A writer who finds that recipient-first order too marked can use Saya mengirimi Rina surat or restructure the passage.

Relative clauses can use the same object-voice architecture, especially in less formal style: surat yang saya kirimkan kepada Rina. With a third-person noun actor, careful prose generally favors surat yang dikirimkan oleh Amir, while surat yang Amir kirimkan is widespread in speech and less formal writing.

Extraction limits reveal the promoted object

An oblique recipient after mengirimkan is not the same kind of object as a recipient after mengirimi. Simply removing kepada does not create a well-formed recipient relative.

❌ Rina yang Amir mengirimkan surat itu sudah membalas.

Incorrect—the -kan frame does not license Rina as this direct-object gap.

✅ Rina yang dikirimi surat itu oleh Amir sudah membalas.

Rina, who was sent the letter by Amir, has replied.

Conversely, the secondary theme after mengirimi is not the primary object selected for straightforward promotion:

❌ Surat yang Amir mengirimi Rina itu belum sampai.

Incorrect—the intended extracted theme requires the -kan frame.

✅ Surat yang dikirimkan oleh Amir kepada Rina itu belum sampai.

The letter that Amir sent to Rina has not arrived.

Malay can also preserve an oblique relation overtly—Rina, yang kepadanya surat itu dikirimkan (formal/literary)—but this is stylistically heavy. Recipient-passive yang dikirimi surat is usually more economical when Rina is the intended head.

💡

Extraction is not a reason to delete a preposition at random. Either retain the oblique relation in an appropriate formal structure or choose the suffix that promotes the intended head before relativizing it.

Lexical exceptions and semantic drift

The neat transfer and container pairs are models, not a fully productive equation. Lexicalized forms can narrow, broaden, or depart from a spatial/recipient interpretation.

Form	Established meaning	Why simple decomposition fails
memenuhi syarat	meet requirements	no literal container is filled
menduduki jawatan	hold/occupy a position	location is institutional and lexicalized
mengetahui perkara itu	know that matter	not a repeated application of “know”
menyukai muzik itu	like that music	final -i belongs to an established psych verb
mendatangkan faedah	bring/cause benefits	-kan form is causative, not a theme version of every mendatangi use

Roots ending in i create further surface ambiguity. Memberi and mengisi do not contain a visibly detachable extra -i just because they end with that letter. Standard spelling never doubles the vowel mechanically. Valency and lexical history, not orthographic appearance alone, determine the analysis.

Corpus-realistic use therefore requires lexical knowledge. Malaysian formal prose readily uses memenuhi syarat, menghadiri mesyuarat, and mengetahui bahawa; recipient-centered mengirimi is standard but often less common than mengirimkan ... kepada ... or everyday menghantar ... kepada .... A theoretically imaginable derivative is not automatically idiomatic.

Agentless passives are real passives

Unlike an intransitive with an omitted subject, dikirimkan, dikirimi, dimasukkan, and dipenuhi carry attached passive di- and promote a patient. The actor can be omitted when unknown, generic, recoverable, or irrelevant.

Surat keputusan telah dikirimkan kepada semua calon.

The decision letters have been sent to all candidates. (formal)

Semua calon yang berjaya telah dikirimi surat keputusan.

All successful candidates have been sent decision letters. (formal)

Barang terlarang tidak boleh dimasukkan ke dalam bungkusan ini.

Prohibited items may not be put into this parcel.

Ruang menunggu dipenuhi oleh ahli keluarga pesakit sejak awal pagi.

The waiting area has been filled with patients' family members since early morning.

The absence of oleh does not make the passives defective. It reflects discourse choice. Adding an actor is appropriate only when the identity contributes useful information.

Annotated formal paragraph

Surat tawaran telah dikirimkan kepada Rina, manakala calon lain yang belum dikirimi surat diminta menunggu. Di pusat pengumpulan, barangan bantuan dimasukkan ke dalam kotak mengikut kategori sebelum setiap kotak dipenuhi dengan bekalan tambahan dan dimeterai.

The offer letter was sent to Rina, while other candidates who had not yet been sent letters were asked to wait. At the collection center, aid supplies were put into boxes by category before each box was filled with additional supplies and sealed. (formal administrative report)

The paragraph makes four deliberate choices:

surat tawaran ... dikirimkan tracks a particular document;
calon ... dikirimi surat makes recipients the relative heads;
barangan ... dimasukkan tracks items moving into boxes;
kotak dipenuhi shifts topic to containers affected toward fullness.

The passive actors are omitted because procedure and participant status matter more than the staff performing each action. Attached prefixes and suffixes remain intact; locative Di pusat pengumpulan is separate.

Colloquial exchange

“Surat tu dah hantar kat Rina?” “Dah. Barang ni pula, masukkan dalam kotak biru, tapi jangan sumbat sampai penuh sangat.”

‘Has that letter been sent to Rina?’ ‘Yes. Put these things in the blue box, but don't cram it too full.’ (informal Malaysian dialogue)

Colloquial Malaysian often uses hantar rather than mengirimkan/mengirimi, uses kat beside formal kepada, drops ke in a highly recoverable direction such as masukkan dalam, and selects lexical sumbat “cram.” These forms do not prove that the standard suffixed system is artificial, nor are they always exact structural substitutes:

bare hantar leaves the formal theme–recipient alignment less morphologically explicit;
masukkan retains -kan even though actor-voice meN- is absent in a command;
sumbat adds a manner and density meaning absent from neutral memenuhi.

Calling every colloquial analytic construction “wrong” would misrepresent Malaysian usage. Calling every formal -i alternative equally common would be just as misleading.

The symmetrical voice ecology

Malay allows the suffix to select an object and voice to choose how that object enters discourse:

Alignment	Actor voice	di- passive with third-person actor	Object voice with first-person actor
theme -kan	saya mengirimkan surat	surat dikirimkan oleh Amir	surat saya kirimkan
recipient -i	saya mengirimi Rina surat	Rina dikirimi surat oleh Amir	Rina saya kirimi surat

The actor differs across the last two columns deliberately. Standard di- passive illustrates a third-person agent such as Amir; first-person saya instead appears immediately before the unprefixed verb in object voice.

This is why “active adds meN-, passive adds di-” is incomplete. Object selection by -kan/-i feeds a discourse-oriented voice alternation in which actor and patient perspectives are systematically related. The -i option may be lexically restricted, but when licensed it changes the architecture available to relativization and topicality.

Common Mistakes

1. Retaining meN- in an object relative

❌ Surat yang saya mengirimkan kepada Rina itu sulit.

Incorrect standard object voice—meN- cannot remain after saya in this relative.

✅ Surat yang saya kirimkan kepada Rina itu sulit.

The letter that I sent to Rina is confidential.

2. Extracting the -kan oblique as though it were the object

❌ Rina yang saya mengirimkan surat sudah menjawab.

Incorrect—the recipient remains oblique in the -kan frame.

✅ Rina yang saya kirimi surat sudah menjawab.

Rina, whom I sent a letter, has replied. (marked/formal object voice)

3. Splitting passive di-

❌ Kotak itu di penuhi dengan bekalan makanan.

Incorrect—the passive prefix di- is attached.

✅ Kotak itu dipenuhi dengan bekalan makanan.

The box was filled with food supplies.

4. Switching suffix while retaining the old passive subject

❌ Barang itu dipenuhi ke dalam kotak.

Incorrect—barang is the moved theme and requires dimasukkan in this frame.

✅ Barang itu dimasukkan ke dalam kotak.

The goods were put into the box.

5. Treating a colloquial alternative as structurally identical

⚠️ Aku hantar Rina surat tu.

Possible in some colloquial varieties, but its argument pattern should not be used to infer the formal -kan/-i system.

✅ Saya mengirimkan surat itu kepada Rina.

I sent the letter to Rina. (neutral/formal theme-centered frame)

Key Takeaways

Relative clauses and object voice expose which participant -kan or -i selected. Object voice retains the suffix but drops actor-voice meN-; passive voice attaches di- and may omit its actor. The alternation is lexically restricted, and many derived verbs have conventional meanings that cannot be calculated from a spatial diagram. Formal and colloquial Malaysian patterns coexist, while suffix selection and voice choice jointly determine discourse perspective.
