Nice is a very common adjective in English but, what other words can you use to express something nice or to say something nice about someone?
amiable charming considerate cordial courteous
delightful friendly gracious kind lovely pleasant
fine and dandy
But be careful because you can use some of these to describe things and some to describe people. And also a cultural difference often, is that in British English, it is not common to over exaggerate so be careful!
Examples:
What a charming, considerate person
It’s a lovely, pleasant day
My mother is so gracious and kind
He is an amiable, courteous boss
I had a delightful day
I’m feeling fine and dandy today
