Thank you (I think), Bill. I could get lost on this site for hours. What a delight. It confirmed one of several surprising things a linguistics professor said in a class many years ago: that, in effect, "an orange" used to be "a norange." But not his claim that "gorilla" was originally "porilla" -- but a Greek scribe left one of the vertical lines off the "pi" turning it into a "gamma."
