I have been trying to find out whether there is a link between these two words. In Turkic dialects, Bora means "Northern Wind" ~ "Northern snowy whirlwind". Might or might not be related with the verb "bur" meaning "to twist, wind round" What is the etymology of "Aurora Borialis"? Is the "Borialis" part related with the Turkic word Bora (Bora is also a common given name. It's a common practice to give babies names of nature) Is there any possibility that the name Aurora is related with the Turkic root "*or-" meaning "shine". Or maybe *jar- meaning "shine, dawn, light" http://starling.rinet.ru/cgi-bin/re...ny=&method_any=substring&sort=proto&ic_any=on Then again, there is the word "Bura" I talked about earlier meaning "the spirit horse that takes a holy person to Northern Star" so it could also be related with the direction itself. I'm not sure.
