In some of its uses, moreover, over is a movable element, which can be prefixed at will to almost any verb or adjective of suitable sense, as freely as an adjective can be placed before a substantive or an adverb before an adjective. [OED]
此外,在某些用法中, over 是一个可移动元素,可以随意加在几乎任何合适意义的动词或形容词前,就像形容词可以放在名词前或副词可以放在形容词前一样自由。[OED]
