"You must be nervous, right?"

Translation: Kamu pasti gugup, ya?

[XavierLamb9]

"Kamu harus gugup, ya?" Is this also correct?

[demoksaputra]

That's not right. If you say "kamu harus gugup", it's like you're ordering the person you're talking to to be nervous.

In this kind of phrases "You must be/have to be/have got to be ..., right?" it's better to translate it to "Kamu pasti ..., ya?"

Kamu pasti gugup, tidak?
It's not accepted. But why not?
