Riksmål is a way of speaking and writing words in Norwegian that is similar to the way people used to speak and write in the olden days. It is a bit like a fancy or formal version of Norwegian.
Think of it like this: Imagine you are playing dress-up and you want to look extra special for a party. You might put on a dress or a suit that is fancier than your normal clothes. Riksmål is like that fancy dress or suit – it is a way of using words that is fancier than normal Norwegian words.
Some people in Norway like to use riksmål when they write or speak because it sounds more official or educated. However, others think that using riksmål makes Norwegian seem old-fashioned and that it is better to use more modern words.
Overall, riksmål is just one way of using Norwegian – it is like a special version that some people like to use to show off their language skills or to sound more formal.
