Hi Óskar and all,

Let me comment shortly on this to clarify the point. The ending has
quite a history from Proto-Germanic to Old Norse. Let's take the word
"arm" as an example:

-z is pronounced as a voiced s

From about 500 on in Scandinavia it became:
the -R stands for a fricative r (pronounced slightly like -rsh, but
don't overemphasize the -sh)

In Old Norse it finally became:
pronounced as trilled r

So the romanized -R ending is used to indicate a linguistic point of
development in Scandinavia roughly between 500 - 800. We only have
witness for this from runic inscriptions, it was the time when the
Younger Futharc just had emerged. For Old Norse the -R ending (capital
spelling) never should be used.

Greetings and best wishes,

Kurt Oertel
