A wall is a structure that defines an area, carries a load, or provides shelter or security. There are many kinds of walls: * Defensive walls in fortification * Walls in buildings that form a fundamental part of the superstructure or separate interior sections, sometimes for fire safety * Retaining walls, which hold back earth, stone, or water * Walls that protect from oceans (seawalls or rivers levees) * Permanent, solid fences * Border barriers between countries * Brick wall * Stone wall ==Etymology== ''Wall'' comes from Latin ''vallum'' meaning "...an earthen wall or rampart set with palisades, a row or line of stakes, a wall, a rampart, fortification..." while the Latin word ''murus'' means a defensive stone wall〔Wall. Whitney, William Dwight, and Benjamin E. Smith. ''The Century dictionary and cyclopedia'', vol. 8. New York: Century Co., 1901. 6,809. Print.〕 English uses the same word to mean an external wall and the internal sides of a room, but this is not universal. Many languages distinguish between the two. In German, some of this distinction can be seen between ''Wand'' and ''Mauer'', in Spanish between ''pared'' and ''muro''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wall」の詳細全文を読む スポンサード リンク
