Why does férfiak have an extra a?
.
It's irregular.
Why "a főnökök", not "azok főnökök"?
azok is the plural the az that means "that".
The az that means "the" doesn't change in the plural.
Azok a főnökök férfiak would be "Those bosses are men."
I reversed the word order and it still marked me right. So what would be 'men are the bosses' in Hungarian?
'men are the bosses' - A férfiak a főnökök.
