The official Malay language (used in texts and official communication) is understood and used by neighbouring Malaysia & Indonesia. However each country, including Brunei, has their own local dialect. Each district in Brunei also has its own variation.
Typical Greeting include:
• Good Morning: Selamat pagi (sounds like “pag-ee”)
• Good Day: Selamat sore (sounds like “sore-ee”)
• Good Afternoon: Selamat siang (sounds like “see-ahng”)
• Good Evening/Night: Selamat malam (sounds like “mah-lahm”)
• Good Night to Someone Going to Sleep: Selamat tidur (sounds like “tee-dure”)
Indonesians prefer to say “selamat siang” as a greeting in the afternoon, while Malaysians often use “selamat tengah hari.” Mispronouncing the “i” in siang may yield funny looks from your taxi driver; saying – the word for “sweetheart” or “darling” sounds close.
