"What a beautiful woman!"
Translation:Quelle belle femme !
i have this question as well, why is there no article in this sentence?
You don't need an article because there already is a determiner: the exclamative adjective "quelle".
"Quel, quelle, quels, quelles" can be found in two types of sentences: questions or exclamations.
Quelle robe mets-tu ? = Which dress are you putting on?
Quelle belle robe ! = What a beautiful dress!
That's where you hit the language barrier. It makes perfect sense in Swedish, actually
