[Avodah] Fwd: Reshut Hyachid

[Galsaba at aol.com]

I wonder if the term "Reshut Hayachid" is a defentioion, describing an arae,
or if the term just describe Din of an area, depends on the context.
If "Reshut Hayachid" is a defention of an area, then I would assume that the 
same area would be called "Reshut Hayachid", no matter if we are dealing about 
Dinei Shabbat, Nezakim, or Tumeah.
 
How would I translate "Reshut Hayachid"? when I refer to Hilchot Shabbat, can 
I translate it "Private Domain"?
How would I translate "Reshut Hayachid" when I refer to Hilchot Nezakim, can 
I translate it "Private Property"? For example, if there is an area more than 
4 tefachim by 4 tefachim (and less than Beit Sea'tayim), and the area is 
surrounded by four mechitzot, more than 10 tefachim hight, and the area does not 
belong to anyone, (or belong to the City), and there is a Safek Tumeah there, 
will I judge the Tumea as Tumea Bereshut Hayachid? 
And if my Shor Hezik someone's else shor in that area, would it be considered 
as Heizek Bereshut Hayachid, or Heizwk Bershut Harabim?
