Me and my brother are wanting to get matching tattoos. We want the word "Brother" or "Brothers" in Dovahkiin. I found some things online that translate it but I'm actually seeing if it's possible to find out how it would look in the Dragon Tongue writing, like the one see on the walls to learn new shouts. If anyone knows of a way to find it let me know please

Zeymah is the Dragon word for Brother(s).

So you're saying I should match the letters Zeymah to that chart, or the letters for Brothers?

Probably the letters for zeymah. You may want to ask over at the Lore Forum. They might have better insight on this.
