"Mi lányok vagyunk, ti pedig fiúk."

Translation: We are girls, and you are boys.

[CynthiaKin6]

why is 'leanyok' not correct?

[RichieMB]

Report it, I think leányok is correct.

[MrtonPolgr]

It's correct, be aware it's oldish/can sound like some literary cliché.

[Renardo_11]

I first encountered this form visiting Leányvár, the girls' fortress of the roman castle Kelemantia east of Komárom / Révkomárom. It's on the Slovak side since 1919.

[Andrew2569]

Because the word is lányok, not leanyok.

[Judit294350]

Actually leány is an alternative to lány. I've only seen it in songs and poetry - but it is still valid.

[gephardt]

How about "we are girls and you boys?"

[TamsMar]

I think English requires a second 'are'

[ataltane]

It doesn't require it, but the form without the second 'are' is rather literary in style.
