-blindly attempting to enforce latin on a Greek word

... by analogy with criterion~criteria?

i do have a friend who gets annoyed when people make the plural of octopus into octopi, as the ending is not -us but -pus (and not latin, but greek!) and so the plural should be octopoda, or so i'm told. but she doesn't go about enforcing this. :-)

but in any event, i went to georgetown, where we've been cheerfully mixing greek and latin for centuries. hoya saxa!
