shouldnt it be: "EvaNAK titkarnöje nagyon okos"?
There are two forms possible, long or short:
You made a strange mix of them.
thanks for replying! makes total sense to me now :)
Why isn't there an az at the beginning of the sentence?
"The Éva's secretary"? Proper names don't need an article.
Remember that the article for the secretary is hidden in the short form. The long form would be "Évának a titkárnője". There it is.
