Old Norse orthography

Old Norse orthography is the way people wrote words in Old Norse a long long time ago in places like Iceland, Norway, and Denmark. Imagine writing words using letters like A, B, and C but much much older versions of them.

Now imagine a time before proper spelling rules and dictionaries, when people just wrote down words as they sounded to them. And because everyone spoke a little differently depending on where they were from, the way they spelled words was also different. This is why even today, people from different parts of the world spell words in slightly different ways.

In old Norse, there were also special letters that aren't used so much anymore, like Þ and ð. The letter Þ looks like a lowercase “y” with a long tail on the bottom, and the letter ð looks like a lowercase “d” with a little line through it.

Overall, old Norse orthography can be pretty confusing to read and spell because it’s not used so much anymore, but it's still interesting to learn about how people communicated in the past!
