Questions & Answers about Saya membeli deterjen murah di pasar.

Can I say "Saya beli..." instead of "Saya membeli..."?

Yes. Both are correct. Membeli is the formal/politer form (meN- prefix + root), while beli is the bare verb commonly used in everyday speech. So:

• Formal/neutral: Saya membeli deterjen murah di pasar.
• Conversational: Saya beli deterjen murah di pasar.

Why is the adjective after the noun (deterjen murah), not before it?

In Indonesian, adjectives usually follow the noun they modify. So deterjen murah = “cheap detergent.” Putting it before (murah deterjen) is ungrammatical. Other examples: mobil merah (red car), rumah besar (big house).

How do I express “the cheap detergent” versus “a cheap detergent”?

Indonesian doesn’t have articles. You show specificity with demonstratives or context:

• Indefinite/generic: deterjen murah
• Specific/definite: deterjen murah itu (that/the cheap detergent)
• Emphasizing selection: deterjen yang murah (the one(s) that are cheap), e.g., Saya membeli deterjen yang murah, bukan yang mahal.

How do I show past, present, or future? The sentence looks “tenseless.”

Indonesian doesn’t inflect for tense. Use time words or aspect markers:

• Completed: Saya sudah membeli... / Saya telah membeli... (formal)
• Just now: Saya baru (saja) membeli...
• Earlier/today/yesterday: Saya tadi/tadi pagi/kemarin membeli...
• Future/intention: Saya akan/mau membeli...

• sebotol deterjen cair = a bottle of liquid detergent

  • di pasar (at the market)
  • dibeli (bought [passive])

Could murah be describing pasar instead of deterjen here?
