Yr is the letter Y
Anglo-Saxon rune poem (from ragweedforge.com)
Yr is a source of joy and honour to every prince and knight;
it looks well on a horse and is a reliable equipment for a journey
Yr reversed indicates a lack of skill or ability, and that events, people and situations will be teaching you about the skills you lack. I find it also is indicative of the hands, and that specially attention should be paid attention to the hands during this time, especially if you work with your hands a lot.
