Glioma/glioblastoma/oligodendrogliom. I quite like the way it sounds in Norwegian, but knowing what it is does take the pretty out of it. It's not the poor glial cells fault that they had to lend their name to a horrible illness! Glial cells are awesome! Also, I just really like pronouncing the glio-part.
Duodenum sounds awfully pretty to me, and a healthy one is a great thing to own!
