One of the 39 Melachot is Hotzah, [[carrying]] from one domain to another. In general, one may not carry from a public domain to a private one, or visa versa. Additionally, one may not carry 4 [[amot]] in a public domain. The definition of these domains and the exceptions under which a person may carry are described below. For a broader perspective about [[carrying on Shabbat]] and the modern Eruv, see our [[Introduction to the Modern Eruv]].
