But we may ask how the verbrattle came to have such a sense. The earliest use of the word is found in a name,Johannes Ratellebagg, recorded in a document of around 1273; the earliest use of the word as a common noun (in the sense "to flap, used of a banner") is found in a work written about 1300and copied in manuscript around 1330.It is thought that the word probably comes from Middle Dutchratelen, which may be imitative in origin. In any case,the wordratelen was used mainly in intransitive senses such as "to make a rattling sound.”Already in Middle English, however, the transitive sense "to babble something" existed,and other transitive senses,as in "to make something rattle,” "to stir up, rouse,” "to drive in a rapid, rattling manner,” came into existence from the 16th century on.The transitive sense "to unnerve,”that is, "to make somebody rattle,” is first found in an American work of 1869.词语用法专题小组中有相当一部分人（百分之八十六）都同意rattle 这个词有“使人不安”的意思， 1969年出版的美国经典辞书 第一版收录了这一意思。 但人们不禁要问动词rattle 为何有了这个意思。 该词最早的使用发现于1273年前后记载的一个文件中的Johannes Ratellebagg 这个名字中； 1300年这个词第一次被用作普通名词（意为“飘扬，用于旗帜”），1330年又见于手抄的印本中。人们认为这个词可能来自原来可能是拟声词的中古德语ratelen 。 不过无论怎样，ratelen 这个词本来只是作为不及物动词来使用， 如发出嘎嘎声等意思。在中古英语中，“含糊不清地说出”这一及物动词的意思就已存在，该词其它的及物意思，如“使发出嘎嘎声”、“激起，唤醒”“嘎嘎响地急速向前拖”从16世纪开始就形成了。及物意思“使不安，”即“使某人惊慌”首先出现于1869年的美国作品中〔speed〕The dancer's breathing quickened as she approached the end of her solo.舞蹈家在接近她独舞的尾声时呼吸变得急速了。〔slow〕 Deliberate suggests a lack of hurry traceableespecially to caution, need, self-restraint, or careful consideration, as of consequences: Deliberate 表示缺少急速，尤指由小心、需要、自我约束或对后果的认真考虑所引起的： 〔frantic〕Characterized by rapid and disordered or nervous activity:狂暴的：有急速并纷乱或紧张的行为特点的：〔shake〕To move to and fro in short, irregular, often jerky movements.摇动：以短的、不规律的、常常急速的运动来回移动〔whirlwind〕Tumultuous or rapid:喧嚣混乱的、急速的：〔press〕To require haste; be urgent.催逼：需要急速的；紧急〔tremolo〕A tremulous effect produced by rapid repetition of a single tone.震音：一种由急速的重复一上单音而形成的震颤效果〔knock〕To strike a sharp, audible blow or series of blows, as on a door.猛烈敲击：急速而又能被人听见的一次或多次敲击，如敲门〔tearing〕Marked by great or violent haste:急速的：以非常的或极端的匆忙为标志的：〔myoclonus〕A sudden twitching of muscles or parts of muscles, without any rhythm or pattern, occurring in various brain disorders.肌阵挛：肌肉和部分肌肉的急速抽动，它没有任何节律或方式，存在于各种脑失调症〔prevailing〕Rife implies that something is current, plentiful, or rapidly spreading or increasing: Rife 指现存的，大量的或急速扩展或增加的东西： 〔haste〕Rapidity of action or motion.急速：行动或动作的快速性〔flit〕A fluttering or darting movement.飞掠，轻快的动作：颤动的或急速的运动〔tachylyte〕Greek takhu- [tachy-] 希腊语 takhu- [前缀，表示“急速的”] 〔shoot〕To utter (sounds or words) forcefully, rapidly, or suddenly:连珠炮似地说出：有力、急速或突然地发出（声音或说话）：〔idiopathy〕A primary disease arising spontaneously with no apparent external cause.突发性疾病：急速发生的没有明显外在症状的第一期疾病〔hasty〕Characterized by speed; rapid.See Synonyms at fast 1具有急速特征的；快的 参见 fast1 |
