Nos lowen is a phrase that comes from Cornwall, which is a place in the southwest of England. It means "happy night" in the Cornish language.
Imagine that you are going to a party with your friends. Everyone is there, and there is lots of food and music. You play games and dance all night. That is what nos lowen is like – it’s a party where everyone has a good time.
Cornwall is a place with a very rich history and culture. People there have their own language, music, and traditions. When they have a nos lowen celebration, they enjoy each other's company and celebrate their culture.
Just like when you have a birthday party where you celebrate another year of life, a nos lowen celebration is a way to be happy and appreciate the good things in life. It’s a time to be with friends and family and have fun together. It’s like having a big, happy family gathering with music, dancing, and lots of laughter.
