"The boys do not study in July."

Translation: A fiúk nem tanulnak júliusban.

[MilosVlahovic]

Why is "A fiúk júliusban nem tanulnak" wrong? Is it the word order?

[bdori]

Your sentence is correct, too. (Except for a spelling mistake: "fiúk" instead of "fúuk".)

Tnx. Edited.

I think it sounds a bit unusual but it's not incorrect per se.
