Thanks and Responses | Indonesian Grammar

Terima kasih is the standard Indonesian gratitude formula across everyday, professional, and formal settings. It does not inflect for who thanks whom, and learners should not build its modern meaning by translating terima “receive” and kasih “give/love” word by word. Treat the two-word expression as one social formula whose strength comes from modifiers, specificity, address, and delivery.

This page also distinguishes makasih, terima kasih banyak, banyak terima kasih, sama-sama, and kembali, with a limited note on local-language replies. It is not a full regional survey.

The core formula does not change form

The same terima kasih works for one speaker or many, one addressee or an institution, and small or large benefits. Pronouns and agreement do not alter it.

Terima kasih sudah membukakan pintu.

Thank you for opening the door.

Terima kasih, Bu, penjelasannya sangat membantu.

Thank you, ma’am; your explanation was very helpful.

Kami mengucapkan terima kasih kepada seluruh relawan.

We express our thanks to all the volunteers. (formal)

Atas perhatian dan kerja sama Anda, kami ucapkan terima kasih.

We thank you for your attention and cooperation. (formal written formula)

In a fuller formal sentence, kepada marks the person thanked and atas introduces the reason. In ordinary speech, terima kasih sudah + verb is warmer and more direct.

Terima kasih sudah menjemput saya di stasiun tadi malam.

Thank you for picking me up at the station last night.

Terima kasih atas bantuan Bapak selama proses pendaftaran.

Thank you for your help during the registration process, sir. (formal)

💡

Specific gratitude is stronger than repeated gratitude. Naming the action—waiting, explaining, checking—shows that you noticed the other person’s actual contribution.

Terima kasih banyak and banyak terima kasih

Terima kasih banyak is the ordinary emphatic “thank you very much” in speech and writing. Banyak terima kasih also occurs, especially as a deliberate (formal) or somewhat elevated opening or closing formula, but it is less conversational for many speakers.

Terima kasih banyak sudah menjaga kucing kami selama liburan.

Thank you very much for looking after our cat during the holiday.

Terima kasih banyak, Pak; tanpa bantuan Bapak kami pasti terlambat.

Thank you very much, sir; without your help we would certainly have been late.

Banyak terima kasih kami sampaikan kepada para narasumber yang telah hadir.

We extend our many thanks to the speakers who attended. (formal)

Banyak terima kasih atas sambutan yang begitu hangat.

Many thanks for such a warm welcome. (formal/elevated)

For everyday conversation, choose terima kasih banyak. Neither order changes for plural speakers.

Makasih belongs to casual interaction

Makasih is a common reduction of terima kasih (informal). It is natural among friends, siblings, and relaxed coworkers, especially in messages. Keep it out of official letters, academic acknowledgments, and careful customer notices unless the institution deliberately adopts a youthful conversational voice. The casual spoken register guide places this reduction within the wider colloquial system.

Makasih sudah ingetin aku soal rapat besok!

Thanks for reminding me about tomorrow’s meeting! (peer message; informal)

Makasih, ya, sudah nemenin aku ke klinik tadi.

Thanks for coming with me to the clinic earlier. (close peer; informal)

Oke, berkasnya sudah aku terima. Makasih banyak!

Okay, I’ve received the file. Thanks a lot! (peer message; informal)

Makasih banget buat hadiahnya; aku suka warnanya.

Thanks so much for the gift; I love the color. (close peer; informal)

The surrounding forms ingetin, nemenin, aku, banget, and buat reinforce the informal register. Standard equivalents include mengingatkan, menemani, saya, sekali, and untuk/atas, depending on syntax.

Four everyday exchanges

Service

Pelanggan: Terima kasih, Mbak, pesanannya sudah lengkap.

Customer: Thank you, miss; the order is complete.

Pelayan: Sama-sama, Pak. Semoga makanannya sesuai selera.

Server: You’re welcome, sir. I hope you enjoy the food.

Receiving a gift

Terima kasih banyak atas bukunya, Tante. Saya sudah lama ingin membacanya.

Thank you very much for the book, Auntie. I’ve wanted to read it for a long time.

Sama-sama. Tante senang kamu menyukainya.

You’re welcome. I’m glad you like it.

Receiving a favor

Terima kasih sudah menggantikan giliran saya sore ini, Rudi.

Thank you for covering my shift this afternoon, Rudi.

Tidak masalah. Nanti kalau saya perlu bantuan, gantian, ya.

No problem. If I need help later, it’ll be your turn, okay? (friendly peer exchange)

A peer message

Makasih udah kirim catatannya. Aku jadi bisa belajar malam ini.

Thanks for sending the notes. Now I can study tonight. (informal message)

Santai, sama-sama! Kalau ada yang kurang jelas, kabari aja.

No worries, you’re welcome! If anything is unclear, let me know. (informal message)

Colloquial udah and aja belong inside this clearly (informal) exchange; neutral exposition keeps standard sudah and saja.

Sama-sama: the general response

Sama-sama is the most broadly useful response to thanks. Historically and compositionally it contains sama, but its response meaning is formulaic: do not translate it mechanically as “same-same.” It can sound warm, neutral, or professional depending on delivery and what follows.

“Terima kasih atas waktunya.” “Sama-sama, senang bisa membantu.”

‘Thank you for your time.’ ‘You’re welcome; I’m glad I could help.’

Sama-sama, Bu. Jika ada pertanyaan lain, silakan hubungi kami.

You’re welcome, ma’am. If you have any other questions, please contact us.

Sama-sama. Semoga perjalanan Bapak menyenangkan.

You’re welcome. I hope you have a pleasant journey, sir.

It is never necessary to mirror the exact length of the thanks. A short sama-sama can answer an elaborate expression, although a specific friendly addition often sounds more engaged.

Kembali in service and formal exchanges

Kembali can function as a short response to thanks, especially in service encounters, presentations, and careful speech. It is formulaic here; it does not literally instruct the other person to “return.” The fuller terima kasih kembali reciprocates thanks: “thank you too.”

“Terima kasih atas informasinya, Pak.” “Kembali, Bu.”

‘Thank you for the information, sir.’ ‘You’re welcome, ma’am.’ (careful/service exchange)

Terima kasih kembali atas kepercayaan yang telah diberikan kepada kami.

We thank you in return for the trust you have placed in us. (formal spoken)

Kembali, Pak. Dokumennya akan kami kirim sore ini.

You’re welcome, sir. We’ll send the document this afternoon. (service)

In everyday peer conversation, sama-sama is generally the safer active choice. Kembali may sound more service-like or formulaic, depending on the speaker and region.

Other natural responses

Indonesian responses can minimize the burden, express pleasure, or emphasize mutuality. Choose a response that truthfully fits the favor.

Tidak apa-apa, kebetulan saya lewat jalan yang sama.

It’s no trouble; I happened to be going the same way.

Dengan senang hati, Bu. Saya juga belajar banyak dari kegiatan ini.

With pleasure, ma’am. I also learned a lot from this activity.

Senang bisa membantu. Semoga urusannya cepat selesai.

Glad to help. I hope the matter is resolved quickly.

Kita sama-sama terbantu, jadi tidak perlu sungkan.

We both benefited, so there’s no need to feel indebted.

Regional and local-language replies

Indonesians often switch into a local language to match community identity. Sami-sami is heard as a reciprocal response in some Javanese-speaking settings (regional: Javanese; local-language code-switching). It is not a replacement to insert into standard Indonesian everywhere.

“Matur nuwun, Pak.” “Sami-sami.”

‘Thank you, sir.’ ‘You’re welcome.’ (regional: Javanese; respectful local-language exchange)

Learn such replies from the community where you use them. Nationally portable Indonesian remains terima kasih — sama-sama.

💡

A local response indexes belonging as well as gratitude. Use it when you understand its speech level and community setting, not merely because it sounds warmer.

Common Mistakes

1. Writing the formula as one word

❌ Terimakasih atas bantuannya.

Incorrect standard spelling — terima kasih is two words.

✅ Terima kasih atas bantuan Anda hari ini.

Thank you for your help today.

2. Using makasih in a formal letter

❌ Makasih banget atas kerja sama instansi Anda.

Inappropriate for a formal institutional letter.

✅ Kami mengucapkan terima kasih atas kerja sama instansi Anda.

We thank your institution for its cooperation. (formal)

3. Translating the words inside terima kasih literally

❌ Ungkapan “terima kasih” berarti menerima kasih dari orang lain.

Incorrect word-for-word analysis — modern terima kasih is a fixed gratitude formula.

✅ Saya sangat berterima kasih atas dukunganmu.

I’m very grateful for your support.

4. Replying with an English calque of “welcome”

❌ “Terima kasih.” “Selamat datang.”

Incorrect response — selamat datang welcomes someone on arrival.

✅ “Terima kasih.” “Sama-sama.”

‘Thank you.’ ‘You’re welcome.’

5. Using a regional reply without the matching setting

❌ Sami-sami dianggap sebagai satu-satunya jawaban baku bahasa Indonesia.

Incorrect — this is a local-language form, not the sole standard Indonesian reply.

✅ Dalam bahasa Indonesia baku, jawaban yang paling luas dipakai adalah sama-sama.

In Standard Indonesian, the most widely used reply is sama-sama.

Key Takeaways

Terima kasih is a fixed two-word formula and does not inflect.
Terima kasih banyak is the ordinary emphatic form; banyak terima kasih is more deliberate or formal.
Makasih is (informal) and belongs to relaxed speech and messaging.
Sama-sama is the most portable response; kembali is common in careful and service exchanges.
Regional replies carry local identity and speech-level information, so learn them in context.
