I was just listening to a Titah (speech) by HM Sultan of Brunei to celebrate Brunei's 34th National Day. What is splendid about this titah is that the full speech is available on Youtube (here) and also in written form from the Prime Minister's Office (here). This means I can listen to it and then check anything I don't understand from the written version.
It is also interesting to see where they deviate. At location 2 min 2 sec into the recording, HM says:
Oleh itu dalam apa pun keadaan, kita mestilah berusaha ...
(Because of this, in whatever situation, we must make an effort ...)
but the official text has:
Oleh itu dalam apa jua keadaan, kita mestilah berusaha ...
I wonder what this difference between pun and jua signifies.
