Editing Mechitza (section)

===Eruv===
{{main|Eruv}}
In halakhic discourse, "mechitza" can also refer to the boundary walls of an [[eruv|eruv for carrying]] (to [[Hotzaah|carry within a given area]] on the [[shabbat|Sabbath]] the area must be entirely enclosed). There are many specific rules for what constitutes a valid mechitza, although the mechitza does not have to be solid. (For example, there are many instances where part of an eruv may be a string run across several poles, and this could constitute a valid mechitza).
