'Lovely' is often used when something is nice, sweet or wholesome. You could have a lovely dinner with your family, someone could give you a lovely present, or someone could be a lovely person.

Hello You can compliment someone using this word when a person or an animal has done something cute, for example: Your cat purrs so often! How lovely it is!

I use lovely a lot. What a lovely day! He has a lovely smile. She has a lovely personally. You look lovely in that dress. I had a lovely time I probably overuse it to be honest 🙂

I use lovely all the time. She has a lovely voice. That cat is lovely. We've had a lovely time.

Yes, lovely is very common. Anyone can use it for anything :) Do you have a context for how someone used it?
