So I can add it to German, Latin and Gaelic as another language slowly fading? *\;-) (I'm actually encouraged from time to time to get back into Latin because it's in our BCP, if only for headings.)
Actually, if I were around Greek I probably would learn it. Let's see, let me make some guesses:
"chrys(o?)" is probably gold (not sure where I'm reaching for that...)
"(o?)stom(o?)" is definitely mouth (colostomy - "the practice of having/making a mouth for the colon"?)
"(o?)s" likely a suffix indicating singular, "one" or "the one"
(I did all this without googling or any other reference. How'm I doing?)
Such a smart Xenos! (Now figure out Xenos!:) )
As a classics major in my college days, I recommend keeping up with the Latin, btw! Of course it was a living language back then!
