Hello,
 
Sometimes I feel a bit confused about how to pronounce the " r " ending in certain words.  Here are a couple of questions I have:
 
1. Are all R's rolled?  For example, are both R's in "ormr" rolled? Or both in "dvergr"? 
Sometimes I find myself voicing the first R in these cases as you would an English R, and rolling only the second R.
 
( -r represents the R that is being rolled)
 
orm-r
dverg-r
varg-r
 
What is the correct form?
 
2.  Ending R's -  do they have tone, or simple an unvoiced flap of the tongue?
 
More likely than not I will never speak this language to anyone aloud, but for my own satisfaction and respect of the language I would like to be as close and accurate as I can.  What are your views?
