The bound forms -ku, -mu, and -nya attach directly to a preceding host. On a noun, they commonly express a possessor: bukuku “my book” and gurumu “your teacher.” On a verb, they can express an object: melihatnya “see him/her/it.” After a preposition, they express its complement: kepadaku “to me.”
The spelling is always tight, but the grammatical relation is not stored in the clitic alone. The host type and sentence context tell the listener whether the form means possessor, object, prepositional complement, or a broader discourse-anchoring use of -nya. This page introduces the shared system while leaving demonstratives, full relative-clause syntax, and voice paradigms to dedicated adjacent pages.
The three suffixal forms
| Clitic | Typical person | After a noun | After a verb |
|---|---|---|---|
| -ku | first singular | bukuku “my book” | melihatku “see me” |
| -mu | second singular familiar | gurumu “your teacher” | membantumu “help you” |
| -nya | third person; salient entity | rumahnya “his/her/their/the house” | melihatnya “see him/her/it” |
Bukuku tertinggal di ruang kelas.
My book was left in the classroom.
Gurumu sudah menunggu di depan kantor.
Your teacher is already waiting in front of the office.
Saya melihatnya di stasiun kemarin.
I saw him/her/it at the station yesterday.
English changes the shape of full pronouns—I/me/my and he/him/his. Indonesian clitics are more economical: one bound form can appear with different hosts, and the construction supplies the relation.
Possession after nouns
The clitic follows the possessed noun, matching ordinary Indonesian possessed-before-possessor order.
Ponselku sedang diisi daya.
My phone is charging.
Apakah adikmu ikut makan malam?
Is your younger sibling joining dinner?
Rumahnya besar, tetapi halamannya sempit.
His/Her house is large, but its yard is narrow.
Compare bound and full possessors:
| Bound | Full | Register/meaning note |
|---|---|---|
| bukuku | buku aku / buku saya | -ku compact and personal; saya neutral-polite |
| bukumu | buku kamu | familiar second person |
| bukunya | buku dia / buku mereka | gender and number often resolved by context |
Full pronouns remain separate, while clitics attach. With a spaced compound, the clitic attaches to its final written word: meja makanmu “your dining table.” It does not erase the internal space.
Objects after verbs
A clitic attached to a transitive verb can express its object.
Mereka melihatku masuk ke gedung itu.
They saw me enter that building.
Aku akan membantumu setelah makan siang.
I'll help you after lunch.
Kami sudah menghubunginya beberapa kali.
We have contacted him/her several times.
The verb keeps its correct morphology: lihat → melihat, bantu → membantu, and hubung + -i → menghubungi. The clitic is added after the complete verb: melihat-ku, membantu-mu, menghubungi-nya in morphological analysis, but ordinary spelling removes the analytic hyphens: melihatku, membantumu, menghubunginya.
After prepositions
The same suffixes attach to prepositions and similar relational words:
| Form | Meaning |
|---|---|
| kepadaku | to me |
| untukmu | for you |
| dengannya | with him/her/it |
| olehnya | by him/her/it |
| padanya | on/to him/her/it, depending on construction |
Hadiah ini untukmu, bukan untukku.
This gift is for you, not for me.
Saya sudah berbicara dengannya tentang masalah itu.
I have spoken with him/her about that problem.
These are not separate pronoun words written after the preposition. Kepada aku and dengan dia are possible with full pronouns in suitable contexts; kepadaku and dengannya are the bound alternatives.
Stacking after derivational suffixes
Clitics attach at the outer edge of an already formed word. In memberikannya, the verb contains derivational -kan, followed by object -nya:
| Layer | Form | Contribution |
|---|---|---|
| root | beri | give |
| voice/derivation | memberikan | give something to/for someone |
| object clitic | memberikannya | give it/him/her |
| recipient phrase | kepadaku | to me |
Rina memberikannya kepadaku setelah rapat.
Rina gave it to me after the meeting.
The spelling memberikannya kepadaku contains two solid words because there are two hosts: -nya attaches to the verb, and -ku attaches to the preposition. The nasal form is memberikan, never menberikan.
Other combinations follow the same edge principle: menjelaskannya “explain it,” mengirimkannya “send it,” and membacakannya “read it aloud.” With verbs that introduce several participants, context and argument structure determine which participant -nya represents; the verb pages develop those patterns in detail.
Several meanings of -nya
-Nya is broader than English his/her. It can refer to a person, an object, a plural possessor, or an already salient entity. Thus bukunya may mean “his book,” “her book,” “their book,” or simply “the book in question.”
Bukunya sudah saya kembalikan ke perpustakaan.
I've returned the book to the library.
Nothing in that sentence requires a human possessor. Context may identify the book itself. The dedicated -nya page covers definiteness, nominalization, and stance uses beyond the basic clitic paradigm.
Register and emphasis
-Ku and -mu are common in intimate speech (informal) and in personal or lyrical writing (literary); they also appear in fully standard fixed and written constructions. Full saya and a respectful title may be more appropriate when social distance matters (formal). -Nya is neutral and extremely widespread across registers.
Using a full pronoun can add contrast: Buku itu untuk kamu, bukan untuk dia. Bound untukmu is more compact. The choice is therefore not only shorter versus longer; it can shift rhythm, emphasis, and social stance.
Orthography
Attach -ku, -mu, and -nya without a space or ordinary hyphen: bukuku, gurumu, melihatnya. The corresponding preverbal forms ku- and kau- also attach: kubaca, kaubaca. If the host is an all-capital abbreviation, EYD V uses a hyphen, as in KTP-nya. Full Anda remains separate and capitalized. Titles take capitals only where prescribed. Ordinary Indonesian has no mandatory accent marks.
Common Mistakes
1. Spacing possessive -ku
❌ Buku ku tertinggal di kelas.
Incorrect spelling — -ku attaches to buku.
✅ Bukuku tertinggal di kelas.
My book was left in the classroom.
2. Spacing possessive -mu
❌ Guru mu sedang menunggu.
Incorrect spelling — -mu attaches to guru.
✅ Gurumu sedang menunggu.
Your teacher is waiting.
3. Spacing object -nya
❌ Saya melihat nya di stasiun.
Incorrect spelling — object -nya attaches to the verb.
✅ Saya melihatnya di stasiun.
I saw him/her/it at the station.
4. Splitting clitics from both hosts
❌ Tono memberikan nya kepada ku.
Incorrect spelling — each clitic must attach to its own host.
✅ Tono memberikannya kepadaku.
Tono gave it to me.
5. Misspelling the nasal verb before attachment
❌ Rina menberikannya kepadaku.
Incorrect morphophonemic form — beri takes mem- in memberi/memberikan.
✅ Rina memberikannya kepadaku.
Rina gave it to me.
Key Takeaways
- Attach -ku, -mu, and -nya directly to a noun, verb, or preposition.
- The host determines whether the clitic expresses possession, an object, or a prepositional complement.
- Form the verb correctly before attachment: menghubunginya and memberikannya.
- In memberikannya kepadaku, each clitic attaches to a different host.
- Do not translate every -nya as “his” or “her.”
