Grammar Rule in 30 Seconds

In Indonesian, you make most nouns plural by simply repeating the word twice with a hyphen.

  • Repeat the noun: 'buku' (book) becomes 'buku-buku' (books).
  • Use hyphens: Always connect the two words with a hyphen.
  • Context matters: If the sentence implies many, you don't always need to repeat the word.
Noun + '-' + Noun = Plural Noun

Meanings

Reduplication is the standard method for indicating plurality in Indonesian nouns when the plural sense is not already clear from context.

Indicates multiple distinct items of the same category.

“meja-meja”

“kursi-kursi”

2

Variety/Diversity

Suggests a variety of types within a category.
