Mains (Scottish Gaelic: Mànas) in Scotland normally refers to farms. It is a pseudo-plural, actually being a Lowland Scots corruption of the French demesne, and so is never used in the form "Main", except occasionally "Main farm", although this usage is not traditional. A mains is the equivalent of a home farm, or sometimes even a manor in England, and was usually a larger farm on an estate, or at least the one with more fertile ground.
