Fence

A fence is something built like a wall, often made of metal or wood, to keep something in or to keep something out.  It differs from a wall, which has a foundation. Fences are usually supported by fenceposts. Fences can be large or small. Many are used in gardens or farms. Some are portable. A fence differs from a wall in not having a solid foundation along its whole length.

Alternatives to fencing include a ditch (sometimes filled with water, forming a moat).
