Couldn't I say excuse me?
is "-" needed?
I cannot see what you inputted to be able to answer.
Can you write here what your input was?
As I recall, it was something like: "Nu, scuzati-me" ? And that's why I asked if - is needed in between.
Ah, is must be scuzați-mă. Or, informally, scuză-mă.
Yes, it is needed.
"Pardon" hardly is a Romanian word. It came from French ~200 years ago and is only used by semi-literate people.
Languages are living things, changing with the times and culture.
