Questions & Answers about Dia memompa ban sepeda di rumah.

What does "Dia" mean? Is it he or she? Are there more formal options?

• Dia is a gender-neutral third-person singular pronoun: it can mean either he or she.
• More formal/respectful: beliau (used for respected people).
• Literary/very formal: ia (often in written narrative).
• Plural “they”: mereka.
• To make gender explicit, add a noun if needed: dia (laki-laki) = he (male), dia (perempuan) = she (female).

Why is it "memompa" and not "mengompa" or "mempompa"?

• The verb is formed with the active prefix meN-
  • root. For roots starting with p, the prefix becomes mem- and the initial p of the root drops.
• Root: pompa → meN- + pompa → memompa (p drops: mem + ompa).
• Similar patterns: pukul → memukul, potong → memotong. So mengompa/mempompa are incorrect here.

Can I say "Dia pompa ban sepeda" in casual speech?

• In casual Indonesian (especially Jakarta speech), dropping meN- is common: Dia pompa ban sepeda is understood.
• Even more colloquial: Dia ngompa ban.
• In standard/neutral Indonesian, use Dia memompa ban sepeda.
