Eruv

An eruv ([ʔeˈʁuv]; Hebrew:עירוב‎, "mixture", also transliterated as eiruv or erub, plural: eruvin [ʔeʁuˈvin]) is a ritual enclosure that some Jewish communities, and especially Orthodox Jewish communities, construct in their neighborhoods as a way to permit Jewish residents or visitors to carry certain objects outside their own homes on Sabbath and Yom Kippur. An eruv accomplishes this by integrating a number of private and public properties into one larger private domain, thereby avoiding restrictions on carrying objects from the private to the public domain on Sabbath and holidays.
