To learn Indonesian quickly and correctly, start with a small conversation you would genuinely use: greet someone, request a drink, say thank you and ask for clarification. Indonesian, or Bahasa Indonesia, uses the Latin alphabet and has many approachable sentence patterns, but pronunciation, word choice and politeness still deserve attention. This eduKateSG Quick Notes lesson teaches beginners a useful request, explains each part of the sentence, and gives you a 15-minute practice method for building accurate language rather than memorising disconnected word lists.
- Start with a real task: ask for a glass of plain water.
- Use a useful sentence: Boleh saya minta segelas air putih? means “May I have a glass of plain water?”
- Learn the chunks: boleh (may/can), saya (I), minta (ask for) and segelas air putih (a glass of drinking water).
- Change the request: practise secangkir teh (a cup of tea) and secangkir kopi (a cup of coffee).
- Use polite expressions: permisi (excuse me), terima kasih (thank you) and sama-sama (you’re welcome).
- Hide, speak and check: make a new request without notes, check one error and repeat tomorrow.
First, learn how Indonesian sounds. It uses the familiar Latin alphabet, but reading every letter as though it were English will create mistakes. For example, the letter c in cangkir (“cup”) is pronounced roughly like English ch. The letter combination ng can represent the sound at the end of English “sing”. Hear a clear recording of selamat pagi (“good morning”) and repeat it at a natural pace. Make the sound-and-meaning connection before copying a page of words. One accurately pronounced phrase is a better first step than twenty guessed pronunciations.
Second, build a sentence that performs one useful job: Boleh saya minta segelas air putih? This is a polite request for a glass of plain water. The word air in Indonesian means “water”, not the English substance you breathe; air putih is a common term for plain drinking water. The expression segelas means one glass. Now change the item: Boleh saya minta secangkir teh? (“May I have a cup of tea?”). The measure word changes because a cup of tea is more natural than a glass in this model. Learn the complete phrases before trying to swap every word independently.
Third, practise recall with a changed situation. Read the water sentence once, cover it and imagine ordering tea at a café. Speak the tea request aloud, then uncover the model and check whether you said secangkir rather than segelas. Repeat with coffee: Boleh saya minta secangkir kopi?. If you make a mistake, name the exact part—pronunciation, measurement word, word order or politeness—and say the corrected sentence. Short independent recall helps you discover what you actually know. Recognition alone is not the same as being able to speak.
Worked conversation: ask for water politely
Customer: Selamat pagi. Boleh saya minta segelas air putih?
Server: Boleh, silakan.
Customer: Terima kasih.
Server: Sama-sama.
In English: “Good morning. May I have a glass of plain water?” — “Yes, go ahead.” — “Thank you.” — “You’re welcome.” Say the entire exchange, then request tea instead. The aim is not to perform a perfect dramatic dialogue; it is to choose the right sentence at the right moment.
Six Indonesian expressions worth learning first
- Selamat pagi — good morning.
- Permisi — excuse me, often used to get attention or pass someone.
- Terima kasih — thank you.
- Sama-sama — you’re welcome.
- Nama saya … — my name is …
- Saya tidak mengerti — I do not understand.
- Bisa ulangi, tolong? — could you repeat it, please? in a suitable informal situation.
Each phrase should be attached to a little scene. Imagine arriving in a shop, greeting the cashier, asking for water and thanking them. Then imagine you cannot understand the reply. Say Saya tidak mengerti and request repetition. A small conversation teaches you how words work together, which is more practical than learning translations without any situation.
Quick grammar: tidak and bukan
Indonesian does not simply use one English-like “not” in every sentence. Tidak commonly negates verbs, adjectives and related expressions: Saya tidak mengerti means “I do not understand.” Bukan commonly negates a noun identification: Ini bukan kopi means “This is not coffee.” Start with those two complete examples. Do not try to apply a simplified rule to every advanced expression; learn the dependable beginner distinction, then encounter exceptions through real language.
What segelas and secangkir reveal
The element se- can mark “one” in these common measure expressions: segelas (one glass) and secangkir (one cup). You might also meet sebotol air (“a bottle of water”). Indonesian does not require the same kind of article as English “a” or “the” in every context. When a quantity is important, use a correct counting or measure expression. When it is not, a shorter phrase can sometimes be natural. Work with a verified sentence rather than assuming all objects behave identically.
Saya ingin, saya mau and boleh saya
Saya ingin air putih expresses “I want drinking water” in a straightforward, often more neutral or deliberate way. Saya mau air putih is a common everyday expression of wanting water. Boleh saya minta air putih? frames the request as asking permission to receive it. These expressions perform similar practical jobs but are not identical in tone or nuance. Start with one reliable polite request; add a second pattern when the first has become easy.
Indonesian and Malay: similar does not mean identical
If you already know Malay from Singapore or Malaysia, Indonesian will contain many familiar words. Both have related vocabulary and grammatical patterns, but they also have different standard words and everyday expressions. An Indonesian learner commonly says air putih for plain drinking water, while someone using Malay may simply say air kosong for plain water in a dining context. Avoid assuming that every similar-looking sentence is interchangeable. Choose a standard Indonesian model for Indonesian practice, then compare variants with care.
Your 15-minute Indonesian study routine

A realistic first seven days
- Day 1: practise selamat pagi and terima kasih.
- Day 2: introduce yourself with Nama saya ….
- Day 3: request a glass of plain water politely.
- Day 4: change the request to tea and coffee, checking the measure words.
- Day 5: use Saya tidak mengerti and request repetition.
- Day 6: compare tidak and bukan in two example sentences.
- Day 7: speak a short exchange without notes, check accuracy and repair your two weakest phrases.
Mistakes to correct immediately
- Reading Indonesian as English: listen to how c and ng sound.
- Confusing air with English air: remember air means water in Indonesian.
- Using one measure word for everything: learn segelas air and secangkir teh as complete phrases.
- Mixing tidak and bukan at random: start with a clear correct sentence for each.
- Assuming Malay and Indonesian are identical: notice shared words without ignoring differences.
- Counting copied words as mastery: make a request with a new item from memory.
Try three questions without looking
- How would you politely request a cup of coffee using Boleh saya minta…??
- What does air putih mean?
- Which word best completes Ini ___ kopi (“This is not coffee”): tidak or bukan?
Answers: 1. Boleh saya minta secangkir kopi? 2. Plain drinking water. 3. Bukan. If a response is missing, check the exact model, speak it correctly and retrieve it again after a short delay.
How to recognise correct progress
At the end of a short lesson, you should be able to understand a familiar request, use its structure with a different drink, greet someone politely and identify the particular error in a sentence. One week does not create fluency. It gives you a small, reliable set of expressions you can keep extending through listening, reading and real conversations.
