No separate word for a or an
In Indonesian, there is no direct equivalent to the English articles 'a' or 'an'. To say 'a book', you usually just say 'book' (buku) or use a specific counter called a classifier (sebuah buku).
How It Works
Unlike English, which requires an article for singular countable nouns (e.g., 'I have a car'), Indonesian allows nouns to stand alone. This is called a 'bare noun'.
1. The Bare Noun (Default)
In everyday conversation, if the exact quantity isn't the main point, Indonesians simply use the noun. For example, Saya beli jeruk can mean 'I bought an orange' or 'I bought oranges'. The focus is on the action and the object, not the count.
2. Using Classifiers for 'A/An'
When you want to introduce a new specific object or emphasize that there is exactly one, you use a classifier system. This involves the prefix se- (a short form of satu) joined to a category word.
- Seorang: Used for people (e.g., seorang guru - a teacher).
- Seekor: Used for animals (e.g., seekor anjing - a dog).
- Sebuah: Used for inanimate objects and abstract nouns (e.g., sebuah meja - a table; sebuah ide - an idea).
3. Direct Attachment of 'se-'
To express one with se- before a general object, use a classifier (sebuah meja, not semeja for a table); a bare noun or full satu plus noun can also be used. By contrast, the prefix se- is attached directly to nouns that function as units of measurement, time, or containers. For example: sehari (a day), segelas (a glass), or sekilo (a kilogram).
4. Indefinite 'Suatu'
For abstract nouns or to mean 'a certain' thing (often in stories), Indonesian uses suatu. For example, suatu hari means 'one day' or 'a certain day'. Unlike classifiers, suatu does not use the 'se-' prefix.
5. Singular Requirement
For one table, use sebuah meja, without adding productive plural repetition. This does not remove repetition that belongs to the word itself: seekor kupu-kupu (one butterfly) retains the whole lexical form.
Examples (5)
- Saya punya mobil.
I have a car.
Word by Word: I have car
In this common sentence, the bare noun 'mobil' functions as 'a car' without needing any extra words.
- Ada seekor kucing di taman.
There is a cat in the park.
Word by Word: There-is one-tail cat in park
Here, 'seekor' (se- + ekor) is used to specifically introduce 'a' cat as a new entity in the sentence.
- Dia adalah seorang dokter.
He/She is a doctor.
Word by Word: He/She is one-person doctor
In formal contexts, 'seorang' is used before professions to mean 'a'.
- Saya mau beli kamus.
I want to buy a dictionary.
Word by Word: I want buy dictionary
The focus is on the item type (dictionary), so no article or classifier is necessary.
- Ibu makan apel.
Mother is eating an apple.
Word by Word: Mother eat apple
A bare noun can represent a single item perfectly well in context.
Common Mistakes
Attaching 'se-' directly to a general object noun to mean 'a/an'.
Saya tinggal di serumah.Saya tinggal di sebuah rumah.To express one house with se-, use sebuah rumah; a bare rumah or satu rumah is also possible in suitable contexts. Se- directly attached to a general noun can have another meaning, as in serumah (in the same house). Units such as segelas and sehari allow direct attachment for one unit.
Pluralizing a noun when a classifier is present.
Ada dua buah meja-meja.Ada dua buah meja.Do not add productive plural repetition merely to repeat the quantity in dua buah meja. Lexical repetition remains intact: dua ekor kupu-kupu is correct because kupu-kupu is the word for butterfly, not a pluralized form of kupu.
Using 'sebuah' for people.
Saya adalah sebuah guru.Saya adalah seorang guru.'Sebuah' is for objects and abstract concepts. For people, you must use 'seorang'. However, in most cases, you can just say 'Saya guru'.
