Learn Hardcore Indonesian: Kamar tamu kami bersih dan rapi.

Indonesian doesn’t need a copula before adjectives. Adjectives can be predicates by themselves: Kamar tamu kami bersih dan rapi = “Our guest room is clean and tidy.” Generally, don’t use adalah before adjectives; it’s mainly used before nouns (e.g., Dia adalah dokter).

Why is kami after the noun? Can I put it before?

Possessive pronouns follow the noun in Indonesian. kamar kami = “our room,” kamar tamu kami = “our guest room.” You don’t put kami before the noun. A heavier option is kamar tamu milik kami, but kamar tamu kami is more natural.

What’s the difference between kami and kita here?

kami = we/our, excluding the listener.
kita = we/our, including the listener. So kamar tamu kami excludes the person you’re speaking to from ownership. Use kita if you want to include them: kamar tamu kita.

Can I say “my guest room” with the suffix -ku?

Yes:

kamar tamuku = my guest room
kamar tamumu = your (singular) guest room
kamar tamunya = his/her/their guest room or “the guest room” (definite) You can also use full pronouns: kamar tamu saya/Anda/dia.

Could kamar tamu kami mean “our guests’ rooms”?

No. kamar tamu is a fixed compound meaning “guest room.” To say “the rooms of our guests,” use kamar para tamu kami or kamar tamu-tamu kami.

What’s the nuance between bersih and rapi?

bersih = clean (free from dirt, stains, smells).
rapi = neat/tidy (well-arranged, orderly). A room can be bersih but messy, or rapi but dusty. Together they cover both hygiene and order.
