Translation:Everyone is wearing a white hat.
I thought white hood which made me think of ku klux klan :0
So is, iedereen always will the sing. 3rd not plural?
Yes. "iedereen" is always used with the verb in the 3rd person singular. "alle" is used with the 3rd person plural.
Why not "Each wears a white hat"?
What would you mean by that? Each what?
'Iedereen' means everyone
In English, we can use "each" to mean "everyone" such as "To each his own."
Ah, I see. You could use "Ieder". That works.
