ah, etymology. i love it... i still think about the choice i made not to study literature and language (at least as a primary field) but i still get a kick out of reading up on language; roots, histories, uses, definitions... all of it. I just recently ran accross an interesting (more than useful) site for the online etymology dictionary. it comes in handy when you're wondering about the proper use of 'wax poetic' or other superfluous-by-modern-standards words and terms that catch your eye.
on a similar note, i finally looked up the etymology (or at least an approximation thereof) of the lone ranger's famous "kemo sabe". i won't go into it here, but suffice to say it sounds like no one really has any idea where it came from, but lots of people offer their opinions. personally i like the ojibwe root, partly because a grad student has tracked down an original reference, and partly because i am (in a small way) of ojibwe descent. read the article here if you like... it's a little annoying because of all the small ads, but the interesting text is interspersed throughout the page.
