Eruv

Enclosure allowing activities normally prohibited on Shabbat

An eruv is a ritual halakhic enclosure made for the purpose of allowing activities which are normally prohibited on Shabbat, specifically: carrying objects from a private domain to a semi-public domain (carmelit), and transporting objects four cubits or more within a semi-public domain. The enclosure is found within some Jewish communities, especially Orthodox ones.
