What is the meaning of easement?

easement is the right to a specific use of or right to travel over land owned by another. The land being used or traveled over is the servient tenement; the land that is benefited by the use is the dominant tenement. An easement appurtenant is a property interest belonging to the owner of dominant tenement and is transferred with the land; an easement in gross is a personal right that usually is not transferable by its owner. (See affirmative easement, dominant tenement, easement appurtenant, easement in gross, implied easement, negative easement, servient tenement).
