Due to the Norwegian language conflict there have been various competing forms of written Norwegian over time, two of which have been officially recognized as equally valid by the Norwegian parliament since 1885. Both apparently changed their spelling of "slut" to "sludd" in the 21st century, Bokmål in 2005 and Nynorsk in 2012, presumably in an effort to encourage English speakers to make jokes about Swedes and Danes instead of them.
