Tim, - you seem to be interpreting my words (and the examples
I gave) according to a world of your own. Can you enlighten me (us)?
How can you accept that these are two different languages:

Old: Mörðr  hét maðr  er kallaðr  var gígja; hann var sonr
Mod: Mörður hét maður er kallaður var gígja; hann var sonur

I don't accept that they are different.  What I'm saying is that the point is
made and I will keep it in mind as I continue my study.  Other than that, it
has little relevance unless our two listowners give it such in their future
