[Middle English spede, from Old English sp d, success, swiftness; see sp- in Indo-European roots.]Synonyms: speed, hurry, hasten, quicken, accelerate, precipitate These verbs mean to proceed or cause to proceed rapidly or more rapidly. Speed refers to swift motion or action: The train sped through the countryside. Postal workers labored overtime to speed delivery of the holiday mail. Hurry implies a markedly faster rate than usual, often with concomitant confusion or commotion: Hurry, or you'll miss the plane! Don't let anyone hurry you into making a decision. Hasten suggests urgency and often eager or rash swiftness: My doctor hastened to reassure me that the tests were negative. His off-color jokes only hastened his dismissal. Quicken and especially accelerate refer to increase in rate of activity, growth, or progress: The skater's breathing quickened as he neared the end of his routine. The runner quickened her pace as she drew near the finish line. The economic expansion has continued but is no longer accelerating. Heat greatly accelerates the deterioration of perishable foods. Precipitate implies causing something to happen abruptly or prematurely: Mention of the issue precipitated an angry outburst during the meeting. See Also Synonyms at haste. Word History: We learn from the fable of the tortoise and the hare that the race is not always to the swift, but etymology teaches us that speed and success are closely related. The Old English word sp d, from which our word speed is descended, originally meant "prosperity, successful outcome, ability, or quickness." A corresponding verb, spdan, in Modern English the verb speed, meant "to succeed, prosper, or achieve a goal"; and an adjective, spdig, 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 "May God cause you to prosper." |
