"Vi estos lacaj post tia laboro."

Translation: You will be tired after that kind of work.

Why is is "lacaj" here?

[vikungen]

Why it is plural?

Because we're using a plural you.

Vi estos laca = you (singular) will be tired

Vi estos lacaj = you (plural) will be tired

That means the sentence is talking to more than one person.

Yet, "You will all be tired after that kind of work" was rejected.

[Davgwynne]

Perhaps not all of the people being spoken to will be tired, just a group of them.

[DanieloRegulo]

I would report it.

[AliVeTree]

What's the difference between 'vi' and 'vi ĉiuj' in this context?

[ConstantJoe]

Ahh, dankon!
