An eruv ([ (ʔ)eˈʁuv]; Hebrew: עירוב, lit. 'mixture', also transliterated as eiruv or erub, plural: eruvin [ (ʔ)eʁuˈvin] or eruvim) is a ritual halakhic enclosure made for the purpose of allowing activities which are normally prohibited on Shabbat (due to the prohibition of hotzaah mereshut lereshut), specifically: carrying objects from a private...

An eruv (ערוב, pronounced ay-roov), in modern terminology, is a technical boundary that allows Jews to carry in public areas on Shabbat. It is one of those traditions which has blossomed from a basic Torah principle into a highly complicated legal matter.

The term eruv refers to the act of mixing or combining, and is shorthand for eruv hazerot — the mixing of domains, in this case, the private (rashut hayahid) and the public (rashut harabim). An eruv does not allow for carrying items otherwise prohibited by Jewish law on Shabbat, such as money or cell phones.

According to the mishnah, if one is cut off from their eruv on Shabbat because it is locked in a cupboard to which the key has been lost, it remains a valid eruv. But Rabbi Eliezer disagrees. If the whereabouts of the key are unknown, the eruv is not a valid eruv.

An eruv enhances the Sabbath by facilitating carrying. Jewish law does not normally allow the carrying of objects in public spaces or between private and public spaces on the Sabbath, a prohibition based upon the biblical imperative to “do no work” on that day. This rule can make some simple activities complex.

The Hebrew word "eruv" means to mix or join together; an Eruv Chatzayrot (henceforth just "Eruv") serves to integrate a number of private and public properties into one larger private domain. Consequently, individuals within an Eruv district are then permitted to move objects across the pre-Eruv public domain-private domain boundary.

An eruv is a physical structure that allows Shabbat observant Jews to carry objects in public on Shabbat. To understand it more fully, we must first understand the prohibition on carrying on Shabbat and then how the eruv affects that. There are 39 categories of melachot, “work,” that are prohibited on Shabbat.

1) An eruv allows one to carry only items which are permitted to be used on Shabbat and are actually needed on Shabbat. 2) According to many authorities, it is not possible to create a kosher eruv for many urban areas, even if there are fewer than 600,000 that walk the streets.
