Last time we covered the Elder Runes, which are the ones most people learn first. This is primarily because they have enough characters with similar sounds to function as letters in modern English. The Younger Futhark runes were developed between 700-800 CE, right near the beginning of what we often call 'The Viking Age'. The vast majority of rune stones, and inscribed 'viking' swords you'll likely ever see are going to be written in this text. If you want to write Old Norse in runes, the Younger Futhark are what you would use!
