arch在狭义上是拱门,约等于一个二维的结构。举个例子,凯旋门的英文是triumphal arch,由此可以知道这里arch用来形容的是“门”,一个二维的结构。可以同时参考一下英文释义:a curved symmetrical structure spanning an opening and typically supporting the weight of a bridge, roof, or wall above it. • an arched structure forming a passageway or a ceremonial monument: a triumphal arch. • a shape resembling an arch or a thing with such a shape: the delicate arch of his eyebrows. • the inner side of the foot.vault表示三维的拱顶,是多个arch在不同二维平面组成的三维结构。英文释义见:1 a roof in the form of an arch or a series of arches, typical of churches and other large, formal buildings. • literary a thing resembling an arched roof, especially the sky: the vault of heaven. • Anatomy the arched roof of a cavity, especially that of the skull: the cranial vault.个人觉得这二者的关系近似中国古建筑中的椽、檩、梁、枋与整个屋顶的关系。

arch的基本意思是“拱,拱门”,用于比喻则表示“拱形物”。前缀arch-来源于希腊语的拉丁化前缀arkh-, arkhi-,意思是“chief, principal; extreme, ultra; early, primitive”,意思:主要的,总的。前缀archi-,arche-是前缀arch-变化型。当作为活用前缀时,一般加在人称名词上,通常还具有轻蔑效果,如:arch-liar 大骗子,这个构成单词能力一般一般可自由地与名词结合,构成新词。其中,主要是与人有关的名词,如:archduke。另外,arch 可以独立为形容词,如:arch smile 狡猾的微笑。
