<注釋>A large proportion (8' percent) of the Usage Panel approved the use of the verbrattle in the sense .to unnerve. in the first edition ofThe American Heritage Dictionary, published in 9'9. 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 273; 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 300and copied in manuscript around 330.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 'th century on.The transitive sense .to unnerve,.that is, .to make somebody rattle,. is first found in an American work of 8'9.
詞語用法專題小組中有相當一部分人（百分之八十六）都同意rattle 這個詞有.使人不安.的意思， 9'9年出版的美國經典辭書 第一版收錄了這一意思。 但人們不禁要問動詞rattle 為何有了這個意思。 該詞最早的使用發現於273年前後記載的一個檔案中的Johannes Ratellebagg 這個名字中； 300年這個詞第一次被用作普通名詞（意為.飄揚，用於旗幟.），330年又見於手抄的印本中。人們認為這個詞可能來自原來可能是擬聲詞的中古德文ratelen 。 不過無論怎樣，ratelen 這個詞本來只是作為不及物動詞來使用， 如發出嘎嘎聲等意思。在中古英文中，.含糊不清地說出.這一及物動詞的意思就已存在，該詞其它的及物意思，如.使發出嘎嘎聲.、.激起，喚醒..嘎嘎響地急速向前拖.從'世紀開始就形成了。及物意思.使不安，.即.使某人驚慌.首先出現於8'9年的美國作品中
