FIELD SEPARATOR is a term used to describe a physical or virtual barrier that divides two distinct areas. FENCE (5 letters) and HEDGEROW (8 letters) are two examples of physical field separators. A FENCE is typically made of wood, metal, or other materials and is used to keep animals or people in or out of an area. A HEDGEROW is a line of shrubs or trees planted close together to form a barrier. Both fences and hedgerows can be used to separate fields or other areas of land.
