In reply to:

okay Marty, I'll give the first word--zwo should be zwie (as in zweibach-- a nabisco cracker/biscuit for teething babies.)

I wonder if anyone can confirm my suspicion that "zwo" is the Low German equivalent of "zwei"? I remember reading somewhere that English has more in common with Low German than with High, and the zwo/zwei comparison was cited as an example. Also, if my high school German has not totally abandoned me, doesn't "Zwieback" literally mean "twice baked"? If so, a zwieback biscuit would be a near perfect example of the Germanic/Norman redundant pairings that tsuwm and Father Steve were talking about. The one thing that interest me is how "zwei" became "zwie" in Zwieback. Any ideas?
