"You fall."

Translation: Kalian jatuh.

[Mijntje43116]

It says kau... shouldn't it be kamu?

[duolingotfek]

You singular: kamu, kau
You plural: kalian

Note:

"Kamu" is generally more common and more polite than "kau". It's better to use "kamu"

[FarisAufa1]

Kau is only found in textbook or in movies subtitles, people dont usually speak "kau" in daily

[DanielCark]

In my version it says kalian .. but kau is also another (informal) way to say "you"

[Blooper_KINGPIN]

all my friends fell.

[Nocteliv]

Why does it say kalian for the word "you"?

[DanielCark]

Kalian means you (plural). As in y'all or youse

[Aiden212598]

Given the lack of context, I argue that all forms of "you" should be accepted considering that a 2-term sentence lacks much information. On the other hand, there might be further background information I lack in putting forward such an argument.

[ICHAKHALISA]

You is kamu[indonesian]

[AVAX3M]

"You" can also be "kalian" if "you" refers to more than one.

[Esquared87]

From the English, there's no way to know if it is singular or plural. So, they should not say "kamu" or "anda" is incorrect.
