Why is it "nem hall" and not "nem tud hallani"?
Is 'öreg' also correct here?
Yes it should be but it's still not been accepted!
What is the difference between "régi" és "idős" ?
Régi is used for object, idős is for people.
The word "öreg" should be added for the translation of "old".
"öreg ember" nem eleg old man?
