Danish and Norwegian:
* krohn-uh (with a soft "h" sound)
Swedish:
* kro-nah (with a short, sharp "o" sound)
German:
* kroh-nuh (similar to the Danish pronunciation, but with a slightly stronger "h" sound)
English:
* krohn (often used as a loanword for the Danish and Norwegian currency, though not the most accurate pronunciation)
It's always best to check the specific context and language to ensure you are pronouncing "krone" correctly.
