The fable of the tortoise and the hare teaches us that speed does not always spell success. Historically in English, however, it does: the Old English word sp¶, from which our word speed is descended, originally meant “prosperity, successful outcome, ability, or quickness.”A corresponding verb, sp¶, in Modern English the verb speed, meant “to succeed, prosper, or achieve a goal”; and an adjective, sp¶, the ancestor of our word speedy, meant “wealthy, powerful.” Except for archaic uses the words today relate only to the general sense of “velocity.” The meaning “success” is retained chiefly in the compound Godspeed, a noun formed from the phrase meaning “God prosper you.”
乌龟与兔子这则寓言故事告诉我们速度并不总意味着成功。然而在英语的历史中，速度就意味着成功：speed 这个词来自古英语单词 sp¶d ， 原意为“繁荣昌盛，成功的结果，能力或速度”。与之相应的动词spedan ， 即现代英语中speed 一词，意为“取得成功，繁荣昌盛或实现一目标”； speedy 的前身，形容词 sp¶g ，则表示“富有的，有力的”。 除了其古代用法，这些词今天只和“速度”这一一般意义有关。“成功”之意主要保留于Godspeed （成功、幸运、天惠） 这个词中， 这是一个来自词组“祝你成功”的一个名词
