tak is slang for tidak.
Is "Kami tidak (di?)izinkan berbicara." also correct? I jyst learned that word today.
Kami tidak diizinkan berbicara = We are not permitted to speak.
Yes, that's a very nice, polite way to say...."We must STFU" :)
It should be accepted as well I think.
It's much better than...."Kita harus tutup mulut" ... or ... "Kita harus diam"...
are "tutup mulut" and "diam" rude?
Like shut your mouth or SILENCE
